Polycystic Ovarian Syndrome (PCOS) is the most common hormonal disorder among women of reproductive age, affecting an estimated 7–15 percent of women worldwide.
PCOS can be a mystery to doctors and patients alike. The classic signs of this disorder are obesity, acne, irregular periods, and facial hair—yet some women never display these symptoms. As a result, many women may go years without realizing they have PCOS because they don’t have the textbook symptoms.
