What is Polycystic Ovary Syndrome (PCOS)? A Patient's Guide
Learn about Polycystic Ovary Syndrome (PCOS), its symptoms, causes, and when to consult a doctor.
Polycystic Ovary Syndrome (PCOS) is a common hormonal disorder affecting women of reproductive age. It is characterized by irregular menstrual periods, excess male hormone levels, and polycystic ovaries, which are ovaries containing numerous small cysts. Understanding PCOS is important as it can impact fertility, metabolic health, and overall well-being.
What is PCOS?
Polycystic Ovary Syndrome (PCOS) is a condition that affects a woman's hormone levels, leading to various symptoms and health issues. Women with PCOS may have infrequent or prolonged menstrual periods or excess androgen, which are male hormone levels. The ovaries may develop numerous small collections of fluid (follicles) and fail to regularly release eggs.
Why does PCOS matter?
PCOS is significant because it can lead to a variety of health problems, including infertility, obesity, type 2 diabetes, and cardiovascular disease. Women with PCOS are also at a higher risk of developing endometrial cancer (cancer of the uterine lining). Early diagnosis and management can help mitigate these risks and improve quality of life.
Causes and risk factors
The exact cause of PCOS is unknown, but several factors may play a role:
- Genetic factors: PCOS tends to run in families, suggesting a genetic component.
- Insulin resistance: Many women with PCOS have insulin resistance, where the body's cells do not respond effectively to insulin, leading to increased insulin production. High insulin levels can increase androgen production, worsening PCOS symptoms.
- Low-grade inflammation: Research has shown that women with PCOS often have low-grade inflammation, which can stimulate polycystic ovaries to produce androgens.
Common symptoms of PCOS
Symptoms of PCOS can vary but often include:
- Irregular menstrual cycles: This can mean fewer than nine periods a year, prolonged periods, or heavy bleeding.
- Excess androgen: High levels of male hormones can result in physical signs such as excess facial and body hair (hirsutism), severe acne, and male-pattern baldness.
- Polycystic ovaries: Enlarged ovaries containing numerous small cysts.
- Weight gain: Many women with PCOS experience weight gain or find it difficult to lose weight.
