What is PCOS? Symptoms, Causes, and Diagnosis

By /

Polycystic Ovary Syndrome (PCOS) is one of the most common hormonal disorders affecting women of reproductive age worldwide, and India is no exception. In recent years, PCOS has gained significant attention in India due to its rising prevalence, particularly among young women in urban areas. This blog explores what PCOS is, its symptoms, causes, and how it is diagnosed, with a special focus on the Indian context. Whether you’re seeking to understand PCOS for yourself or a loved one, this guide aims to provide clear, actionable information.

WHAT IS PCOS?

Polycystic Ovary Syndrome, commonly known as PCOS or PCOD (Polycystic Ovary Disease), is a hormonal condition that affects women, typically during their reproductive years (ages 15–44). It is characterized by an imbalance in reproductive hormones, leading to a range of symptoms and potential health complications. The term “polycystic” refers to the presence of multiple small cysts (fluid-filled sacs) on the ovaries, which can be detected through imaging tests. However, not all women with PCOS have cysts, and the condition is primarily defined by hormonal and metabolic irregularities.

In India, PCOS is increasingly prevalent, with studies estimating that 10–22% of women of reproductive age are affected, depending on the diagnostic criteria used. Urbanization, changing lifestyles, and genetic predispositions are contributing to this rise. PCOS can impact fertility, physical health, and emotional well-being, making early diagnosis and management crucial.

SYMPTOMS OF PCOS

PCOS manifests through a variety of symptoms, which can vary in severity from person to person. The condition is often diagnosed when a woman exhibits at least two of the following three criteria (known as the Rotterdam criteria):

  1. Irregular or Absent Menstrual Cycles: Women with PCOS often experience irregular periods, which may be infrequent (fewer than eight periods a year), prolonged, or absent altogether. This is due to irregular ovulation or anovulation (lack of ovulation), which disrupts the menstrual cycle.
  2. Hyperandrogenism (Excess Male Hormones): Elevated levels of androgens (male hormones like testosterone) can lead to symptoms such as:
    • Hirsutism: Excessive hair growth on the face, chest, back, or other areas where men typically grow hair.
    • Acne: Persistent acne, especially on the face, chest, or upper back, often resistant to standard treatments.
    • Hair Loss: Thinning hair or male-pattern baldness (alopecia) on the scalp.
  3. Polycystic Ovaries: An ultrasound may reveal enlarged ovaries with multiple small cysts, although this is not always present in PCOS cases.

In addition to these core symptoms, women with PCOS may experience:

  • Weight Gain: Many women with PCOS struggle with weight gain or difficulty losing weight, often due to insulin resistance, a common feature of the condition.
  • Skin Changes: Darkening of the skin (acanthosis nigricans), particularly in areas like the neck, armpits, or groin, is a sign of insulin resistance.
  • Infertility: Irregular ovulation can make it challenging to conceive, making PCOS one of the leading causes of infertility in women.
  • Mood Disorders: Anxiety, depression, and mood swings are common, partly due to hormonal imbalances and the emotional toll of managing symptoms.
  • Fatigue: Chronic fatigue or low energy levels may occur, often linked to insulin resistance or poor sleep quality.
  • Sleep Issues: Some women with PCOS experience sleep apnea or other sleep disturbances.

In India, symptoms like hirsutism and irregular periods are often the first signs that prompt women to seek medical advice. However, cultural stigmas around discussing reproductive health can delay consultations, leading to complications.

CAUSES OF PCOS

The exact cause of PCOS is not fully understood, but it is believed to result from a combination of genetic, hormonal, and environmental factors. Here are the primary contributors:

1. Hormonal Imbalance

PCOS is driven by an imbalance in reproductive hormones, particularly:

  • Elevated Androgens: Higher-than-normal levels of male hormones disrupt ovulation and lead to symptoms like hirsutism and acne.
  • Insulin Resistance: Many women with PCOS have insulin resistance, where the body’s cells do not respond effectively to insulin. This leads to elevated insulin levels, which can stimulate the ovaries to produce more androgens, exacerbating PCOS symptoms.
  • Luteinizing Hormone (LH) and Follicle-Stimulating Hormone (FSH) Imbalance: An abnormal LH-to-FSH ratio can interfere with ovulation, contributing to irregular periods and cyst formation.

2. Genetic Factors

PCOS tends to run in families, suggesting a genetic component. If a woman’s mother, sister, or aunt has PCOS, her risk of developing the condition is higher. In India, studies have identified certain genetic markers associated with PCOS, particularly in South Asian populations, which may explain its higher prevalence in the region.

3. Lifestyle and Environmental Factors

Modern lifestyles, especially in urban India, play a significant role in PCOS development:

  • Sedentary Lifestyle: Lack of physical activity contributes to weight gain and insulin resistance, both of which worsen PCOS symptoms.
  • Poor Diet: Diets high in refined carbohydrates, sugars, and processed foods can exacerbate insulin resistance. In India, the shift toward Westernized diets with fast food and sugary beverages has been linked to rising PCOS cases.
  • Stress: Chronic stress, common in fast-paced urban environments, can disrupt hormonal balance and aggravate PCOS symptoms.
  • Obesity: While obesity does not cause PCOS, excess body weight can worsen symptoms, creating a vicious cycle. In India, obesity rates are rising, particularly among young women, contributing to the PCOS epidemic.

4. Inflammation

Low-grade chronic inflammation is often observed in women with PCOS, which may contribute to insulin resistance and androgen excess. This inflammation can be influenced by diet, stress, and other lifestyle factors.

DIAGNOSIS OF PCOS

Diagnosing PCOS involves a combination of medical history, physical examination, blood tests, and imaging. In India, the process typically follows these steps:

1. Medical History and Symptom Assessment

A doctor will ask about:

  • Menstrual cycle patterns (e.g., irregular or absent periods).
  • Symptoms of hyperandrogenism (e.g., hirsutism, acne, or hair loss).
  • Family history of PCOS, diabetes, or other hormonal disorders.
  • Lifestyle factors, such as diet, exercise, and stress levels.

In India, women may not always report symptoms like irregular periods due to cultural sensitivities, so doctors often rely on open-ended questions to gather information.

2. Physical Examination

The doctor may check for physical signs of PCOS, such as:

  • Excessive hair growth or acne.
  • Signs of insulin resistance, like acanthosis nigricans (darkened skin patches).
  • Body mass index (BMI) to assess weight-related risks.

3. Blood Tests

Blood tests are used to measure hormone levels and rule out other conditions with similar symptoms (e.g., thyroid disorders). Common tests include:

  • Testosterone and Other Androgens: To check for elevated male hormone levels.
  • LH and FSH: To assess the LH-to-FSH ratio, which is often elevated in PCOS.
  • Insulin and Glucose Levels: To evaluate insulin resistance or diabetes risk.
  • Prolactin and Thyroid Hormones: To rule out other causes of irregular periods.

In India, access to advanced hormonal testing may be limited in rural areas, but urban diagnostic centers typically offer these tests.

4. Pelvic Ultrasound

An ultrasound is used to visualize the ovaries and check for:

  • Multiple small cysts (follicles) on the ovaries.
  • Enlarged ovaries.
  • Thickened endometrial lining (due to irregular periods).

In India, ultrasound is widely available in urban hospitals and clinics, but the quality of imaging and interpretation may vary in smaller facilities.

5. Rotterdam Criteria

Most doctors in India use the Rotterdam criteria for diagnosis, which require at least two of the following:

  • Irregular or absent ovulation.
  • Signs of hyperandrogenism (clinical or biochemical).
  • Polycystic ovaries on ultrasound.

Challenges in Diagnosis

In India, diagnosing PCOS can be challenging due to:

  • Lack of Awareness: Many women are unaware of PCOS symptoms or dismiss them as normal, delaying diagnosis.
  • Misdiagnosis: Symptoms like irregular periods or acne may be attributed to other causes, such as stress or poor skincare.
  • Variable Healthcare Access: Rural women may lack access to specialized gynecologists or diagnostic tools, leading to underdiagnosis.

PCOS MANAGEMENT

While PCOS is a chronic condition with no cure, it can be managed effectively with lifestyle changes, medical treatment, and support. Here are some strategies commonly recommended in India:

1. Lifestyle Modifications

  • Diet: A balanced diet rich in whole grains, vegetables, lean proteins, and healthy fats can help manage insulin resistance and weight. In India, incorporating traditional foods like millets, lentils, and fresh produce can be beneficial.
  • Exercise: Regular physical activity (e.g., yoga, walking, or strength training) can improve insulin sensitivity and reduce symptoms. Yoga, deeply rooted in Indian culture, is particularly effective for stress management and hormonal balance.
  • Weight Management: Losing even 5–10% of body weight can significantly improve PCOS symptoms, including menstrual regularity and fertility.

2. Medical Treatments

  • Hormonal Contraceptives: Birth control pills are often prescribed to regulate periods and reduce androgen levels.
  • Anti-Androgens: Medications like spironolactone can help manage hirsutism and acne.
  • Metformin: This insulin-sensitizing drug is commonly used to address insulin resistance.
  • Fertility Treatments: For women trying to conceive, medications like clomiphene or letrozole may be prescribed to induce ovulation.

In India, these treatments are widely available in urban areas, but affordability and access can be issues in rural regions.

3. Mental Health Support

PCOS can take a toll on mental health due to symptoms like infertility, weight gain, or hirsutism. Counseling or support groups can help women cope with emotional challenges. In India, online support communities and teleconsultations are becoming popular for addressing mental health concerns.

4. Traditional and Alternative Therapies

In India, some women turn to Ayurveda, homeopathy, or naturopathy for PCOS management. While these approaches may offer benefits like stress reduction, they should complement, not replace, evidence-based medical care.
