What is PCOS?
Polycystic Ovary Syndrome (PCOS) is a complex hormonal disorder affecting 8-13% of reproductive-aged women worldwide. Despite its name, PCOS is not primarily about cysts on the ovaries, but rather a metabolic and reproductive condition characterized by hormonal imbalances.

The Science Behind PCOS
PCOS involves multiple body systems and is characterized by three main features, known as the Rotterdam Criteria. Understanding these helps explain why PCOS symptoms can vary so much between individuals.
Hormonal Imbalance
Elevated androgens (male hormones) leading to symptoms like acne and hair growth
Irregular Cycles
Infrequent or absent ovulation causing unpredictable periods
Polycystic Ovaries
Multiple small follicles visible on ultrasound examination
Common Symptoms
PCOS symptoms can vary significantly between individuals. Some women experience all symptoms, while others may have only a few. Here are the most common manifestations:
Irregular Menstrual Cycles
Cycles longer than 35 days, fewer than 8 periods per year, or completely absent periods
Weight Management Challenges
Difficulty losing weight, weight gain around the midsection, and insulin resistance
Skin and Hair Changes
Acne, excessive hair growth (hirsutism), male-pattern baldness, and dark skin patches
Diagnosis and Testing
PCOS diagnosis requires careful evaluation by a healthcare provider. There's no single test for PCOS, so doctors use a combination of symptoms, physical examination, and laboratory tests.
Diagnostic Process
1
Medical history and symptom assessment
2
Physical examination and measurements
3
Blood tests for hormone levels and glucose
4
Pelvic ultrasound to examine ovaries
Treatment and Management
While there's no cure for PCOS, effective management can significantly improve symptoms and reduce long-term health risks. Treatment is typically individualized based on symptoms and life goals.
Lifestyle Interventions
- Balanced, low-glycemic diet
- Regular physical activity
- Stress management techniques
- Adequate sleep (7-9 hours)
Medical Treatments
- Hormonal contraceptives
- Metformin for insulin resistance
- Anti-androgen medications
- Fertility treatments if needed
