Polycystic ovary syndrome (PCOS) is a condition that occurs when an imbalance of hormone levels in a woman’s body causes cysts (say: “sists”) to form in the ovaries. The cysts are like tiny, fluid-filled balloons.

PCOS can cause changes in a woman’s menstrual cycles, fertility, hormone levels, heart and blood vessels, and appearance.

Women can develop PCOS during their teenage or childbearing years.


What are the symptoms of PCOS?

Usually, women who have PCOS have irregular, infrequent or no menstrual periods. They may also have trouble getting pregnant. Some women who have PCOS do not experience any symptoms.

Other signs and symptoms of PCOS may include:

  • Acne
  • Overweight and obesity
  • Excessive hair growth on the face, nipple area, chest, lower abdomen and thighs
  • Thinning hair or bald spots
  • Dark patches of skin
  • Anxiety or depression
  • Pelvic pain

Women who have PCOS are also more likely to have type 2 diabetes, high blood pressure and high cholesterol and triglycerides. Together with obesity, these conditions are known as the “metabolic syndrome.”

Causes & Risk Factors

What causes PCOS?

Doctors do not know exactly what causes PCOS. If you have PCOS, you have a hormone imbalance. Your ovaries make too much of one type of hormone (called androgens). You may also have too much insulin, which regulates your blood sugar levels. These hormone problems cause the symptoms of PCOS.

What are the risk factors for PCOS?

You are more likely to have PCOS if your mother or sister has PCOS.

Diagnosis & Tests

How can my doctor tell that I have PCOS?

Your doctor will ask you about your symptoms and will look for the signs of PCOS. He or she will give you a full physical examination, which will most likely include a pelvic exam. Blood tests that measure your hormone levels can also help. An ultrasound exam can show if you have cysts on your ovaries.


How is PCOS treated?

Treatment for PCOS focuses on managing the symptoms. You might need to lose weight. Eating healthy and getting plenty of exercise can help manage PCOS.

Medicine can help regulate your menstrual cycle and reduce abnormal hair growth and acne. Birth control pills (for women not trying to have a baby) and metformin are 2 prescription medicines that are often helpful. If you have diabetes or high blood pressure, those conditions also need treatment. If you want to have a baby, there are medicines that may help you get pregnant.


Does PCOS cause long-term problems?

If you have PCOS, you are more likely to develop high blood pressure, high cholesterol or type 2 diabetes. This means you have a greater risk for strokes and heart attacks.

Problems with menstrual periods may also cause women who have PCOS to be infertile (unable to get pregnant). They may also have a higher risk for cancer of the uterus or breast.

Women who have PCOS are also more likely to have anxiety or depression. If you are feeling anxious or depressed, talk to your doctor. Treatment is available.
