Polycystic ovary syndrome (PCOS) is one of the most common hormonal disorders affecting women of reproductive age, yet it remains widely misunderstood. It is estimated that 1 in 10 women have PCOS, and many go undiagnosed for years. Understanding the condition is the first step toward managing it effectively.
What Is PCOS?
PCOS is a hormonal imbalance that affects how the ovaries function. Despite its name, not all women with PCOS have ovarian cysts. The condition is characterized by a combination of symptoms related to excess androgen (male hormone) production, irregular ovulation, and metabolic dysfunction. The exact cause is not fully understood, but genetics, insulin resistance, and inflammation all play a role.
Common Symptoms
PCOS presents differently in every woman, which is part of why it can be difficult to diagnose. Common symptoms include:
- Irregular periods: Cycles that are longer than 35 days, unpredictable, or absent altogether.
- Excess hair growth (hirsutism): Coarse hair on the face, chest, back, or abdomen due to elevated androgens.
- Acne and oily skin: Hormonal acne that often persists well beyond adolescence, particularly along the jawline and chin.
- Thinning hair: Hair loss or thinning on the scalp in a pattern similar to male-pattern baldness.
- Weight gain: Difficulty losing weight, especially around the midsection, often linked to insulin resistance.
- Difficulty conceiving: Irregular or absent ovulation is a leading cause of infertility in women with PCOS.
- Skin darkening: Dark patches of skin (acanthosis nigricans) in body folds such as the neck, groin, and underarms.
How Is PCOS Diagnosed?
There is no single test for PCOS. Diagnosis is typically based on the Rotterdam criteria, which require at least two of the following three findings:
- Irregular or absent ovulation
- Clinical or biochemical signs of excess androgens
- Polycystic-appearing ovaries on ultrasound
Your provider will also order blood tests to measure hormone levels (including testosterone, DHEA-S, and LH/FSH ratio), check blood sugar and insulin levels, and rule out other conditions like thyroid disorders or adrenal hyperplasia that can mimic PCOS symptoms.
Treatment Options
While there is no cure for PCOS, a combination of medical treatment and lifestyle changes can effectively manage symptoms and reduce long-term health risks.
Lifestyle Changes
Lifestyle modifications are the foundation of PCOS management. Even a modest 5-10% reduction in body weight can significantly improve symptoms by lowering insulin levels and restoring more regular ovulation. Focus on:
- A balanced diet rich in whole grains, lean proteins, fruits, and vegetables while limiting refined carbohydrates and added sugars.
- Regular physical activity, aiming for at least 150 minutes of moderate exercise per week.
- Adequate sleep and stress management, both of which affect hormonal balance.
Medical Treatments
- Hormonal birth control: Pills, patches, or hormonal IUDs help regulate periods, reduce androgens, and protect the uterine lining.
- Metformin: Commonly used to improve insulin sensitivity, which can help restore ovulation and support weight management.
- Anti-androgen medications: Spironolactone can reduce excess hair growth and acne.
- Fertility treatments: For women trying to conceive, medications like letrozole or clomiphene citrate can stimulate ovulation.
