What Is PCOS? Causes, Symptoms, Diagnosis, and Treatment
Polycystic Ovary Syndrome (PCOS) is a common hormonal disorder that affects millions of women of reproductive age. Despite its prevalence, many women remain undiagnosed or misdiagnosed. Understanding PCOS—its causes, symptoms, diagnosis, and treatment options—is key to managing the condition and improving overall health.
What Is PCOS?
PCOS (Polycystic Ovary Syndrome) is a hormonal imbalance that affects how the ovaries work. It is characterized by irregular menstrual cycles, elevated levels of male hormones (androgens), and the presence of multiple small cysts on the ovaries.
Women with PCOS may experience a variety of symptoms, ranging from irregular periods to fertility issues and weight gain. The exact cause of PCOS is unknown, but genetics, insulin resistance, and inflammation are believed to play major roles.
Common Symptoms of PCOS
Symptoms of PCOS can vary widely from person to person, but the most common include:
-
Irregular or missed periods
-
Excess hair growth (hirsutism) on the face, chest, or back
-
Acne or oily skin
-
Weight gain or difficulty losing weight
-
Thinning hair or hair loss on the scalp
-
Darkening of the skin, especially around the neck, groin, or under breasts
-
Polycystic ovaries (visible on ultrasound)
-
Difficulty getting pregnant due to irregular ovulation
What Causes PCOS?
While the exact cause of PCOS remains unclear, several factors contribute to its development:
-
Insulin resistance: High insulin levels can increase androgen production, leading to symptoms like acne and hirsutism.
-
Hormonal imbalance: Elevated levels of androgens (male hormones) disrupt ovulation.
-
Genetics: PCOS tends to run in families.
-
Chronic low-grade inflammation: This can stimulate polycystic ovaries to produce more androgens.
How Is PCOS Diagnosed?
There is no single test for PCOS. Diagnosis typically involves:
-
Medical history review
-
Physical examination
-
Blood tests to check hormone levels, insulin, cholesterol, and glucose
-
Pelvic ultrasound to examine ovaries and uterus
Doctors often use the Rotterdam criteria, which require two of the following three signs:
-
Irregular or absent ovulation
-
Excess androgen levels (symptoms or blood test)
-
Polycystic ovaries on ultrasound
Treatment Options for PCOS
PCOS has no cure, but symptoms can be managed effectively through lifestyle changes, medications, and, in some cases, fertility treatments.
1. Lifestyle Modifications
-
Healthy diet: Focus on whole foods, low sugar, and anti-inflammatory ingredients.
-
Regular exercise: Helps with weight management and improves insulin sensitivity.
-
Weight loss: Even a 5–10% reduction in body weight can restore ovulation.
2. Medications
-
Birth control pills: Regulate periods and reduce androgen levels.
-
Metformin: Improves insulin sensitivity and may help with weight loss and ovulation.
-
Anti-androgens: Reduce hair growth and acne.
-
Clomiphene or Letrozole: Stimulate ovulation in women trying to conceive.
3. Fertility Treatments
-
Ovulation induction medications
-
Intrauterine insemination (IUI)
-
In vitro fertilization (IVF) for more complex fertility issues
PCOS and Long-Term Health Risks
Untreated PCOS can lead to several complications, including:
-
Infertility
-
Type 2 diabetes
-
High blood pressure
-
Heart disease
-
Sleep apnea
-
Endometrial cancer
-
Mental health issues such as anxiety and depression
Regular check-ups and early management can significantly reduce these risks.
Can You Prevent PCOS?
While PCOS itself may not be preventable, managing lifestyle factors like diet, weight, and physical activity can help reduce the severity of symptoms and lower the risk of long-term complications.
PCOS (Polycystic Ovary Syndrome) is a complex but manageable condition. Early diagnosis, lifestyle changes, and appropriate treatment can greatly improve quality of life and reproductive health. If you experience symptoms of PCOS, speak with a healthcare provider to explore your treatment options and create a personalized management plan.
