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.

- 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.
