The Dr. Hyman Show - The Root Causes And Treatment For PCOS with Dr. Heather Huddleston

Episode Date: September 7, 2022

This episode is brought to you by Rupa Health, Cozy Earth, and BiOptimizers. Polycystic ovary syndrome, or PCOS, affects 5 to 10% of women in their childbearing years. Despite the many women struggling with the difficult symptoms of PCOS, we still know little about it. Those symptoms can include irregular or missing periods, excessive hair growth or hair loss, acne, and weight gain. Sadly, the average woman with PCOS sees four doctors before receiving a diagnosis. Today on The Doctor’s Farmacy, I’m excited to talk to Dr. Heather Huddleston to dig into the nuances and research around PCOS. Dr. Huddleston is the founder of the UCSF Multi-disciplinary PCOS Clinic and Research Center. This clinic provides care via an integrated group of providers with expertise in reproductive endocrinology, dermatology, nutrition, and psychology. Through the associated research program, Dr. Huddleston oversees investigations aimed at advancing our understanding of how physical activity, depression, cognition, sleep, and metabolic health all contribute to the manifestations of PCOS. Dr. Huddleston is passionate about broadly improving the care of patients with PCOS and serves as a medical advisor to Allara Health, which is an all-in-one virtual care platform for people with PCOS.  This episode is brought to you by Rupa Health, Cozy Earth, and BiOptimizers.

Coming up on this episode of The Doctor's Pharmacy. I think a lot of patients with PCOS sort of end up getting bounced around to different doctors, never really getting great explanations about what's going on with them and what are sort of some appropriate treatment pathways for them. Hey everyone, it's Dr. Mark. Like many of you, I'm terrifically busy throughout the week. I'm a doctor, a podcast host, a writer, a speaker, a father. And on top of all those commitments, I have to make time to prioritize my own health along with the health of my patients.

Because I have so much on my plate, I value tools that make my life easier. And I'm sure you can relate. And that's why I'm really excited to share with you today a little bit about Rupa Health. When I treat my patients, I look at a lot of indicators such as hormones, organic acids, nutrient levels, inflammatory factors, gut bacteria, all to dig deep down to find the root causes that prevent those patients of mine from optimizing their health and wellness. But that means I'm usually placing orders through multiple labs, which is just overall pain. Plus it makes keeping track of results more difficult for me and my patients. But all that changed when I started using Rupa Health. Rupa Health is a place for functional medicine practitioners to access more than 2,000 specialty lab tests from

over 20 labs like Dutch, Vibrant America, Genova, Great Plains, and more. Rupa Health helps provide a significantly better experience for both you and your patients. It's 90% faster than ordering tests one by one, and it lets you simplify the process of getting the tests you need. This is great for me because like most practitioners, I'd rather be spending that time with my patients and not doing administrative work. And that's the great benefit Rupa Health provides. This is a much needed option in the functional medicine space. It means better service for you and your patients. You can check out a free live demo with a Q&A or create an account at rupahealth.com.

I don't think there's anything better than waking up feeling super rested, relaxed, and energized. When we get high quality sleep, that's the norm. Without it, our simple day-to-day tasks can seem impossible and our health suffers. That's why I'm always looking for ways to upgrade my sleep routine and bamboo sheet sets from Cozy Earth is my new favorite way to get an amazing night's rest. You might be surprised to learn that many types of bedding out there contain toxins that can off-gas into your air and absorb into your skin. Do you want to sleep on formaldehyde? I don't either. So I know that Cozy Earth's products are certified to be free from harmful chemicals and that's why I love them. Sleep actually impacts every part of our health. It helps us maintain a healthy weight by balancing hormones and blood sugar, provides time to detox our brains, lets our muscles and organs rest and

repair. But so many of us don't get enough sleep or the right quality of sleep to allow the body to do all these important things. Better sleep is the cornerstone of better health and is something we all have the power to work on. I know nice bedding can feel like a big investment, so Cozy Earth makes it super easy to try out their products with a 30-day free trial and a 10-year warranty.

Now let's get back to this week's episode of The Doctor's Pharmacy.

Welcome to The Doctor's Pharmacy. I'm Dr. Mark Hyman. That's pharmacy with an F, a place for conversations that matter. If you struggle with hormones, if you've had something called PCOS or know someone with it or know anybody with infertility or acne

or irregular periods, this podcast might be quite interesting for you something called PCOS or knowing someone with it or know anybody with infertility or acne or irregular periods, this podcast might be quite interesting for you because we're going to discuss polycystic ovarian syndrome, a really common problem that affects so many women, maybe 5% to 10% of women in America and around the world. And we're talking to an expert in PCOS, Dr. Heather Huddleston. She's a professor of OBGYN and reproductive sciences. She's a specialist in reproductive endocrinology and fertility and cares for people with a whole bunch of reproductive and fertility issues. She's really interested in PCOS, polycystic ovarian syndrome, and other things like recurrent pregnancy loss, uterine disorders. She is the founder of the

UCSF Multidisciplinary PCOS Clinic and Research Center. And that clinic provides care with an integrated group of doctors and providers with expertise in reproductive endocrinology, dermatology, nutrition. I love that. And psychology. She also does a lot of research, oversees programs on how we can understand exercise, depression, cognition, sleep, metabolic health, and how all that affects PCOS. She's taught all over the place. She's published in major journals. And she's a graduate of Harvard Medical School. She's done her OBGYN and fellowship in endocrinology at

Brigham Women's Hospital in Boston. And she's worked at UCSF since finishing her training in 2005. And I actually did a UCF residency at Santa Rosa in a family practice, so we have that in common. So welcome, Heather. Thank you so much for having me. All right. So I did a little bit of a clip on PCOS on my podcast, and it caused a lot of discussion and a lot of controversy, and everybody's got opinions. And like many things in medicine and in life, it's not black and white. There's many layers to this conversation, which we couldn't really address in that short clip. And I discussed something that is a huge factor in women's health, which is insulin resistance and weight gain, which often interfere with hormonal function. And yet, you know, that's only one piece of the puzzle.

It's not all about diet. And we're going to talk about PCOS in general. We're going to talk about what factors cause it, how to treat it, and how obviously also nutrition plays a role. But I'm really, really excited to talk to you about it. And let's just get started by talking about how common this is. You know, about 5% to 10% of women who are of childbearing age have this, and it's a really important cause of infertility. Walter Willett at Harvard wrote a book called The Fertility Diet, which was a lot about this.

It's also the most common hormonal disorder in premenopausal women, yet often the cause of it and treating it is not well understood by most doctors. So, you know, tell us a little bit how, how PCS has sort of been the sort of neglected stepchild of medicine and OBGYN and how we can kind of correct that. Yeah, I think it's a great question. I mean, I think it's a somewhat complicated disorder in the sense that it brings in a lot of different systems and a lot of different kind of ramifications that cross a bunch of disciplines. And I think the way medicine sort of is practiced in the United States these days is it's very siloed. And there's sort of certain doctors that take care of one little specialty. And PCOS has kind of fallen through

the cracks in many ways of all of those specialties in my view. I mean, so PCOS really brings in a hormonal component. It brings in a gynecologic and reproductive component. It brings in a metabolic component. And all of those things really weave together, not only in the pathophysiology, but also in the outcomes. And there's not really one specialty that really adequately covers those. OBGYNs maybe know some of the reproductive piece, but they're not as always up to speed on that metabolic. Endocrinologists might know a little bit more about the metabolic piece, but they're a little

nervous about what's going on with the reproductive side. So as a result, I think a lot of patients with PCOS sort of end up getting bounced around to different doctors, never really getting great explanations about what's going on with them and what are sort of some appropriate treatment pathways for them. It's so true. And I think often doctors aren't great at diagnosing it. And maybe you can take us through what are the key symptoms that you would look for in a patient who came to see you with PCOS? Yeah. So first of all, just to echo what you said, there's been some studies, international studies that have shown that the common average number of physicians or providers that people with PCOS see before getting a diagnosis is something like on average of four. So people are definitely wandering around trying to get someone to really help them.

But there is an international kind of consensus at this point around the way that we diagnose PCOS. And this has sort of been developed and sort of hammered out over the past 20 years. And it looks for three things. And you really just need two of those things. So the first is irregular cycles or what or mean like long cycles going every 40 days or fewer than eight periods a year. The second component is hyperandrogenism. So either clinical hyperandrogenism, meaning hirsutism and acne or bio- And hair growth, hair growth on your face.

Mm-hmm. Or a blood test is showing elevated androgens. And then the third component is features of polycystic ovaries on an ultrasound. And so those are the three components and you just need two. And so if I have someone come in to me looking to see if they, if the things that are going on with them sort of fit within the box of PCOS, those are the three components that I'm going to look at. And typically when I was in medical school, I remember learning that, you know, this is typically overweight women. And that's not always the case. I actually have had many patients who are thin,

who have PCOS and struggle with acne and hair loss and irregular cycles. So, you know, can you kind of take us down the road of, you know, what is it besides the weight that can cause this? What are the causes? Obviously, part of it can be insulin resistance and diet and sugar and starch, but it's not the only thing. So what are the causes of PCOS? Well, I mean, I think it's a little bit of a million dollar question. There's

a lot of research trying to answer that question. It's also a very heterogeneous disorder. So I don't know if there's one thing that causes it for everybody. But I think we do know that a major underlying factor is the hyperandrogenism that is, you know, that there's elevated androgens starting at puberty, and that that may then sort of underlie a lot of the phenomena that comes across with women. So one of the things we know is that there's an increase in visceral adiposity, or sort of belly fat, belly fat, that happens that we know is more common in general with men. But this is what happened when you have elevated androgens in a woman, especially starting at puberty, they lay down fat in that area. And that in women causes a lot of inflammation,

that then can really be a setup for insulin resistance. So there may be sort of a pathway where you see hyperandrogenism then in many people also leading to the insulin resistance. Then you start to get into a little bit of a vicious cycle because the insulin resistance in and of itself causes some weight gain, but it also can drive androgen production from the ovaries. So starting at puberty, a lot of these people get into a little bit of a vicious cycle. It's very hard, if not impossible. What starts the high levels of androgens or the male hormones, testosterone and others? So it's a debated issue. I think that there's one component, maybe that there's just an, if you look at some of the enzymes in the ovary and in the adrenal

gland, there's just sort of an overactivity of those enzymes in the ovary and in the adrenal gland, there's just sort of an overactivity of those enzymes in the ovary and in the adrenal gland. So there's some thought that it's just an intrinsic overproduction of androgens. There's also, at least in some patients, we think just from the get-go, they have an increased LH secretion from their pituitary. This is a hormone that drives androgen production from the ovary. And so they may be set up by that even sort of in utero to have increased LH secretion. So we don't really know, but we know that at puberty, immediately, these girls will often start to have much higher androgen levels than their peers. And then that sort of lays the groundwork for a sequence of events to happen. Yeah. One of the things that's sort of lays the groundwork for a sequence of events to happen. Yeah. You know, one of the

things that's sort of read a lot about is the role of endocrine disruptors in our health. And endocrine disruptors are environmental chemicals. Years ago, I read a book called Our Stolen Future by Theo Colburn. It was kind of like the silent spring of its time where she mapped out the ways in which environmental chemicals affect all kinds of reproductive functions. And whether it's determining sex or determining risk of cancers or infertility in animals and human models. How do you think environmental toxins play a role in the uptick of what seems like this increasing phenomena of endocrine disorders in women? I think it's hard to know how much they are causative in terms of PCOS. I think it's possible. I certainly think it's definitely possible that they may exacerbate certain

elements of it by interfering with hormonal function. But, you know, PCOS has been around for a long time, as far as we can tell. It seems to be present at a pretty standard or set prevalence across many different countries and parts of the world, which somewhat argues against it being truly environmental. Now, I do think that certain environmental endocrine disruptors or just societal patterns, especially diet, can definitely exacerbate the way PCOS gets manifest. So if you look at PCOS patients in Europe, especially 10 or 20 years ago, or in China, they tended to be much more lean than patients in the United States and have much less sort of inflammation and insulin resistance. And so there's certainly, if you have a PCOS phenotype and you put it in an environment

where there is calorie excess or limited physical activity, you are going to see potentially, at least in some patients, an exacerbation of the symptoms. But I don't know that you, I don't know that in my view and from what I understand about this syndrome, I don't think it's necessarily caused by our lifestyle. And the nutritional part, what role does that play? Because, you know, I've had many patients with infertility who, when we address the starch and sugar in their diet and treat the insulin resistance, they get better. And I mean, I had a very close relative who had obesity and pretty severe PCOS and hirsutism and acne.

And we radically changed her diet and she was able to get pregnant and have a baby. So can you talk about the nutritional aspects of PCOS and how that plays a role and where it doesn't play a role? Yeah. I mean, I think for sure there's evidence that in some people with PCOS, especially if there's evidence of insulin resistance or if there's evidence of glucose intolerance, that they're clearly have entered a phase where they're not processing glucose well, that if you act to correct that through diet and through exercise and you reduce the degree of insulin resistance, you reduce the degree of adiposity, that in some of those patients, they will ovulate more regularly, they will have more successful, more healthy pregnancies.

So that is certainly something that I think I always talk to my patients about when I see them, if I think that there's a window for that. There are patients, however, you know, especially when you look at some of the lean PCOS patients or patients from the point of adolescence have never had regular cycles. You know, I think it's a lot to say, oh, just change your diet, you're going to start ovulating. I don't think that's always the case. So I think every patient's a little different, and you need to really look at it. The what I usually look at, though, is I want to say, how are we going to get you as healthy as possible for pregnancy, and maybe that will help you get pregnant. Maybe it won't, but I want to get you as healthy as you can for pregnancy and get, you know, your insulin

resistance as much as possible under control. Yeah. How about the microbiome? Because, you know, this is sort of the era of the microbiome and before, you know, nobody ever thought that the gut played a role in hormones or endocrine health or infertility, but now it's clear that it's sort of got its finger in everywhere. And we see studies, for example, on breast cancer. Women who take antibiotics have high risk of breast cancer. We know that the microbiome plays a big role in hormone metabolism. So can you talk about what you're learning about that and how that plays a role and how you approach that? Well, I think that there's definitely some really interesting research going on around microbiome and PCOS. And there's this idea that there may be a more sort of inflammatory microbiome that

leads to more inflammation in the body. And we know that many patients with PCOS just have high rates of inflammation that is detectable. And if you look at sort of blood markers or just even at the insulin resistance. So this is in many ways an inflammatory disorder. And so there is research going into like how much of that might be driven by the microbiome. And, you know, that's a little outside my scope and maybe more your scope, exactly how that may be the case. But I think it's definitely a really interesting area for us to try to understand more, you know, how much that may be sort of setting people up to have PCOS sort of evolve at adolescence and really to

exacerbate the metabolic phenotype. Yeah, well, you said something super interesting about the inflammation because inflammation, independent of its source, seems to be a trigger for all kinds of things, obviously chronic disease in many ways, but for these hormonal disorders. So can you talk and maybe unpack a little bit more about the link between inflammation and endocrine disorders, and in particular PCOS? Well, I think for sure we know that inflammation may have some direct effect on ovarian dysfunction. So there are some studies showing that if you treat inflammation, you can improve sort of ovulation to some degree in the ovary. So there may be a direct effect of inflammation on the ovary.

There's also a path where inflammation does drive up insulin resistance. And that's through sort of TNF-alpha and other cytokines that are thought to interfere with insulin action. And we know that insulin resistance really drives androgen production from the ovary, at least in patients with PCOS. So there's definitely a metabolic sort of driver of the hyperandrogenism and hormonal dysfunction and anovulatory sort of status that we do see. And then we also know that that inflammation in and of itself has really important downstream consequences, not only in terms of cardiovascular disease, but there's more and more of a thought around depression and cognition that may be impacted by inflammation. So I do think it's really an

important piece of this disorder that we want to try to get a handle on and try to treat. It's so important. And it's so many causes of inflammation. It can be environmental toxins. It can be the microbiome. It can be inflammatory foods. I mean, there's so many factors that we know that are driving inflammation in our society that are just getting worse and worse. And so it might be not one thing, it may be so many different things. Hey everyone, it's Dr. Mark. It's hard to overstate how important magnesium is for all aspects of our health. There is a long list of symptoms and diseases that can be treated and even cured with magnesium. In fact, way back when I was an emergency room physician, magnesium was a critical element of our care. We used it to treat

all kinds of conditions from arrhythmia to constipation to preeclampsia. It's really essential to our health and well-being, and yet over 80% of the population doesn't get the magnesium they need on a regular basis. Now, this is a problem because magnesium deficiency can increase your risk of all diseases and keep you from performing optimally. But even more critically, there's not just one type of magnesium. There are seven different types that we need in our diet to ensure both our health and our vitality remain strong. I'm normally a big advocate of getting as many nutrients as you can through a well-balanced diet, but in this case, it's almost impossible to get enough magnesium intake through your food alone because our soil is silverworked and mineral depleted. Fortunately, Bioptimizers has the solution. Their magnesium breakthrough supplement is the only product on

the market with all seven types of magnesium and especially formulated to reach every tissue in your body to provide maximum health benefits. Bioptimizers Magnesium Breakthrough gives you access to the full spectrum of magnesium, which can dramatically improve your overall health from reducing stress to improving sleep and boosting your energy levels. For a limited time, Bioptimizers is offering additional bonus gifts of up to $79 to the next 1,000 customers or while supplies last.

week's episode of The Doctor's Pharmacy. Can you talk about the difference between the patients you see with PCOS who would be the typical ones we learn about in medical school are overweight, they have acne, hair loss on their head, facial hair, irregular periods, infertility, versus the ones who are thin and exercise and don't seem to have any weight issues. Is there a different subtype? Are these the same kind of condition how are they different i mean i i think that they're they're probably subtypes i mean i think that this is a psoas is i think a very heterogeneous disorder it's really just a syndrome right it's a collection

of things that kind of go together and sort of have somewhat of a shared pathophysiology but it's not like you know if you think about something like hypothyroidism, which is very much, you know, it's like, your thyroid gland isn't functioning, you're going to have this, you fix this, you know, translates PCOS is, is messier. And so yeah, so the patient, there is a lean phenotype, we call it lean PCOS. And it's often quite different than the obese PCOS. Some of the things that may be similar is the lack of ovulation, the need for help with fertility care. So that may be a constant. The other thing that may be a constant is trouble with elevated androgens. So hair growth on the face, acne, that can still manifest in lean PCOS. But, you know, PCOS patients are lucky in that they

are often not quite as much struggling with some of the metabolic features. Although in studies where they measure insulin resistance very closely and very carefully in research settings in even lean PCOS, they are more insulin resistant than lean non-PCOS. So there is still an insulin resistance piece there, but it's sort of either genetically not as sort of exacerbated, or maybe that that person has just a very healthy lifestyle and they're able to keep a lot of it at bay. And what, you know, one of the, one of the consequences for people people if they have PCOS? What should they be aware of? What should they know about in terms of their own health and long-term risks? I mean, it's, I think, a very multifaceted disorder. There's generally sort of five or six

things that I go through with patients with PCOS. So the first is menstrual cycle control. So it's important for people to have somewhat regular menstrual cycles or to have at least some sort of progesterone in their system to prevent overgrowth of the lining. There's the management of their skin or cutaneous findings with PCOS. So how can they manage their hair growth? There's fertility concerns. There's metabolic concerns, especially things like future diabetes, future cardiovascular disease. And then there's a lot of mental health disorders that we see in PCOS. Really? So there's a high rate of depression. Yep.

And do you think it's a cause or a consequence of it? I mean, it's something I've been really interested in researching. One of the things we've shown in some of our work has been a very strong correlation between insulin resistance, actually, and depression. And even when you control for body weight, and even when you control for patients that insulin resistance in and of itself may be contributing to depression. That's something we see in the diabetes literature as well. That's a frightening idea because when you look at the metabolic health of America, I think a new data came out from Tufts that 93.2% of Americans are metabolically unhealthy, meaning they have some degree of insulin resistance. And we also see this sort of epidemic of mental health disorders and depression. And I don't think people realize that, you know, sugar and starch and processed foods is driving not only weight issues, but also mental health issues. Yeah. I think it's, to me, one of the more profound connections and profound concerns. And I think it's unfortunate because in some ways that depression

can often make it harder to address the diet and the exercise. You know, if you're feeling depressed, you're not in the most ideal state to sort of make those important lifestyle changes. So I think it's important that we take into consideration what's happening in terms of a mental health milieu for patients with PCOS and take that into account when we kind of talk to them about treatment, because that's an important component, I think, that needs to be addressed if we want them to make those important lifestyle changes. Yeah, for sure. So when you see someone with this problem, what's your general therapeutic approach? How do you treat these patients? What are the ways that we sort of can help them have

regular cycles to where their acne, their hair growth, their hair loss? And, you know, I think you mentioned something really important, which is that you want them to have progesterone, which is sort of the antidote to this overbuilt up of estrogens that happens in these patients. And they don't ovulate every cycle, so they don't make progesterone, which is what you do when you ovulate. So can you talk about what are the kind of therapeutic approaches and how do we potentially use progesterone or other therapies like that? I mean, so I think in terms of therapeutic approaches with PCOS, it's always hard because I think it to some degree depends on what is their goal.

Like, what are they trying to achieve? You know, are they trying to get pregnant at this moment or not? But in terms of the menstrual, let's say it's someone who's like 22 and she's coming in because she's only having three periods a year. And when she does, it means they don't get progesterone. And that means that estrogen is going to cause over time buildup of the uterine lining, which can lead to very heavy menstrual cycles, but it also is a risk factor for endometrial cancer over time. So it is important that patients with PCOS get some sort of progesterone exposure. And that can be in the form of oral contraceptives, it can be in the form of bioidentical progesterone being taken cyclically, it can be in the form of an IUD that releases progesterone. I mean, so there's a lot of ways

to do it. But if I have a patient who's having three cycles a year or something like that, that's an important conversation that I'm going to have is like, look, we need to figure out some way for you to have progesterone because it's not healthy for your uterus to not have that progesterone over time. So that's helpful. And then what else do you do to help with their, so besides bioidentical progesterone, what other kind of therapies support these patients? In terms of their other symptoms? Yeah. How do you deal with the hair loss or how do you deal with the acne or how do you deal with the hair loss or how do you deal with the acne or how do you deal with the the the irregular cycles what hormonal therapies are used yeah yeah so i think the irregular cycles would be addressed through some form of progesterone but the hair loss or hair growth or acne those skin findings um are not our most or best address, quite honestly,

by being on something like a birth control pill, because the and you're going to suppress the sort of stimulation of the ovary that's driving up the androgens. And you're also going to increase sex hormone binding globulin, which is a protein from the liver that really soaks up that extra androgen. So that's honestly the best way to get benefit in terms of the, especially hirsutism and acne. And then sometimes we'll even use medications that will block androgen action like spironolactone. Now I do have patients who don't want to go on those medications and feel like that's not fixing the underlying problem and it's just patching it or they don't want to be on the pill for any reason. So that tool is not always the ideal tool for our patients,

but it is certainly one that I would discuss. And what role do you see as diet? Is it a strong lever for changing these patients' reproductive health and their cycles and their symptoms? I mean, if you basically put people on a low-starved sugar sort of diet that treats the insulin resistance, do you see big changes in their clinical picture? I think in some, for sure. And I think, you know, there haven't been great studies on this. There's been a few. I do think that if patients are able to maintain a very low carb diet,

sort of a ketogenic diet, they will be able to really manage their insulin resistance. And that really takes away one of the sort of drivers or triggers or things that's really exacerbating their sort of phenotype or their symptoms. So if you are able to get the patient to sort of embrace that approach, I do think that you will see that often patients will see benefits. I think it's something that has to be monitored. I don't think all patients will suddenly start having regular cycles and their hair growth isn't going to suddenly go away. But some patients may have more cycles. Some patients may be able to conceive that way on their own without fertility treatment. But others will not.

So I think it's something that I try to discuss as an option. But I think I shy away from saying, like, here's a way to fix this. Because I think, in all honesty, it doesn't fix it for some patients. And that's really frustrating if they feel like they're sort of somehow failing well that sort of speaks to how little we know right because in some patients it works in some patients it doesn't you don't really know which one's which right and it's really about personalizing care yeah so I think it's I think it's a challenge and I do think it's one I mean PCOS is definitely a disorder that just takes a lot of personalization because it's such a diverse heterogeneous disorder. The concerns and the goals are often very diverse. So I think no patient and no treatment plan, quite honestly, is exactly the

same. And, you know, years ago, I read an article in the New England Journal of Medicine about D-chiroinositol and PCOS, which is a derivative of B vitamin. It seemed very promising. It kind of seemed to fall off the radar. What is the role of that and or other supplements in the treatment of PCOS? I mean, I think it's still on the radar in the sense that people are using it. People are trying to study it. I think that there's been sort of mixed results in the studies that are out there. I think we're somewhat hampered by the fact that people are taking it in different sort of formulations and different ratios and different dosages, which makes it a little hard to sort

of figure out whether it's working. I will say anecdotally, I do have patients who seem to become more regular in their cycling when they're taking it. And they find it easier to take than other medications that might do that, like metformin. So I think that there's potential there. And I think there is a pretty good study being run right now that hopefully will give us some answers. So I definitely think it's still on the radar. Yeah. And what about other supplements? Do you ever prescribe other things to help with nutrition or with insulin resistance or any of the symptoms? Like for example, saw palmetto is something I often use. It's a five alpha reductase inhibitor, which is like what you use for

inhibiting like androgen production for the prostate and for men, for example, like ProScar. Yeah. Or finasteride. I have had patients taking that. I'm curious to hear how much you see as a benefit. Like do you see patients really come back and say it worked or? Yeah, it really depends on the individual, right?

So someone's like, oh yeah, they notice their acne better or it's like spironolactone it's similar similar effect to that but it's an herbal formula i mean it's used for men's prostate so it's a little weird to give it to women but i said well don't worry about the name of the product that says prostate on it but you didn't worry about the mechanism of action of the herb or you know um and i wonder about you know omega-3s or vitamin D or. Yeah. So, I mean, I feel like vitamin D is really important. I definitely, we check vitamin D on all of our patients coming in. We definitely find many, many of our patients are deficient. So I, I do try to get patients to sort of really replete their levels of vitamin D.

Beyond that though, I would just say say we really just take a pretty common sense approach to the diet and trying to like work with, you know, where that patient is at that time. So like some people's diet is terrible and there's like a lot of room for improvement. Some people are already doing a lot of the right things and you're just tweaking it. I find one of the big things that's missing is exercise. And some of our studies have shown such significant benefits for patients who are able to sort of keep that as part of their life. You know, we've looked at sort of our patients who exercise and our patients who don't. And it's dramatic, I think, how much sort of metabolic benefit patients can get if they can be active on a daily basis.

Yeah, that's such a key thing. So tell us about the mechanism of action. You know, you've done a lot of research on this, but how does this work? You know, I think there's the main mechanism of action, and, you know, it's probably deeper than this. But we know that just by increasing muscle mass, you're going to sort of improve insulin signaling, you're going to improve glucose uptake. And so there just seems to be a direct correlation with insulin resistance and exercise that I think is profound. Some of my patients will come back after exercising, they'll say I didn't really lose that much weight, and they'll be very frustrated about

that. But if you look at their numbers, you'll see that they've, you know, their insulin levels have dropped, their glucose levels have dropped. And so sometimes for me, it's about really showing them like you are healthier, you probably gained some muscle, and that's why it's not a different number on the scale. I think that's one thing. But I also think getting back to the depression piece, like there's a, you know, really often significant improvement in sort of self acceptance and in mood that happens with exercise, that then I think can translate into sort of self-acceptance and in mood that happens with exercise that then I think can translate into sort of more energy for all sorts of lifestyle improvements. And then that ultimately translates to insulin resistance improvements. Yeah, for sure. So you've done a

lot of research. What are you most excited about that you're working on in terms of the research on this and endocrinology in general and PCOS and fertility? I mean, I think for me, my biggest interest has been around the mood. I've been interested in looking at cognition and how it's impacted in PCOS. And then another area that I've been really interested in doing more work in, and we have a small pilot study starting is on sleep. They think sleep is often very disrupted in people with PCOS. We know there's a high rate of sleep apnea, but even beyond that, other sleep disorders. And I also think sleep is like a really key thing that can help with insulin resistance. So I guess I'm really interested in a lot of these things around the edges of PCOS that we can sort of fix to sort of improve quality of life. I don't know that I feel like I'm going to necessarily cure PCOS or make it not ever be a thing.

But I think we can do a lot to improve the experience of having it. So would you say if you fix insulin resistance that PCOS gets resolved? Or are there other factors that keep it going forward? In other words, if you've got someone's insulin perfect and you've got their blood sugar normal and you've got their lipid profile normal through diet, lifestyle, whatever, would that kind of eliminate PCOS? Or is there still factors that are driving PCOS beyond insulin resistance? I think there's still factors driving it, at least in most, you know, to the extent that it's truly a disorder of elevated androgens.

You're not going to completely take that away by fixing the insulin resistance. You are going to minimize a lot of the symptoms. You're going to potentially make it a very manageable disorder by managing the insulin resistance. You're going to potentially make it a very manageable disorder by managing the insulin resistance. You're going to make it so it's not such a burden. But I don't know that you sort of can wave a wand and it's no longer there. I think that sort of intrinsic physiology that person was born with is still there. You're just sort of helping them manage it better. Do you think it's partly genetic? I mean, this is like a huge kind of controversy as well in the field. So like there was a lot

of research that went on trying to look at, you know, these GWAS studies, looking at all of these genes. People had a lot of excitement about finding the PCOS genes. And ultimately, they did not find very much. I mean, they found some genes that maybe explain like 10%. So, you know, there's some thought now that it may have to do with sort of a, you know, basically like epigenetic phenomenon where maybe the maternal androgen levels may be driving or causing sort of changes in the fetus in utero that then set the fetus up to sort of have a PCOS phenotype. And we know that that's sort of true in animal models that you can induce PCOS by maternal androgen. So to what extent that explains

it in humans, we don't know. Maybe there's this microbiome theory, you know, so I don't know maybe there's this microbiome theory you know so i i don't know that we know i think that there's probably multiple pieces probably multiple genes and multiple environmental factors that maybe set it up initially and then you know once it's in place it kind of self perpetuates yeah and it's such a bit such a common problem like we talked about earlier it's like five to ten percent of women at some level and i mean I mean, that's a big chunk of the population. So you're probably very busy, my guess. You also created a platform, which is kind of exciting, which is an advisory platform, which is an all-in-one virtual care platform for people with PCOS called Alara Health. How does that work? And what does it provide? And how do people get supported through this process? Because a lot of the stuff that has to be done is behavior change, lifestyle change, and it's not just taking a pill. Yeah, exactly. A lot of times it's having a partner that you work with over time that can

really sort of kind of take you step by step through the improvements you need to make. But yeah, so Alara is, you know, it's, I think it's very much similar to what we do in our multidisciplinary clinic, but it's taking it, you know, to a virtual platform and making it available to people sort of all over the country. And so as we talked about, I think PCOS sort of falls through the cracks and there's not a lot of providers who really, you know, own this disorder. So I was really excited when I heard about Alara as just something that could sort of bring, I think, an evidence-based approach to PCOS that incorporates things like nutrition and mental health support and can do it sort of virtually

and can do it over time in a way that really sort of partners with women and so and just improves access you know because I think that there's a lot of people with PCOS out there that don't feel like they're getting the care they need so oh millions clearly millions of people have this right so exactly and you know I mean there's a few PCOS clinics in a few cities and there's you know, I mean, there's a few in a few cities and there's, you know, there's always going to be a few practitioners who really own it and understand it and want to talk about it, but many practitioners don't. And so this is a way I think to give access to more people to sort of feel like they have a home for their PCOS, feel like someone who understands PCOS

can sort of walk them through the ways to improve their quality of life or achieve the goals that they want to achieve. So if you were sort of, you know, this is really great because I think it offers a forum for people to get connected to other people who have this issue. It offers guidance on how to do the things you need to do to kind of reset your system and move yourself down the path of health. From the perspective of, you know, an expert in this field, when you see a patient, you know, what sort of, just kind of take us through maybe a case before we close of what you see, maybe a few cases of how they presented, what were the different kind of findings and what were the approaches that you used and how did you

sort of move them down the path to health? Okay. I mean, I think I've always found that partnering with patients and being able to sort of see them somewhat frequently has been a really big sort of helpful way to kind of help them make the improvements they want to make. I think an example might be, let's say, a 22-year-old that I originally saw who came in, didn't know why she wasn't having periods, didn't know why she had excessive hair growth and acne. And we did a workup. We identified PCOS. We did a lot of education around PCOS. At that time, it made sense for this patient to go on birth control pills to sort of manage a lot of the symptoms. And so she went on birth control pills for a few years. But then several years later, came back, didn't want to be on birth control pills anymore,

had gone off, had gained some weight, was thinking about starting a family soon. So at that point, you know, I ran some metabolic tests and found that she was insulin resistant and wanted her to work on that before starting to try to conceive. And so at that point, we had her sort of work with a nutritionist or I worked with her and had her start exercising. That would be sort of the program I would want that patient on at that time to sort of optimize her health before getting ready to conceive. And then, you know, ideally those things have been improved and then it would be time to sort of think about the different ways to help someone get pregnant. But as you said, some patients through the use of

sort of diet exercise or other ways to improve insulin resistance may start ovulating on their own. And in those cases, they are very much capable of conceiving. PCOS is not a fertility diagnosis. It's just a disorder of ovulation. So many of those patients may be able to conceive on their own. But if not, you know, if they're not ovulating regularly enough, despite doing all those right things, then, you know, there are other ways that we can help people get pregnant by, you know, boosting ovulation through medication. That's true. Amazing. You know, one of the things you said I just want to touch on because it's not really common is measuring insulin. Now, I never learned to do that in medical school. I almost never see insulin measured on any lab panels that patients come to with from other physicians. And it's something you measure. I've been measuring

it for almost 30 years. And I'm curious about how do you diagnose insulin resistance? Because if you look at the data on our metabolic health, I mean, 90% of Americans are metabolic unhealthy. And that, to some degree, is a degree of insulin resistance. And yet, it's the most common disorder in the world right now. And yet, most doctors don't know how to diagnose it. So how do you approach diagnosing someone with insulin resistance? Yeah. I mean, we, I, you know, we take a deep dive, I think, into people's metabolic health

in ways that a lot of doctors maybe don't. I, you know, we measure, I like to measure fasting insulin and fasting glucose. And, you know, the simplest way to diagnose insulin resistance there would be to calculate a home IR, which is a plug two numbers in basically to a formula and you can get a home IR. And if it's over 2.1, there's some degree of insulin resistance. Even simpler, though, is just looking at the fasting insulin. I think you're in the double digits. You already know you're probably a little insulin resistant.

And many of our patients with PCOS are much higher than that. We also do a glucose tolerance test, which is another test I think a lot of doctors don't do, but I think it's also really helpful. A lot of patients with PCOS, their fasting glucose is going to be relatively normal, but if you give them that 75 grams of sugar, two hours later, their sugar is still really high. So that's another way of sort of, I mean, it's not quite specifically insulin resistance, but essentially it is because you're basically showing this patient is not able to dispose of glucose.

Do you measure insulin too on that test? To be honest, I do. I mean, I think that's, it's almost more of like research kind of like, I don't know that we have like really validated measures or what's a firm cutoff there. But I will say in many of our patients with PCOS, we see very, very high two hour numbers, sometimes like 300. And to me, I like to see that because it really tells me kind of what I'm working with and how sort of entrenched that grievance and resistance is. Yeah, that's such an important observation.

I had a patient once who was a typical apple shape, very central obesity, very overweight. And I was shocked because her hemoglobin A1C, which her average blood sugar was normal, her fasting blood sugar was perfect in the 90s. And I said, well, let's just do a glucose tolerance test. And we measured insulin and we measured glucose. And it was shocking. Her blood sugar never budged. I said, well, let's just do a glucose tolerance test. And we measured insulin and we measured glucose. And it was shocking. Her blood sugar never budged.

I mean, it went from like maybe 90 to 110. It was perfect at one in two hours. But her insulin was high fasting, like probably 20 or 30, but it went up to like 200 or 300. And I was like, holy crap. This person, clearly, when you look at her, was insulin resistant, but her blood sugar and he was normal, which is what most doctors will check. So you'll miss so much if you don't look at the insulin also. So I think that's a real take home for people is ask your doctor to check your insulin,

at least fasting. And you said it double digits. Now, if you look at the reference range on insulin in most labs, it's like 15 or something or even more. That's not optimal. That's probably like less than five is good. Five to 10 is maybe okay. Over 10, no way. So I think we just have to kind of get better at diagnosing this as a medical profession because we're really bad at it. It's such a key driver of not just infertility and hormonal disorders,

but obviously diabetes and heart disease and cancer and dementia. So it's just really across the board, one of our biggest problems. Yeah. I mean, I think we know that just even those high levels of insulin, hyperinsulinemia, I mean, clearly is driving some of the problems in PCOS, but there's, thoughts of how much that might drive cancer growth and things like that. And if you see that patients underneath the surface, it's almost like you're seeing how things are playing out, you see that their insulin are sky high, two hours after glucose, which is, you know, happening to that person every single day when they have glucose, you know, you're getting almost like this sort

of underneath the hood, look at what's going on in their physiology and you can see where that's going to go. It's going to not go well. And so that's, to me, that's often like a really great way to like, look at those numbers with a patient and explain that to them. And often it can be really motivating for patients when they see that to make the changes that they want to make. Yeah, that's great. I mean, there's so much new technology, the continuous glucose monitors that are emerging. I met somebody who's developing this company, which is like a bandaid that measures your blood sugar. It's sort of a new tech thing. I don't know how it works, some transdermal way to measure. So I think people are going to be getting more and more able to understand their health in real time. And I think the work you're doing is so important.

So I really appreciate what you're doing. And I think it's very hopeful because from listening to it, it's really clear that you can make a lot of progress with both the condition and the symptoms, both in improving fertility, regular cycles, improving acne, hair loss, and things that really are distressing for women. So I think it's a very hopeful conversation. And it's great that you're looking at all the intersectionality of inflammation and the microbiome and environmental toxins and diet and all these things that often are kind of stepchildren of medicine, but actually play a big role in all these disorders, whether we like it or not. Thank you so much for what you do and I look forward to keep, keep a track of your work.
