PCOS: Symptoms, Causes & Treatment Options

By Dr. Priya Singhmor — MBBS, MS (OBGY), Laparoscopic Surgeon

Understanding Polycystic Ovary Syndrome (PCOS)

Polycystic Ovary Syndrome (PCOS) is one of the most common hormonal disorders affecting women of reproductive age, impacting approximately 8-13% of women worldwide. Despite its prevalence, many women remain undiagnosed, making awareness and education crucial for early detection and effective management.

As an experienced gynecologist, I frequently encounter patients struggling with PCOS-related symptoms. This comprehensive guide will help you understand this condition, recognize its signs, and explore the various treatment options available today.

What is PCOS?

PCOS is a complex hormonal disorder characterized by an imbalance in reproductive hormones. Women with PCOS typically have higher levels of androgens (male hormones), which can interfere with the development and release of eggs during ovulation.

The name "polycystic" refers to the appearance of the ovaries in some women with this condition—they may contain numerous small follicles (fluid-filled sacs) that fail to regularly release eggs.

Key Characteristics of PCOS

• Hormonal imbalance with elevated androgen levels
• Irregular or absent ovulation
• Multiple small follicles on the ovaries (visible on ultrasound)
• Metabolic disturbances including insulin resistance

Common Symptoms of PCOS

PCOS presents differently in each woman, but there are several hallmark symptoms to watch for:

Menstrual Irregularities

• Irregular periods (cycles longer than 35 days)
• Absent periods (amenorrhea)
• Heavy or prolonged bleeding during periods
• Unpredictable menstrual cycles

Physical Signs

• Hirsutism (excess hair growth on face, chest, back, or abdomen)
• Acne that persists beyond teenage years
• Hair thinning or male-pattern baldness
• Darkening of skin in body creases (acanthosis nigricans)
• Skin tags around the neck or armpits

Reproductive Concerns

• Difficulty getting pregnant (infertility)
• Recurrent miscarriages
• Irregular ovulation

Metabolic Symptoms

• Unexplained weight gain, particularly around the abdomen
• Difficulty losing weight
• Fatigue and low energy levels

Causes and Risk Factors

The exact cause of PCOS remains unclear, but several factors are believed to contribute:

1. Insulin Resistance

Up to 70% of women with PCOS have insulin resistance, where cells don't respond properly to insulin. This leads to:

• Higher insulin levels in the blood
• Increased androgen production
• Disrupted ovulation
• Weight gain and difficulty losing weight

2. Hormonal Imbalances

• Elevated androgens interfere with ovulation
• Elevated LH (luteinizing hormone) disrupts the menstrual cycle
• Low levels of SHBG (sex hormone-binding globulin)

3. Genetic Factors

PCOS tends to run in families. If your mother or sister has PCOS, your risk is significantly higher.

4. Inflammation

Women with PCOS often have increased levels of low-grade inflammation, which may stimulate polycystic ovaries to produce androgens.

Diagnosis of PCOS

Diagnosis typically requires meeting at least two of the following three criteria (Rotterdam criteria):

1. Irregular or absent ovulation

2. Clinical or biochemical signs of elevated androgens

3. Polycystic ovaries on ultrasound

Diagnostic Tests Include:

• Detailed medical history and physical examination
• Blood tests for hormone levels (FSH, LH, testosterone, DHEAS)
• Glucose tolerance test and insulin levels
• Lipid profile
• Pelvic ultrasound

Treatment Options for PCOS

Treatment is tailored to individual symptoms and goals, whether managing symptoms, improving fertility, or preventing long-term complications.

Lifestyle Modifications

Lifestyle changes are the first-line treatment for PCOS:

• Healthy diet: Focus on whole grains, lean proteins, vegetables, and low-glycemic foods
• Regular exercise: Aim for 150 minutes of moderate activity weekly
• Weight management: Even a 5-10% weight loss can significantly improve symptoms
• Stress reduction: Practice yoga, meditation, or other relaxation techniques

Medical Treatments

For Menstrual Regulation:

• Combined oral contraceptives to regulate periods and reduce androgen levels
• Progestin therapy to induce regular periods

For Insulin Resistance:

• Metformin to improve insulin sensitivity and may help with weight management

For Excess Hair Growth and Acne:

• Anti-androgen medications (spironolactone)
• Topical treatments for acne
• Hair removal methods (laser, electrolysis)

For Fertility:

• Ovulation induction with medications like letrozole or clomiphene
• Gonadotropin injections if oral medications don't work
• Laparoscopic ovarian drilling in selected cases
• IVF for women who don't respond to other treatments

Surgical Options

Laparoscopic ovarian drilling is a minimally invasive procedure where small holes are made in the ovaries to reduce androgen production and restore ovulation.

Long-Term Health Considerations

Women with PCOS have an increased risk of:

• Type 2 diabetes
• Cardiovascular disease
• Endometrial cancer (due to irregular periods)
• Sleep apnea
• Depression and anxiety

Regular monitoring and proactive management are essential for long-term health.

Frequently Asked Questions

Can PCOS be cured?

While PCOS cannot be cured, it can be effectively managed through lifestyle modifications and medical treatment. Many women successfully manage their symptoms and lead healthy, fulfilling lives.

Can I get pregnant with PCOS?

Yes, many women with PCOS conceive successfully with proper treatment. Ovulation-inducing medications and lifestyle changes significantly improve fertility outcomes.

Does PCOS go away after menopause?

While some symptoms like irregular periods resolve after menopause, the metabolic aspects of PCOS (insulin resistance, increased cardiovascular risk) may persist and require ongoing management.

What foods should I avoid with PCOS?

Limit refined carbohydrates, sugary foods, processed foods, and excessive saturated fats. Focus on whole, unprocessed foods with a low glycemic index.

How often should I see my doctor for PCOS?

Regular follow-ups every 3-6 months are recommended, or more frequently if you're trying to conceive or adjusting medications.
