You may have heard of PCOS (polycystic ovary syndrome), a condition affecting about 1 in 10 women.*
As of May 2026, PCOS has a new name: PMOS (polyendocrine metabolic ovarian syndrome). This change is meant to help patients find clarity and support, earlier and more easily.
PCOS was misleading because it doesn’t accurately capture the nature of the condition. It centered on ovarian cysts – although they are not the main feature. In contrast, PMOS emphasizes the condition’s hormonal and metabolic nature.
“For decades, the name ‘polycystic ovary syndrome’ pointed patients and providers toward ovarian ‘cysts’ that aren’t actually cysts at all. That misdirection contributed to delayed diagnoses, with studies suggesting that up to 70% of affected individuals go unrecognized,” says Dr. Nicole M. Marchetto, an OB/GYN and reproductive endocrinologist at Shady Grove Fertility.
“The new name gives patients and their care teams a clearer starting point so the right conversations happen sooner.”
Women with PMOS often struggle to get diagnosed. Healthcare providers may think of it as a gynecological condition, but its root cause is hormonal. Misunderstanding may delay effective, comprehensive treatment. As Dr. Marchetto explains, PMOS better reflects the wide-ranging effects on physical and emotional health:
“PMOS is not just a reproductive condition – it’s a multisystem syndrome. Individuals with PMOS face elevated risks of type 2 diabetes, cardiovascular disease, and mental health challenges including anxiety and depression. The new name signals that comprehensive screening and long-term health monitoring matter just as much as managing cycles or fertility.”
PMOS experiences vary, and not everyone has the same symptoms. The most common include:
When PMOS isn’t treated effectively, it may raise other health risks, including:
Fortunately, early diagnosis and care help reduce risks and improve well-being. Personalized care plans for PMOS may include:
Dr. Marchetto stresses that individualized, comprehensive care is essential. “The best outcomes happen when patients have a coordinated care team that sees the full picture, not just one piece of it.”
