GLP-1 weight-loss drugs linked to higher rates of nail problems

People taking GLP-1 medications report nail detachment and discoloration at significantly higher rates than non-users.

Research presented at the European Academy of Dermatology and Venereology Congress found that people taking GLP-1 medications for obesity or diabetes experience nail disorders at significantly higher rates than those not taking the drugs. The study evaluated 575 GLP-1 users and 1,329 non-users with type 2 diabetes, obesity or both, recruited across France, the United States, Brazil and Mexico.

Among GLP-1 users, 39% reported nail detachment — where the nail separates from the nail bed — compared with 9% of non-users. Nail discoloration affected 46% of medication users versus 17% of controls. Overall, two-thirds of GLP-1 users reported experiencing at least one nail disorder, compared with 53% of the control group.

Researchers found that weight loss alone did not account for the difference. Even when adjusting for weight loss, existing dermatological conditions and nutritional deficiencies, nail detachment and discoloration remained two to three times more frequent among GLP-1 users. Dr Charles Taïeb, study author and clinical dermatologist at Necker University Hospital in Paris, stated that nail changes associated with GLP-1 therapies had 'essentially been anecdotal' until now. The New York Post reports that researchers noted they cannot say definitively whether the medication itself or its effects, such as nutritional deficiencies from reduced eating, cause the problems.
