The Lancet just officially renamed PCOS (polycystic ovarian syndrome) to PMOS (polyendocrine metabolic ovarian syndrome) — and here’s what it means for our teenage daughters.
For 90 years, we’ve been calling it the wrong name. This week, that changed. 14 years of global consensus. 56 organizations. 14,360 patient and clinician voices. And one truth so obvious it almost didn’t make it to print:
This was never just an o***y problem. It’s a multi-system problem.
Most teenage girls get missed.
✨75% of lean teens with PMOS have insulin resistance — even with a “normal” BMI. They’re the girls being told their irregular cycles are “stress” or their acne will “pass.” They deserve so much more.
And at the root, lies the gut microbiome.
✨ The microbiome sits at the root of nearly every PMOS driver. Insulin resistance. Androgens. Inflammation. Mood.
🎉The good news? Most root causes of PMOS are modifiable.
👉Swipe through for the evidence-backed interventions I recommend for my teenage patients — food, inositol, sleep, movement, stress and mental health support, and reducing microbiome-disrupting chemicals (yes — endocrine disruptors are also microbiome disruptors. That’s why they have negative effects far beyond hormones).
👉Save and send this to a mom or teen in need. Share with your pediatrician.
This is the new paradigm. This is how our teenage daughters become empowered to make the choices that help them thrive!
📚For the foundational microbiome science behind everything in this carousel — including the framework I use with every patient — see my book Healthy Kids, Happy Kids. Link in Bio or comment “BOOK” below and I’ll DM you the link.
💩And in case you’re wondering how to know if your daughter’s microbiome needs support, .health is the ONLY gut microbiome test I recommend for all ages. (Disclosure: I believe in Tiny Health so much that I am proud to serve as Chief Medical Officer).
Knowledge is power.
