What is Polycystic Ovary Syndrome?
Polycystic Ovary Syndrome, also known as PCOS, is a reproductive condition with an unknown etiology. PCOS affects 4–20% of women of reproductive age. PCOS is one of the most common causes of female infertility, affecting 6% to 12% (as many as 5 million) of US women of reproductive age. It is diagnosed by the existence of two of the three following criteria: hyperandrogenism, polycystic ovaries, and ovulatory dysfunction.
Hyperandrogenism is a condition where the body produces an excessive amount of androgens (male sex hormones). Due to the production of excess androgen, the ovaries produce high amounts of testosterone in the body The influx of androgens can be due to many reasons, there are other hormones such as luteinizing hormone (LH) and adrenocorticotrophic that influence the production of androgens. These hormones are released from the pituitary gland and if they are not working properly they can cause an increase of androgens in the body. For women with high levels of androgens, the body may not ovulate due to hormonal imbalance. High levels of androgens may also cause excessive hair growth on the face/body and hair loss on the head.
During ovulation, mature eggs are released from the ovaries and can be fertilized. Sometimes, when ovulation doesn’t occur, the ovaries can develop cysts (fluid-filled sacs), from the underdeveloped eggs that did not mature from ovulation. These are also known as polycystic ovaries, which are mostly harmless and cause no pain. People diagnosed with PCOS might not even develop cysts. The last criterion we will discuss is ovulatory dysfunction which is when a woman has an irregular, infrequent, or complete absence of a period. Individuals with PCOS are at an increased risk for type 2 diabetes, increased blood pressure and cholesterol, depression, anxiety, and endometrial cancer.⁸
Signs and Symptoms
· Irregular menstrual periods
· Infertility
· Acne
· Obesity
· Insulin resistance
· Cysts
· Excessive hair growth on the body and face – Hirsutism
· Loss of hair on the head
Insulin resistance
People with PCOS can have insulin resistance, where the body’s cells don’t respond properly to insulin. Since the cells in the body are unable to respond to insulin, excess glucose is left in the bloodstream which causes spikes in our blood sugar. These sugar spikes can cause an individual to be tired throughout the day, have frequent urination, and increased thirst. Over time, insulin resistance can lead to pre-diabetes and then type 2 diabetes.
Diet and PCOS
We want to manage blood glucose levels and inflammation in the body to balance our hormones, which food can help with!! When creating meals, we want them to be balanced, full of protein, fiber, healthy fats, and whole grains (YES you are allowed to eat carbs with PCOS!). Creating balanced meals will help stabilize blood sugar throughout the day and help reduce inflammation in the body.
Foods to consider:
Consume high-fiber foods: Fiber helps stabilize blood sugar levels and will keep you full through the day. It also helps with your gut health and bowel movements. Sources include
· Oats
· Beans and lentils
· Whole grains
· Fruits and vegetables, especially cruciferous vegetables like broccoli and Brussel sprouts
Consume Anti-inflammatory foods: Inflammation directly stimulates excess ovarian androgen production. Sources include
· Berries
· Fatty fish- salmon, sardines, and sardines
· Avocado
· Green tea
· Turmeric
*See Dr. Wiel’s Anti-inflammatory pyramid for more.
Supplements/Herbs to consider
* Disclaimer: Please talk to your physician before adding any new supplements/herbs to your regime.
Inositol
Inositol is a sugar made in the body that acts as a B vitamin. It was shown that it may improve the body’s sensitivity to insulin by playing a role in insulin signaling. Studies have shown that inositol can help manage insulin resistance in women who have PCOS.
Berberine
Berberine is an herbal medicine from various plants, and studies have shown that it can manage insulin resistance, diabetes, and inflammation in the body. Studies have reported that berberine can increase insulin sensitivity, promote insulin production, regulate metabolism, and increase glycolysis, or the breakdown of glucose.
Spearmint tea
Studies suggested Spearmint tea can reduce androgen levels in women and helped reduce excessive hair growth. Studies reported that drinking two cups of spearmint tea a day may reduce facial hair because it may reduce testosterone. Testosterone is linked to the growth of facial hair. More research needs to be done on the effectiveness of Spearmint tea and decreasing facial hair.
Vitamin D
Vitamin D aids in ovarian follicular development, and the prevalence of vitamin D deficiency in women with PCOS is about 67-85 percent. Low levels of Vitamin D may exacerbate the symptoms of PCOS, including insulin resistance, ovulatory, menstrual irregularities, infertility, hyperandrogenism, and obesity, and elevate the risk of cardiovascular diseases.
Lifestyle Practices
Lifestyle practices including stress management, sleep, and exercise are just as important as fueling our bodies. Stress can cause the overproduction of androgen hormones and overall just not make us feel our best. Remember to find a stress management tool that works for you such as deep breathing, journaling, yoga, and taking a walk. Exercise can come in many forms, but women with PCOS may want to participate in low-intensity workouts and strength training. High-Intensity cardio workouts may cause our stress hormone cortisol to increase which may increase insulin, (which we do not want). Sleep is important for our well-being and helps us have the energy to get through our day. It is important to get adequate sleep, or it can cause the body to create stress and make us feel fatigued
In summary, Polycystic Ovary Syndrome (PCOS) is a reproductive condition with an unknown etiology. While there is no cure, nutrition and lifestyle practices can help manage symptoms and help you become a healthier you!
