PCOS Will Now Be Called PMOS: Know Why Experts Changed the Name

The common hormonal disorder previously known as Polycystic Ovary Syndrome (PCOS) is now being renamed Polyendocrine Metabolic Ovarian Syndrome by many global medical experts. The change was announced after years of international research and discussion.

Why was the name changed?

The old name “PCOS” was considered misleading for several reasons:

1. Not all patients have ovarian cysts
   Many women diagnosed with PCOS do not actually have cysts in their ovaries. The “cysts” seen in scans are often immature follicles, not true cysts.
2. The disease affects much more than ovaries
   Doctors now recognize that the condition impacts the entire body, including:
   • Hormones
   • Metabolism
   • Insulin resistance
   • Weight
   • Heart health
   • Mental health
   • Fertility
     The old name focused only on ovaries and ignored these major effects.
3. Many women were misdiagnosed or diagnosed late
   Because the name emphasized “cysts,” some patients without visible cysts were told they did not have the condition, delaying treatment.
4. The new name explains the disease better
   PMOS stands for:
   • Polyendocrine → affects multiple hormone systems
   • Metabolic → linked to metabolism and insulin resistance
   • Ovarian Syndrome → still connected to ovarian function
   This gives a more complete picture of the disorder.

What changes for patients?

• Symptoms and treatment remain mostly the same for now.
• Doctors hope the new name will:
  • improve awareness,
  • reduce stigma,
  • help earlier diagnosis,
  • and encourage better long-term treatment and research.

Around 170 million women worldwide are affected by this condition, and experts believe the name change could improve healthcare understanding globally.
