@fertility.theory: PCOS has now been renamed PMOS 🎉 Polyendocrine Metabolic Ovarian Syndrome After 14 years of advocacy, polycystic ovary syndrome is now officially polyendocrine metabolic ovarian syndrome, or PMOS. 

The change was announced in Prague and published in The Lancet this week.
 So why does the name matter? 

Because the old name was misleading. 
“Polycystic” implied cysts were the defining feature, but most people with this condition don’t have abnormal cysts. 

What they do have is a complex hormonal and metabolic disorder that affects around 1 in 8 women and takes up to 12 years on average to diagnose.
 That 12-year figure is not okay.
 The new name shifts the focus to what’s actually happening in the body: dysregulated endocrine function and metabolic disruption. 

This means doctors can now diagnose based on the full picture: irregular cycles, acne, difficulty losing weight, insulin resistance, and more, without needing to rely on ovarian cyst findings as a primary criterion.
 For people already diagnosed: your experience is valid, and this name change reflects what your body has been telling you all along.
 For people still searching for answers: 
this could be the shift that finally gets you seen.
 The full transition to PMOS rolls out over three years, with international guidelines to be updated in 2028. 

Research, clinical practice, and awareness campaigns are all set to follow.
 This is a big deal. And it’s long overdue. #PCOS #PCOSnamechange #PMOS #pcos #pcosweightloss
