The problem

Turn what you feel into something you can see

PMOS (Polyendocrine Metabolic Ovarian Syndrome), renamed from PCOS (Polycystic Ovary Syndrome) in 2026, is the most common endocrine condition among people of reproductive age. It affects hormones, metabolism, mood, and fertility all at once, and it shows up differently in almost everyone who has it.

170M
people affected worldwide, more than 1 in 8 who menstruate
~70%
go undiagnosed worldwide, as many as 3 in 4 by some estimates (WHO)
4.3 yrs
average wait from first symptoms to a diagnosis
27
mean age at diagnosis in the U.S., often years after symptoms begin

The gap isn't the patient's fault. PMOS symptoms span hormonal, metabolic, neurological, and reproductive systems, and rarely present the same way twice. Many people are told it's stress, anxiety, or something they'll grow out of, and nearly half see three or more providers before anyone connects the dots. The pattern is usually clear to the person living it long before it's visible to a provider seeing one symptom at a time, across separate visits.

See what's actually working for you

Most people managing PMOS piece together their own mix of supplements, medications, and lifestyle changes. Vega tracks it all with morning and evening (AM/PM) check-ins, then shows the before-and-after impact, so you can tell what's helping from what isn't.
