NIH Websites Are Changing

Beginning in late July, NIH will start introducing a new website experience designed to make it easier to find health information, research, funding opportunities, and other resources. During the transition, you may notice changes to navigation, page layouts, and where some information is located.

What are the symptoms of PCOS?

Because the characteristic features of PCOS (also known as Polyendocrine Metabolic Ovary Syndrome [PMOS])—absence of ovulation, indicated by irregular menstrual periods or no periods at all; high androgen levels; and growths in one or both ovaries, often clumps of ovarian follicles that have stopped developing—are wide ranging, so, too, are the symptoms of the condition.

Often, women and health care providers may not suspect PCOS because the symptoms may seem unrelated. These can include:1,2

  • Menstrual irregularities:
    • No menstrual periods—called amenorrhea
    • Skipped periods—called oligomenorrhea
    • Very heavy periods
    • Bleeding but no ovulation—called anovulatory periods
  • Infertility
  • Increased hair growth on the face, chest, belly, or upper thighs—a condition called hirsutism
  • Severe, late-onset, or persistent acne that does not respond well to common treatments
  • Insulin sensitivity
  • Obesity, weight gain, or trouble losing weight, especially around the waist
  • Oily skin
  • Patches of thickened, dark, velvety skin—a condition called acanthosis nigricans

For many adolescents, these symptoms may also be part of puberty, especially early in the process. A health care provider may consider PCOS treatments for severe symptoms even without a diagnosis of PCOS.3

Because many women don't consider oily skin, increased hair growth, or acne to be symptoms of a serious health condition, they may not mention these things to their health care providers. As a result, many women aren't diagnosed with PCOS until they have trouble getting pregnant, or until they have menstrual irregularities.

Although PCOS is a leading cause of infertility, many women of reproductive age with PCOS can and do get pregnant. Pregnant women who have PCOS, however, are at higher risk for certain problems, such as miscarriage. Learn more about PCOS-related pregnancy problems.

Women with PCOS are also at higher risk for the following health issues:

  • Cardiovascular disease
  • Depression, anxiety, and other mental health issues
  • Endometrial hyperplasia , a condition in which the lining of the uterus becomes too thick, and endometrial cancer, also called uterine cancer
  • Insulin resistance, when the body doesn’t use insulin well
    • Too much glucose and insulin in the blood can contribute to metabolic syndrome and type 2 diabetes.
    • More than one-half of women with PCOS have insulin resistance.6
    • Patches of thickened, dark, velvety skin, called acanthosis nigricans, are associated with insulin resistance.
  • Metabolic syndrome, a group of risk factors for heart disease and type 2 diabetes
    • About 25% to 45% of women with PCOS have metabolic syndrome.7
  • Obesity
    • Obesity is a risk factor for many health problems, including diabetes, heart disease, high blood pressure, and sleep apnea.
    • About 4 out of 5 women with PCOS also have obesity.5
  • Obstructive sleep apnea, a disorder that causes pauses in breathing during sleep
    • Sleep apnea increases the risk of high blood pressure, heart attack, and diabetes.8
    • Women with PCOS are at much higher risk for obstructive sleep apnea than others, including those without PCOS and those with obesity.9
  • Type 2 diabetes
    • If not managed, diabetes can damage the kidneys and can lead to blindness, nerve damage, and foot problems.10 Type 2 diabetes also increases the risk for heart disease and high blood pressure.
    • More than one-half of women with PCOS will have either type 2 diabetes or prediabetes before their early 40s.11

Just because a woman is diagnosed with PCOS does not mean she will experience all these issues. However, she and her health care providers may want to monitor her health for signs of these issues as part of her regular care.
