Summary

This study looked at how safe and effective weekly weight loss injections (like Mounjaro) are for adults with Bardet-Biedl Syndrome (BBS), a rare genetic condition that often causes severe obesity. Researchers compared weight changes in 300 patients who took the medication versus those who did not. The goal was to see if these injections can help manage weight long-term in people with BBS.
