Polycystic ovarian syndrome, more commonly known as PCOS, is the most common cause of infertility among women in the U.S. But beyond posing problems to those hoping to get pregnant, PCOS also comes along with a number of unpleasant symptoms like acne or extra hair. Here’s what you need to know about PCOS, what symptoms to look for and what you can do if you think you might be affected.

What is PCOS?

While PCOS is extremely common, the cause of the syndrome remains unknown. It’s likely that a host of factors are collaborating to upend the normal balance of hormones in a woman’s body, which leads to changes in her period and unpleasant symptoms related to hormonal imbalance.

PCOS is a syndrome or list of symptoms that often come together, rather than a single disease. In fact, many doctors think that the symptoms of PCOS are actually caused by several diseases that happen to occur together. For example, diabetes and obesity appear to contribute to the symptoms of PCOS by changing the way the body handles hormones and the way those hormones act in the brain and on the reproductive organs. But there’s also some indication that genetics may play a role in making someone more or less likely to be sensitive to these kinds of hormonal shifts.

Who’s at risk for PCOS?

  • Some of the following factors appear to be related to PCOS and may increase your risk for the syndrome:
  • Having a family member who has or had PCOS
  • Having irregular periods
  • Having diabetes
  • Being overweight or obese

What are the symptoms of PCOS?

The following symptoms are commonly seen in women who have PCOS:

  • Male patterns of hair, including facial hair, chest hair, belly hair, back hair and increased arm or leg hair.
  • Acne, especially acne that doesn’t seem to get better with normal skin treatments for acne.
  • Balding is less common, but can be seen either in a male pattern on the front of the head or closer to the center of the head.
  • Irregular periods that don’t follow a regular schedule. Some women with PCOS find their periods stop completely.
  • Ovaries that appear to have large cysts on them when imaged with an ultrasound machine.

It’s important to remember that not all women will have all of these symptoms. PCOS is often a variable syndrome and different women can have a different mix of associated problems.
