GLP-1 use associated with nail detachment, hair loss
Healio reports on a congress presentation of an observational study comparing 575 GLP-1 receptor agonist users with 1,329 non-users, all with type 2 diabetes and/or obesity. Users reported more nail disorders and hair loss, including nail detachment (39.3% vs. 8.7%) and new-onset hair loss (26.1% vs. 11.6%). Researchers say the design cannot establish that the drugs caused the changes; a prospective study is planned.
Why it matters: Relevant to adults with type 2 diabetes or obesity who use or are considering GLP-1 medicines, and to the clinicians and dermatologists involved in their care.
