Polycystic Ovary Syndrome (PCOS)

Condition Basics

What is polycystic ovary syndrome (PCOS)?

Polycystic ovary syndrome (PCOS) is a hormone imbalance that can affect ovulation. It can cause problems with your periods and make it hard to get pregnant. PCOS may also cause other symptoms, such as weight gain, acne, or hair growth on the face or body. If it isn't treated, over time it can lead to serious health problems, such as diabetes and heart disease.

Most of those who have PCOS grow many small cysts on their ovaries. That's why it's called polycystic ovary syndrome.

In polycystic ovary syndrome, cysts may form on the ovaries. A cyst is a sac-shaped structure in the body. Cysts usually are filled with fluid.

What causes PCOS?

PCOS is caused by hormones that are out of balance. What causes the imbalance isn't fully understood. But genetics may be a factor. PCOS seems to run in families. Your chance of having it is higher if others in your family have PCOS or have diabetes.

What are the symptoms?

Symptoms of PCOS usually start gradually. They may include acne and oily skin, weight gain and trouble losing weight, extra hair on the face and body, thinning hair on the scalp, irregular periods, problems getting pregnant, and depression. PCOS may be more noticeable after a weight gain.

How is it diagnosed?

To diagnose PCOS, the doctor will ask questions about your symptoms and menstrual cycles. The doctor will also do a physical exam. You'll have some lab tests to check your blood sugar, insulin, and other hormone levels. You may also have an ultrasound to look for cysts on your ovaries.

How is PCOS treated?

Regular exercise, healthy foods, and weight control are the key treatments for PCOS. Your doctor may prescribe birth control pills to reduce symptoms and help regulate your periods, or fertility medicines for problems getting pregnant. Treatment can reduce symptoms and help prevent long-term health problems.
