Key Questions

Why is PCOS being renamed to PMOS?

How will the PMOS name change affect screening and treatment?

It supports broader screening for diabetes and cardiovascular risk. The shift also aligns management more closely with diet-based approaches.

Who is contributing to PMOS diet guidance?

Melinda E. Cater, MS, RD, LDN is featured as an expert in the PMOS Diet materials from Johns Hopkins Medicine. Additional context comes from articles such as those by Dr. Thais Aliabadi on the metabolic focus of the name change.
