What is the Difference Between PCOD and PCOS?

Polycystic Ovary Disorder (PCOD) and Polycystic Ovary Syndrome (PCOS) are two commonly confused conditions that affect women’s reproductive health. Despite their similar names, they have distinct differences in terms of their symptoms, causes, and management. Understanding these differences is crucial for women who are diagnosed with either condition to receive appropriate care and treatment. In this blog, we will explore what PCOD and PCOS are, their symptoms, causes, diagnosis, and treatment options, and how they differ from each other.

What is PCOD?

PCOD, or Polycystic Ovary Disorder, is a condition where the ovaries produce a large number of immature or partially mature eggs. These eggs develop into cysts over time. Women with PCOD often experience hormonal imbalances that can lead to various symptoms, but it is generally considered less severe than PCOS.

Symptoms of PCOD

Women with PCOD may experience a range of symptoms, including:

  • Irregular menstrual cycles.
  • Weight gain, particularly around the abdomen.
  • Mild hirsutism (excessive hair growth).
  • Acne and oily skin.
  • Thinning hair or hair loss.
  • Difficulty conceiving due to irregular ovulation.

Causes of PCOD

The exact cause of PCOD is not fully understood, but it is believed to involve a combination of genetic and environmental factors. Key contributors include:

  • Hormonal Imbalance: Excess production of androgens (male hormones) by the ovaries can disrupt the development and release of eggs.
  • Insulin Resistance: Elevated insulin levels can lead to an overproduction of androgens, contributing to the symptoms of PCOD.
  • Genetics: A family history of PCOD can increase the likelihood of developing the condition.

Diagnosis of PCOD

Diagnosing PCOD typically involves:

  • Medical History and Physical Exam: A detailed medical history and physical examination to assess symptoms and risk factors.
  • Ultrasound: Imaging tests, such as pelvic ultrasound, to visualize the ovaries and identify the presence of cysts.
  • Blood Tests: Hormonal tests to measure levels of androgens, insulin, and other relevant hormones.

Treatment of PCOD

The treatment of PCOD focuses on managing symptoms and may include:

  • Lifestyle Changes: A balanced diet, regular exercise, and weight management can help regulate menstrual cycles and improve overall health.
  • Medications: Birth control pills to regulate menstrual cycles, anti-androgens to reduce hirsutism and acne, and medications to improve insulin sensitivity.
  • Fertility Treatments: For women experiencing difficulty conceiving, fertility medications or assisted reproductive technologies (ART) may be recommended.

Understanding PCOS

What is PCOS?

PCOS, or Polycystic Ovary Syndrome, is a more severe and complex condition than PCOD. It is a hormonal disorder characterized by the presence of multiple cysts in the ovaries, irregular menstrual cycles, and elevated levels of androgens. PCOS is a leading cause of infertility in women.

Symptoms of PCOS

The symptoms of PCOS are often more pronounced and varied than those of PCOD, and can include:

  • Irregular or absent menstrual periods.
  • Severe hirsutism (excessive hair growth on the face, chest, and back).
  • Severe acne and oily skin.
  • Significant weight gain and difficulty losing weight.
  • Scalp hair thinning or male-pattern baldness.
  • Darkening of the skin, particularly around the neck and under the breasts.
  • Skin tags in the armpits or neck area.
  • Difficulty conceiving and recurrent miscarriages.

Causes of PCOS

Similar to PCOD, the exact cause of PCOS is unknown, but it is believed to be influenced by genetic, hormonal, and environmental factors. Key contributors include:

  • Hormonal Imbalance: Elevated levels of androgens disrupt the normal menstrual cycle and prevent the ovaries from releasing eggs regularly.
  • Insulin Resistance: High levels of insulin can increase androgen production, exacerbating PCOS symptoms.
  • Inflammation: Chronic low-grade inflammation is common in women with PCOS, which can contribute to increased androgen levels.

Diagnosis of PCOS

Diagnosing PCOS typically involves:

  • Medical History and Physical Exam: A thorough review of symptoms, menstrual history, and physical examination.
  • Ultrasound: Pelvic ultrasound to check for the presence of multiple ovarian cysts and assess ovarian volume.
  • Blood Tests: Hormonal tests to measure levels of androgens, insulin, and other relevant hormones. Tests may also be conducted to rule out other conditions with similar symptoms.

Treatment of PCOS

Treatment for PCOS is aimed at managing symptoms, improving fertility, and reducing the risk of complications. It may include:

  • Lifestyle Changes: Weight management through a healthy diet and regular exercise is crucial. Reducing insulin resistance through diet and physical activity can improve symptoms.
  • Medications: Birth control pills to regulate menstrual cycles, anti-androgens to reduce hirsutism and acne, and insulin-sensitizing drugs like metformin.
  • Fertility Treatments: For women struggling with infertility, medications to stimulate ovulation, such as clomiphene citrate, or ART like in vitro fertilization (IVF).
  • Management of Complications: Regular monitoring and treatment for related conditions such as type 2 diabetes, cardiovascular disease, and sleep apnea.

Key Differences Between PCOD and PCOS

While PCOD and PCOS share similarities, they have distinct differences that affect diagnosis, treatment, and overall health outcomes.

1. Severity

  • PCOD: Generally considered a milder form of hormonal imbalance. Symptoms can often be managed with lifestyle changes and medication.
  • PCOS: A more severe condition with a broader range of symptoms and associated health risks, including a higher risk of metabolic and cardiovascular disorders.

2. Hormonal Imbalance

  • PCOD: Hormonal imbalances are present but usually less severe. The ovaries produce a higher number of immature or partially mature eggs, leading to cysts.
  • PCOS: Significant hormonal imbalance with elevated androgen levels, which disrupt normal ovulation and cause more pronounced symptoms.

3. Impact on Fertility

  • PCOD: Women with PCOD can often conceive with minor assistance, as ovulation occurs more regularly than in PCOS.
  • PCOS: Infertility is a common issue due to irregular ovulation or anovulation. More intensive fertility treatments are often required.

4. Associated Health Risks

  • PCOD: Fewer long-term health risks, but it can lead to obesity and associated complications if not managed properly.
  • PCOS: Increased risk of developing type 2 diabetes, cardiovascular disease, endometrial cancer, and metabolic syndrome due to chronic hormonal imbalance and insulin resistance.

5. Diagnosis Criteria

  • PCOD: Diagnosis is primarily based on ultrasound findings of multiple cysts in the ovaries and a review of symptoms.
  • PCOS: Diagnosis involves a combination of ultrasound, blood tests, and a thorough review of symptoms and medical history, following criteria such as the Rotterdam criteria, which require at least two of the following: irregular periods, excess androgen levels, and polycystic ovaries.

6. Treatment Approaches

  • PCOD: Focus on symptom management through lifestyle changes and medication. Fertility treatments may be needed but are generally less intensive.
  • PCOS: Requires a comprehensive approach that addresses multiple symptoms and associated health risks. Treatment often includes lifestyle changes, medications, and potentially more intensive fertility treatments.


Understanding the differences between PCOD and PCOS is crucial for effective management and treatment. While both conditions involve hormonal imbalances and ovarian cysts, they differ significantly in severity, symptoms, impact on fertility, and associated health risks. Women experiencing symptoms of either condition should seek medical advice for accurate diagnosis and appropriate treatment.

Managing these conditions often involves a combination of lifestyle changes, medication, and in some cases, fertility treatments. By staying informed and working closely with healthcare providers, women with PCOD or PCOS can effectively manage their symptoms and maintain a healthy, balanced life.
