In recent years, discussions around women’s hormonal health have gained remarkable momentum across India. Yet, amidst this growing awareness, a cloud of confusion continues to surround two terms that are frequently used interchangeably: PMOS and PCOD. For countless Indian women navigating irregular periods, unexplained weight gain, or fertility concerns, understanding the distinction between these conditions is not merely an academic exercise, it is the first step toward reclaiming their health and well-being.

This article aims to demystify these terms, drawing upon authoritative medical sources, to provide Indian women with the clarity they deserve.

Understanding PMOS: The New Medical Terminology

PMOS stands for Polyendocrine Metabolic Ovarian Syndrome. In May 2026, following a global expert consensus announced at the European Congress of Endocrinology and published in The Lancet, the condition formerly known as Polycystic Ovary Syndrome (PCOS) was officially renamed PMOS. This was not merely a cosmetic change but a deliberate shift to reflect a deeper understanding of the condition.

As defined by Mayo Clinic, PMOS is a hormone health issue that begins to show signs in women of childbearing age, characterised by irregular periods, excess androgen (male hormone) levels, and the presence of multiple small fluid-filled sacs (follicles) on the ovaries. Cleveland Clinic further explains that PMOS is a hormonal imbalance where the ovaries produce unusually high levels of androgens, leading to irregular menstrual cycles, missed periods, and unpredictable ovulation.

Johns Hopkins Medicine emphasises that PMOS is “a set of symptoms caused by a problem with a woman’s hormones” that affects not only the ovaries but the entire body. This holistic understanding is precisely why the name was changed, to move beyond the misconception that the condition is solely an ovarian problem.

Understanding PCOD: The Older, Familiar Term

PCOD, or Polycystic Ovarian Disease, is an older term that remains widely used in India. It was first described in 1935 by Stein and Leventhal, who documented a case series of seven women presenting with irregular periods, obesity, excess hair growth, and enlarged ovaries containing multiple cysts.

According to the Apollo Hospitals, PCOD occurs when the ovaries produce immature or partially mature eggs, which can form cysts over time. This condition leads to hormonal imbalances but is generally considered less severe than the systemic syndrome that PMOS represents.

The National Institutes of Health (NIH) notes that PCOD (polycystic ovarian disease) is diagnosed when polycystic ovaries are associated with chronic anovulation (lack of ovulation) and clinical or biochemical evidence of excess androgens. However, as PMC (PubMed Central) articles clarify, the term “PCOD” is now the least used term in medical literature because it fails to capture the full complexity of the condition.

The Critical Difference: PMOS vs PCOD

While PMOS and PCOD are often used interchangeably in everyday conversations, medical experts emphasise that they are not exactly the same condition. Understanding this distinction is vital for Indian women seeking appropriate care.

1. Nature of the Condition

PCOD is primarily viewed as an ovarian-focused condition, a functional disorder where the ovaries release immature eggs, leading to cyst formation and mild hormonal imbalances. It is typically described as having ovarian-related features with irregular cycles.

PMOS, by contrast, is a systemic endocrine and metabolic syndrome that extends far beyond the ovaries. It affects multiple body systems, including hormonal regulation, metabolism, and even cardiovascular health. As Dr Kinjal Avdhut Kothari, Consultant of Obstetrics and Gynaecology at Manipal Hospital, explains: “PMOS refers to the full syndrome with clear hormonal and metabolic features”.

2. Severity and Scope

PCOD is generally milder. Women with PCOD experience mild to moderate symptoms that can often be managed with lifestyle changes and minimal medical intervention. It rarely leads to infertility, and most women with PCOD can conceive with little or no medical assistance.

PMOS is more severe and complex. It is characterised by significant androgen excess, insulin resistance, and metabolic abnormalities. Women with PMOS often require comprehensive medical treatment alongside lifestyle modifications. The condition is associated with higher risks of type 2 diabetes, hypertension, cardiovascular disease, and endometrial cancer.

3. Prevalence Among Indian Women

The distinction between these terms carries particular significance for Indian women. Studies estimate that between 9% and 22% of Indian women suffer from PCOD or PCOS/PMOS, rates significantly higher than those reported in many other countries.

More strikingly, approximately 1 in 5 Indian women of reproductive age may be affected by PMOS or PCOD in some form. Indian women have nearly double the prevalence and experience earlier onset compared to the global average. The South Asian phenotype, documented across decades of research, describes a body that stores more visceral fat at any given BMI than European or East Asian populations, making Indian women particularly vulnerable to the metabolic complications of PMOS.

Why the Name Change Matters for Indian Women

The transition from PCOS to PMOS is more than a semantic exercise, it carries profound implications for how Indian women understand and manage their health.

The new name PMOS accurately reflects that this is a whole-body hormonal and metabolic disorder, not merely an ovarian issue. It highlights the metabolic, ovarian, and polyendocrine aspects of the condition, encouraging a more holistic approach to treatment.

“PMOS signifies it is not a condition which is just confined to ovaries, but it is a metabolic disease affecting various endocrine systems, thus making one understand that it is a great opportunity to provide holistic services to patients by involving physicians, endocrinologists, gynaecologists, and nutritional experts”.

Recognising the Symptoms: What Indian Women Should Watch For

Both PMOS and PCOD share overlapping symptoms, but the severity and range of symptoms differ significantly.

Common Symptoms of PCOD:

• Irregular menstrual cycles
• Weight gain
• Acne and oily skin
• Hair thinning
• Fatigue

Common Symptoms of PMOS:

• Irregular or absent periods: You may have fewer than eight periods a year, with cycles more than 35 days apart
• Excess androgen effects: This includes hirsutism (excess hair on the face, chin, chest, back, or abdomen), severe acne, and male-pattern hair loss
• Polycystic ovaries: Ovaries may be enlarged with multiple small follicles visible on ultrasound
• Weight gain, particularly around the abdomen
• Infertility or difficulty conceiving
• Insulin resistance and metabolic disturbances
• Skin changes: Dark or thick skin patches on the neck, armpits, or under the breasts (acanthosis nigricans), and skin tags

When to See a Doctor

Mayo Clinic advises seeking medical attention if you are worried about your periods, having trouble getting pregnant, or experiencing symptoms of excess androgen such as new hair growth on the face and body, acne, or male-pattern hair loss.

Causes and Risk Factors

The exact cause of PMOS remains unknown, but several factors contribute to its development.

Insulin Resistance: A key factor in PMOS is insulin resistance and the body’s inability to use insulin effectively. This leads to elevated insulin levels, which in turn stimulate the ovaries to produce more androgens.

Genetics: A family history of PMOS increases your risk. If your mother or sister has the condition, you are more likely to develop it.

Obesity: Excess weight can worsen insulin resistance and exacerbate PMOS symptoms.

Lifestyle Factors: Among Indian women, urban lifestyles characterised by poor diet, stress, and lack of physical activity contribute significantly to the rising prevalence of these conditions.

Diagnosis: How PMOS and PCOD Are Identified

Diagnosis typically involves a combination of approaches:

Medical History and Physical Examination: Your healthcare provider will ask about your menstrual history, symptoms, and family history, and perform a pelvic examination.

Ultrasound: This imaging test examines the size of your ovaries and checks for the presence of multiple follicles or cysts.

Blood Tests: These measure hormone levels, including androgens, as well as blood glucose, cholesterol, and triglyceride levels.

A diagnosis of PMOS is typically made when at least two of three criteria are present: irregular periods, signs of excess androgen, and polycystic ovaries on ultrasound.

Treatment and Management: A Holistic Approach

While there is no cure for PMOS, its symptoms can be effectively managed. Treatment is individualised and depends on your symptoms, overall health, and whether you wish to become pregnant.

Lifestyle Modifications

Lifestyle changes are the cornerstone of managing both PCOD and PMOS. Even a 5–10% reduction in body weight can lead to significant improvements in symptoms.

• Healthy Diet: Focus on a balanced diet rich in whole grains, lean proteins, fruits, and vegetables. Reduce intake of simple carbohydrates and processed foods.
• Regular Exercise: Aim for at least 30 minutes of moderate physical activity most days of the week.
• Adequate Sleep: Good sleep hygiene supports hormonal balance.
• Stress Management: Chronic stress can exacerbate hormonal imbalances.

Medical Treatments

• Hormonal Contraceptives: Birth control pills can regulate menstrual cycles, reduce acne, and decrease excess hair growth.
• Insulin-Sensitising Medications: Metformin improves insulin sensitivity and can help regulate cycles and support weight management.
• Fertility Treatments: For women trying to conceive, fertility medications or assisted reproductive technologies may be recommended.
• Anti-Androgen Medications: These can reduce excess hair growth and acne.

Regular Monitoring

Regular health check-ups are essential to monitor blood sugar, cholesterol, and blood pressure levels, helping to prevent long-term complications such as diabetes and heart disease.

A Message of Hope for Indian Women

If you have been diagnosed with PCOD or PMOS, please know that you are not alone. These conditions affect millions of Indian women, and with proper management, you can lead a healthy, fulfilling life.

The renaming of PCOS to PMOS is a step forward, it signals a more comprehensive understanding of the condition and paves the way for better, more holistic care. By understanding the difference between PCOD and PMOS, you empower yourself to seek the right diagnosis, the right treatment, and the right support.

Your health journey begins with awareness. Listen to your body, pay attention to changes in your menstrual cycle, and do not hesitate to consult a healthcare professional. Early diagnosis and proactive management can make all the difference.
