Context: Medical experts, including those from AIIMS Delhi, highlighted a landmark global shift in medical terminology where Polycystic Ovary Syndrome (PCOS) is being renamed to Polyendocrine Metabolic Ovarian Syndrome (PMOS).
About Polyendocrine Metabolic Ovarian Syndrome (PMOS):
What was PCOS?
- Polycystic Ovary Syndrome (PCOS) was traditionally understood as a reproductive disorder characterized by irregular periods, excess androgens (masculine hormones), and the appearance of cysts on the ovaries.
- However, the term was medically inaccurate as the cysts are actually arrested follicles (immature eggs that failed to mature and release) rather than true pathological cysts.
What is PMOS?
- PMOS is the updated medical term that identifies the condition as a multisystemic disorder. It acknowledges that the syndrome involves the endocrine (hormonal), metabolic (energy processing), reproductive, and psychological systems of the body.
Causes for PMOS:
While the exact cause is complex, it is generally attributed to a combination of:
- Insulin Resistance: The body’s cells don’t respond normally to insulin, causing blood sugar levels to rise and the body to produce more insulin, which in turn triggers excess androgen production.
- Hormonal Imbalance: Elevated levels of androgens and Luteinizing Hormone (LH) disrupt the normal ovulation cycle.
- Genetics: A strong hereditary link, particularly significant in the Indian population.
- Low-grade Inflammation: Research suggests women with this condition have a type of low-grade inflammation that stimulates polycystic ovaries to produce androgens.
Symptoms and Impacts:
| Category | Manifestations & Impacts |
| Reproductive | Irregular or absent periods, infertility, pregnancy complications, and an increased risk of endometrial cancer. |
| Metabolic | Weight gain (obesity), Type 2 diabetes, hypertension (high blood pressure), and fatty liver disease (MASLD). |
| Dermatological | Severe acne, thinning of scalp hair (alopecia), and hirsutism (excessive facial or body hair). |
| Psychological | Increased rates of anxiety, depression, eating disorders, and poor quality of life due to physical symptoms. |
Difference Between PCOS and PMOS:
| Basis | PCOS (Polycystic Ovary Syndrome) | PMOS (Polyendocrine Metabolic Ovary Syndrome) |
| Focus | Mainly focused on ovaries and reproductive symptoms | Focuses on endocrine and metabolic dysfunction across the body |
| Terminology | Cystic term may be misleading | Metabolic and Polyendocrine better reflect root causes |
| Disease Nature | Viewed largely as a gynecological disorder | Recognized as a systemic metabolic condition |
| Clinical Approach | Treatment often centered on fertility and menstruation | Includes early screening for diabetes, obesity, and heart disease |
| Patient Clarity | Confusing for patients without ovarian cysts | Gives clearer understanding of hormonal and metabolic involvement |
