September 1 is World PCOS Day.
PCOS, or polycystic o***y syndrome, is a common hormonal condition that affects how the ovaries function. It can involve higher-than-normal levels of androgens, irregular or absent ovulation, and sometimes multiple small follicles seen on the ovaries.
PCOS can cause symptoms such as irregular periods, acne, excess facial or body hair, hair thinning, weight changes, and difficulty becoming pregnant. It can also be linked with insulin resistance and a higher risk of conditions like type 2 diabetes.
PCOS affects an estimated 10–13% of women of reproductive age, and many remain undiagnosed.
