Nail detachment over four times more common among GLP-1 users, first controlled study finds
Nail detachment is more than four times as common among people taking GLP-1 receptor agonists as among comparable people with obesity or type 2 diabetes who are not taking the drugs, according to the first controlled study to examine their potential effects on nail health.
A recent controlled study has revealed that people taking GLP-1 receptor agonists are over four times more likely to experience nail detachment compared to those without these medications. Conducted across France, the United States, Brazil, and Mexico, the research involved 575 GLP-1 users and 1,329 controls. While 39% of GLP-1 users reported nail detachment, only 9% of controls experienced this condition.
Additionally, two-thirds of GLP-1 users (66%) had at least one nail disorder, versus 53% of controls. Nail discoloration was also more common among GLP-1 users (46%) than controls (17%). The researchers emphasize that these findings do not definitively prove the causality of GLP-1 receptor agonists in causing nail changes, as the study is cross-sectional and based on patient-reported symptoms.
However, the results suggest that weight loss alone does not fully explain the increased prevalence of nail problems in GLP-1 users.
