Polycystic ovary syndrome (PCOS) is a common hormonal disorder that affects women. An estimated 5-10% of women of reproductive age have PCOS. The name refers to the enlarged ovaries that contain small fluid-filled sacs called follicles. What causes PCOS? The exact cause is unknown, but it likely involves a combination of genetic and environmental factors that affect hormones and cause problems with ovulation and metabolism. Key factors believed to play a role include:
- Insulin resistance - Many women with PCOS are resistant to the effects of insulin in the body. Higher insulin levels can increase androgen hormone production, which interferes with ovulation.
- Inflammation - Some research shows that women with PCOS have chronic low-grade inflammation, which stimulates polycystic ovaries to produce androgens.
- Heredity - PCOS seems to run in families, so genes likely play a role. Daughters of women with PCOS have a 50% chance of developing it.
- Irregular periods - This is the most common symptom. Periods may be very heavy, very light, or absent.
- Infertility - Many women with PCOS have difficulty getting pregnant due to lack of ovulation.
- Weight gain - Up to 80% of women with PCOS are overweight or obese.
- Excess hair growth - More than 70% grow coarse or thick hair on the face, chest, belly, or back.
- Acne - 30% have severe acne, especially along the jawline and neck.
- Hair loss - Some women experience male-pattern baldness due to high androgen levels.
- Skin tags - Small flaps of skin in body fold areas are common.
- Review your medical history and ask about your symptoms
- Conduct a physical exam to check for signs like excess hair growth
- Run blood tests to check hormone and glucose levels
- Perform an ultrasound to examine your ovaries

- Polycystic ovaries seen on an ultrasound
- Lose weight - Just 5-10% in body weight can help regulate menstrual cycles and improve PCOS symptoms.
- Healthy diet - Choose high fiber carbs, lean protein, healthy fats. Limit processed foods.
- Exercise - Aim for 30-60 minutes per day to help manage weight and insulin levels.
- Birth control pills - Oral contraceptives can help regulate menstrual cycles and reduce androgen levels.
- Fertility treatments - Medications can stimulate ovulation for women trying to conceive.
