What Is Polycystic Ovary Syndrome?

Polycystic ovary syndrome (PCOS) occurs when a woman's hormones are out of balance, causing problems with the reproductive process.

PCOS typically starts at puberty and causes irregular periods and later, difficulty getting pregnant. The condition may affect the way you look and may increase the risk of serious health problems later on – which may include type 2 diabetes, heart disease, and endometrial (uterine) cancer.

Most women with PCOS grow many small cysts on their ovaries. The cysts are not harmful but may lead to the hormone imbalances.

Early diagnosis and treatment can help control the symptoms and prevent long-term health problems.

What Are the Symptoms of PCOS?


  • Irregular menstrual periods, or lack of menstrual periods
  • Reduced or lack of ovulation, interfering with infertility
  • Weight gain in the upper body and abdomen
  • Persistent acne, oily skin and oily hair in adulthood
  • Abnormal hair growth (facial, arms, chest, and abdomen)
  • Uncontrolled blood sugar and type 2 diabetes

What Causes PCOS?

Researchers are investigating the cause, but have been unable to determine what triggers PCOS. Family history and genetics are considered to play a role.
