What is PCOS?
PCOS (polycystic ovary syndrome) is a hormonal condition that affects how the ovaries work. It's one of the most common causes of irregular periods and is closely linked to insulin resistance.
Symptoms
Common signs include irregular or absent periods, acne, excess facial or body hair (hirsutism), thinning scalp hair, and difficulty managing weight.
Causes
The exact cause isn't fully known, but insulin resistance, hormonal imbalance, and genetics all contribute.
Treatment
There's no cure, but symptoms are very manageable through diet, exercise, and — where appropriate — medication. Work with your clinician on a plan that fits you.
