What is polycystic ovary syndrome (PCOS), and what symptoms can it cause?
Short answer
PCOS is a hormonal condition that can affect periods, skin, hair, and fertility. Common signs include irregular periods, acne, unwanted facial or body hair, and thinning scalp hair. Some people also have weight gain or insulin resistance. You can have PCOS without having ovarian cysts.
Polycystic ovary syndrome, or PCOS, affects how the ovaries work and how the body handles certain hormones. Many people with PCOS have higher levels of androgens. These hormones are present in everyone, but higher levels can contribute to acne, unwanted hair growth, and scalp hair thinning.
PCOS can also disrupt ovulation, which is the release of an egg. Periods may be far apart, unpredictable, or absent. Some people have heavy bleeding when a period does occur. Weight gain and insulin resistance are also common, but PCOS affects people of all body sizes.
Despite its name, PCOS does not require ovarian cysts. What an ultrasound may show are many small follicles, which are sacs where eggs develop. An ultrasound finding alone does not prove that someone has PCOS.
Symptoms differ from person to person and can change over time. A licensed physician in your state can review your symptoms and health history to decide what testing and care are appropriate. Treatment focuses on your health needs and goals.
