Polycystic ovary syndrome (PCOS) affects up to five million people in the U.S., yet it remains poorly understood. Many people with PCOS go undiagnosed while experiencing symptoms such as irregular periods, changes in hair and body shape, acne and infertility. Even after a diagnosis, they’re often told to lose weight to manage symptoms—advice that some researchers now say can be harmful. 

A recent study found that people with PCOS are more likely to have eating disorders, regardless of their body mass index. Laura Cooney, an associate professor at the University of Wisconsin School of Medicine and Public Health, co-authored the study. She joins host Rachel Feltman to discuss why the focus on weight loss for PCOS treatment needs to be reconsidered.
