Polycystic Ovary Syndrome (PCOS) is one of the most common hormonal disorders affecting people with ovaries during their reproductive years. Despite how common it is, PCOS is frequently misunderstood or diagnosed late, which can delay effective treatment.
What Is PCOS?
PCOS is a hormonal imbalance that affects ovarian function. It’s characterized by a combination of symptoms rather than a single test, which is part of why it can be tricky to diagnose.
Common Symptoms
- Irregular or absent menstrual periods
- Excess androgen levels, leading to acne or excess facial/body hair (hirsutism)
- Polycystic ovaries visible on ultrasound (multiple small follicles)
- Weight gain or difficulty losing weight
- Thinning hair on the scalp
- Difficulty getting pregnant due to irregular ovulation
What Causes PCOS?
The exact cause isn’t fully understood, but several factors are believed to play a role:
- Insulin resistance: Many people with PCOS have insulin resistance, which can raise androgen levels.
- Genetics: PCOS tends to run in families.
- Low-grade inflammation: This can stimulate polycystic ovaries to produce androgens.
Diagnosis
Diagnosis typically involves a combination of a physical exam, blood tests to check hormone levels, and a pelvic ultrasound. Doctors often use the Rotterdam criteria, which requires at least two of three features: irregular ovulation, signs of excess androgens, and polycystic ovaries on imaging.
Treatment Options
There’s no single cure for PCOS, but symptoms can be effectively managed:
- Lifestyle changes: A balanced diet and regular exercise can improve insulin sensitivity and help regulate cycles.
- Medications: Hormonal birth control can regulate periods and reduce androgen-related symptoms; metformin may help with insulin resistance.
- Fertility treatment: For those trying to conceive, medications like letrozole or clomiphene can help induce ovulation.
- Targeted therapies: Treatments for specific symptoms, such as anti-androgen medications for excess hair growth or acne.
When to See a Doctor
If you’re experiencing irregular periods, unexplained weight changes, excess hair growth, or difficulty conceiving, it’s worth talking to a healthcare provider. Early diagnosis and management can reduce long-term risks associated with PCOS, including type 2 diabetes and cardiovascular disease.
