Polycystic Ovary Syndrome : 5 Common Signs and When to See a Doctor

Polycystic Ovary Syndrome : 5 Common Signs and When to See a Doctor

Polycystic Ovary Syndrome (PCOS) is much more than just a hormonal imbalance; it is a complex metabolic condition that affects millions of women worldwide.

Despite being a leading cause of infertility, it is estimated that up to 50% of women with PCOS remain undiagnosed.

Understanding the signs and long-term health implications is vital for early intervention and preventing complications like Type 2 diabetes.

1. What is PCOS?

PCOS is an endocrine (hormonal) disorder that affects how a woman’s ovaries function. It is defined by a “syndrome” of symptoms, meaning not every woman will experience it the same way.

To receive a clinical diagnosis, doctors typically use the Rotterdam Criteria, requiring at least two of the following:

• • Irregular Periods: Infrequent or absent ovulation.

  • High Androgen Levels: Physical or biochemical signs of “male” hormones.

  • Polycystic Ovaries: An ultrasound showing 12 or more small follicles (underdeveloped egg sacs) on the ovaries.

2. 5 Common Signs of PCOS

If you notice these symptoms, it may indicate that your hormone levels are out of balance:

1. Menstrual Irregularities

This is the most frequent sign. You may have fewer than nine periods a year, cycles that last longer than 35 days, or periods that disappear entirely (amenorrhea). This happens because the hormonal “signal” to release an egg is disrupted.

2. Excessive Hair Growth (Hirsutism)

Excess androgens can cause dark, thick hair growth in areas usually associated with men, such as the face, chest, stomach, or back. Conversely, some women experience thinning hair on the head (male-pattern baldness).

3. Persistent Acne and Oily Skin

While common in puberty, PCOS-related acne often persists into adulthood and is typically found along the jawline. It is often resistant to standard over-the-counter skin treatments because the root cause is internal and hormonal.

4. Difficulty Managing Weight

Approximately 40% to 80% of women with PCOS are classified as having obesity. Because PCOS is closely linked to insulin resistance, the body struggles to convert sugar into energy, leading to weight gain—particularly around the abdomen—and making weight loss significantly harder.

5. Skin Discolouration (Acanthosis Nigricans)

Insulin resistance can cause patches of thickened, velvety, darkened skin. These are most commonly found in the folds of the neck, armpits, or groin.

3. When to See a Doctor

You should schedule an appointment with your GP or a gynecologist if:

• You have missed periods and you are not pregnant.

• You are struggling to conceive after 12 months of trying (or 6 months if over age 35).

• You notice sudden, excessive hair growth on your face or body.

• You have symptoms of diabetes, such as extreme thirst or frequent urination.

Why early action matters: Women with PCOS are at a much higher risk for long-term health issues. Statistically, over 50% of women with PCOS will develop Type 2 diabetes by age 40.

4. Causes and Risk Factors

While the exact cause is an enigma, research points to a combination of genetics and lifestyle.

• Insulin Resistance: Up to 70% of women with PCOS have insulin resistance. This causes the body to produce more insulin, which in turn signals the ovaries to produce more testosterone.

• Ethnicity: Statistics show that prevalence and severity vary by background. For example, women of South Asian descent often present with symptoms at a lower BMI and have a higher risk of developing insulin resistance compared to other groups.

• Genetics: If your mother or sister has PCOS, your risk is significantly higher.

5. Treatment and Management

There is no “cure” for PCOS, but it is highly manageable. Treatment is tailored to your specific goals, such as regulating your cycle or getting pregnant.

• Lifestyle Changes: This is the “gold standard” of treatment. Losing just 5–10% of body weight has been shown to restore normal ovulation and significantly improve energy levels.

• The Contraceptive Pill: Often used to regulate periods and lower androgen levels, which helps clear acne and reduce hair growth.

• Metformin: Though primarily a diabetes medication, it is frequently prescribed for PCOS to improve insulin sensitivity.

• Fertility Support: Medications like Letrozole or Clomifene can help trigger ovulation for those trying to start a family.
