Last updated: April 1, 2026

Quick Answer: PCOS (Polycystic Ovary Syndrome) is a hormonal disorder affecting women of reproductive age, characterized by irregular periods, excess androgen levels, and ovarian cysts. It is one of the most common endocrine disorders in women.

Key Facts

Understanding PCOS

Polycystic Ovary Syndrome (PCOS) is an endocrine disorder that affects women during their reproductive years, typically diagnosed between the ages of 20 and 40. The condition is characterized by the development of multiple small cysts on the ovaries, though not all women with PCOS have cysts. PCOS involves a complex interplay of hormonal imbalances, insulin resistance, and inflammatory responses.

Symptoms

Common symptoms of PCOS include irregular or absent menstrual periods, heavy or prolonged bleeding, excessive hair growth (hirsutism), acne, male-pattern baldness, and darkening of the skin in body folds. Women may also experience weight gain, difficulty losing weight, fertility issues, and mood disorders. Symptoms vary widely among individuals, making diagnosis challenging.

Causes and Risk Factors

The exact cause of PCOS remains unknown, but research suggests insulin resistance, inflammation, and genetic factors play significant roles. Women with insulin resistance often have higher levels of insulin in their blood, which may stimulate the ovaries to produce excess androgens, disrupting normal ovulation. Family history of PCOS or type 2 diabetes increases the risk of developing the condition.

Diagnosis and Management

PCOS is typically diagnosed through a combination of clinical symptoms, hormonal tests, and ultrasound imaging showing ovarian cysts. There is no single test for PCOS, so diagnosis often involves ruling out other conditions. Management includes lifestyle modifications such as diet and exercise, medications to regulate hormones and insulin levels, and fertility treatments for women seeking pregnancy.

Long-term Health Implications

Women with PCOS face increased risks of type 2 diabetes, cardiovascular disease, and metabolic syndrome. Regular monitoring and management are essential to prevent complications. Early intervention and lifestyle changes can significantly improve outcomes and quality of life for women with PCOS.
