PCOS Explained: Symptoms, Causes, and What Actually Helps

Polycystic Ovary Syndrome (PCOS) is a common endocrine and metabolic disorder affecting an estimated 8-13% of women of reproductive age globally. Despite its name, the presence of ovarian cysts is not required for diagnosis - the condition instead relies on a broader set of hormonal and metabolic criteria known as the Rotterdam Criteria.

The underlying mechanisms of PCOS frequently involve insulin resistance combined with elevated ovarian androgen production. Elevated circulating insulin can stimulate the ovaries to produce excess testosterone, which disrupts normal ovulation cycles and leads to common physical symptoms like adult acne, hirsutism (excess hair growth), and male-pattern hair thinning.

Diagnosis typically follows the Rotterdam Criteria, requiring at least two of three markers: irregular or absent ovulation cycles, clinical or biochemical signs of hyperandrogenism, and polycystic ovaries on ultrasound. Because these criteria vary in expression, PCOS presents very differently between individuals - making personalized treatment essential.

Treatment is individualized based on the patient's primary goals. For hormonal cycle management, combined oral contraceptives remain the first-line pharmacological option for those not seeking fertility. For insulin resistance and metabolic symptoms, metformin has strong evidence. For fertility support, ovulation induction with letrozole is now preferred over clomiphene citrate based on superior live birth rates in recent trials.

Lifestyle interventions are foundational: even a 5-10% reduction in body weight in women with PCOS who are overweight significantly improves insulin sensitivity, restores menstrual regularity, and reduces androgen levels. A low-glycemic, anti-inflammatory dietary pattern and consistent aerobic exercise (at least 150 minutes per week) are among the most powerful tools available - and without the side-effect profile of medications.
