We are in the middle of an alarming trend. More and more women are being diagnosed with polycystic ovarian syndrome (PCOS), an endocrine disorder that causes irregular periods, acne, hair loss, and hirsutism.
The disorder is not new, but it is increasing at a dizzying rate. Two decades ago, PCOS was infrequent amongst my patients. Today, I see it all the time. Polycystic ovaries are estimated to now affect close to one in five women, with an even higher incidence in teenagers. What is going on?
A big part of the problem is insulin resistance which is is the hallmark condition of our modern age, affecting 1 in 4 adults. Insulin resistance is the result of too much sugar (concentrated fructose) in our diet, as well as smoking, obesity, trans fat, stress, and environmental toxins. Untreated, insulin resistance can lead to diabetes and cardiovascular disease.
Insulin resistance is estimated to affect between 50-70% of PCOS-sufferers , and is generally understood to be a major contributing cause of the condition . Excess insulin causes polycystic ovaries because it impairs ovulation and stimulates the ovaries to make testosterone instead of estrogen.
We have an epidemic of insulin resistance, so it makes sense that we also have an epidemic of PCOS. Except that not all PCOS sufferers have insulin resistance, so what else is going on?
Misdiagnosis by Ultrasound
Proper diagnosis of PCOS requires clinical evidence such as irregular periods, combined with a blood test that shows high androgens. There may or may not also be the ultrasound finding of polycystic ovaries, but that finding alone cannot be used to diagnose PCOS. Why? Because polycystic ovaries occur in up to 25% of normal women, and also in many women on on the birth control pill .
Would a family doctor or OB/GYN really attach the label of PCOS to a normal woman solely based on one ultrasound finding? Sadly, the answer is Yes in many cases, and that can lead to a lot of unnecessary confusion and heartache. I almost never accept a diagnosis of PCOS at face value. Instead, I order extra blood tests form my patients to confirm that they do have high androgens.
Fortunately, there are calls to rename the condition, and to re-educate doctors about the relevance of the polycystic finding. According to Dr. Robert A. Rizza from the Mayo Clinic:
“[The name PCOS]..focuses on a criteria—namely the polycystic ovarian morphology—that is neither necessary nor sufficient to diagnose the syndrome. It is time to assign a name that reflects the complex metabolic, hypothalamic, pituitary, ovarian, and adrenal interactions that characterize PCOS.” 
There is one more reason for the increasing incidence of PCOS: The Birth Control Pill. In my clinic, I speak to so many women who simply cannot get their periods going again after stopping the Pill. Some of them did not have regular periods before taking the Pill, so, in their case, stopping the Pill has merely unmasked a preexisting problem. Then there are the women who did have regular periods before the Pill, but now they’re gone. For these women, the Pill seems to be a clear cause of PCOS and hypothalamic amenorrhea.
We don’t yet know exactly how the Pill causes PCOS because that research has not yet been done. We do know that the Pill causes insulin resistance, which in turn, causes PCOS . We also know that the Pill suppresses the pituitary-ovarian communication, which of course it’s designed to do, but that suppression is supposed to be temporary. It’s supposed to be temporary, but some women experience an ongoing elevation of the pituitary hormone LH (even in the absence of other PCOS markers such as insulin and androgens). Without treatment, post-Pill LH elevation can persist for months or even years after stopping the Pill.
What to do about PCOS
If you or your patient has been diagnosed with PCOS, then first find out if it was diagnosed by ultrasound alone. If it was, then the PCOS diagnosis is not certain. Ask for further blood testing to see if there are high androgens, and most importantly: If there is insulin resistance.
When it can be determined that insulin resistance is the cause of PCOS, the best treatment is to eliminate concentrated sugar (desserts) from the diet, and also to supplement nutrients (such as magnesium) that improve insulin sensitivity.
When insulin resistance is not the cause of PCOS, things get a little more complicated. Non-insulin-resistant PCOS is often the result of the Pill (as discussed above), but it can also be the result of other underlying health issues such as chronic inflammation. I explore the natural treatment of PCOS in my new book Period Repair Manual.

I believe the over use of plastic, which is made of chemicals that imitate hormones and petroleum is the root cause. We run around being over-the-top germaphobes but never question the health effects of the most pervasive material used in our modern world. It was not until late 1970s that plastic started to used so frequently. Now almost every product including the threads that make our clothing are made of plastic. We have ruined our above ground resources, yet our social norms make us want to own more stuff giving the oil industry even more power and need in our society. There is a small movement of people who are trying to live plastic free called Zero Waste. Look it up. Look up Beth Terry book Plastic -Free Living. The environmental consequences are obvious. As 1/3 of all plastic gets into our water system and eventually into our oceans. The plant-life in oceans provides 70 percent of our oxygen, the more plastic you put into it the more we chocking off our oxygen supply… But back to our personal health. Definitely this synthetic material is dangerous to our personal doubt. By the time anyone has the time and money to prove how the plastic industry, which is the oil industry causes many of our modern ills it will be too late. Again, I will be the only one on earth to say this but plastic is more dangerous than germs. Plastic causes cancer and infertility and God knows what else. Waiting for the medical field to make connection, but habitability of this earth will be gone before that.
