Whereas it’s not clear why semaglutide is linked to better hair loss than older weight-loss medicine, Sodhi says scientists have some theories.

Outcomes like this, and extra research on the longer phrases results of GLP-1 medicine, are necessary to serving to individuals stability the dangers and advantages of those medicines. “If individuals don’t know the potential negative effects,” says Sodhi, “then they could be entering into one thing they didn’t join.”
