What is PCOS?

Polycystic ovarian syndrome (PCOS) is a common hormonal condition that affects women of childbearing age. In PCOS, the ovaries form numerous small follicles that do contain eggs, but the eggs don’t mature; thus, the eggs aren’t released. The first symptom of PCOS might be abnormal menstrual cycles that can manifest in several ways:

  • Complete absence of periods (amenorrhea)
  • Infrequent periods (oligomenorrhea)
  • Longer than normal menstrual cycles – for example, a cycle lasts 38 days instead of 28 days
  • Abnormally heavy periods

The numerous undeveloped follicles result in infrequent or no ovulation and contribute to difficulty conceiving without medical intervention. Women with PCOS typically have elevated androgen hormones, such as testosterone. These hormone elevations can result in acne, hirsutism, and male-pattern baldness.

PCOS by the numbers

  • As many as 1 in 10 U.S. women of childbearing age (ages 15-50) has PCOS.
  • PCOS is one of the most common, but treatable, causes of infertility.
  • PCOS is one of the most common endocrine disorders in women.
  • And here’s the clincher – half of women with PCOS are undiagnosed.

What are other health concerns associated with PCOS?

Although infertility is often the cause for a woman to seek medical advice, a woman with PCOS is also at higher risk for other health concerns – and, in some cases, it’s difficult to determine whether the condition is a result of or a cause of PCOS. Associated conditions include:

  • Difficulty managing weight. Excess weight can be a cause or an effect of PCOS. Sometimes PCOS symptoms don’t manifest until a woman gains significant weight. On the other hand, women with PCOS tend to gain weight easily. The extra weight can contribute to other health issues.
  • Metabolic syndrome. Many aspects of metabolic syndrome are also seen in women with PCOS – including insulin resistance, obesity in some cases, and elevated cholesterol. Statistics indicate approximately 30% of women with PCOS have impaired glucose tolerance, while an additional 8% have diabetes.
  • Inflammation. Evidence suggests low-grade inflammation causes the ovaries to produce excess androgens (testosterone and its precursors).
  • Cardiovascular disease. Excess androgen hormones and being overweight can increase the risk for diseases of the heart and blood vessels.
  • Sleep apnea. In one study, women with PCOS were 30 times more likely to suffer from disordered breathing when sleeping than women without PCOS.
  • Fatty liver. Numerous clinical studies point to the increased prevalence of non-alcoholic fatty liver disease (NAFLD) in women with PCOS, independent of weight or other metabolic syndrome factors.

What can be done?

Although several medications can increase chances of conceiving or decrease the risk for some of the associated conditions, lifestyle choices can also help.

Follow a healthy, anti-inflammatory diet

Inflammation can inhibit fertility, and weight problems can contribute to inflammation. So a diet like the Mediterranean Diet that decreases exposure to inflammatory factors can be beneficial for reproductive health. In fact, one study showed that women on the Mediterranean Diet compared to women on a Western diet (higher in meat, fried foods, and simple carbs) were less likely to have fertility issues. A similar study found the Mediterranean Diet increased chances of becoming pregnant by 40% in women undergoing in vitro fertilization. 

Say no to HFCS

Avoid high-fructose corn syrup (HCFS) – found in sodas, sweetened fruit drinks, condiments, and many other processed foods. Studies show that HFCS is associated with unwanted weight gain, which can interfere with ovulation and fertility. In addition, HFCS is associated with increased risk for fatty liver.

Increase dietary vitamin D

In a study of women with PCOS, increased daily vitamin D intake resulted in a significant decrease in testosterone.* Other research has shown vitamin D helps maintain healthy inflammatory markers (measured as C-reactive protein) and decreases oxidative stress in women with PCOS.*

If you suspect you might have PCOS, then contact your health-care practitioner to help you sort things out. Talk to your health-care practitioner about Thorne’s at-home Fertility Test. In addition to testing for testosterone, DHEA, and sex-hormone binding globulin (all of which can be out of balance with PCOS), this tests for other reproductive hormones, thyroid hormones, and stress hormones.
