Although GLP-1 medication like Ozempic, Wegovy, and Zepbound are lauded for his or her transformative results, together with weight reduction and decrease blood sugar, they’re not without their side effects. These can embrace nausea, bone density loss, and digestive troubles—and in keeping with a brand new examine, one other bodily change could also be becoming a member of that record.
Researchers on the College of Pennsylvania in contrast sufferers taking GLP-1s to deal with their Sort 2 diabetes with these utilizing different remedy choices and located a hair-raising connection: Taking GLP-1s correlated with the next probability of hair loss in comparison with taking different medication.
Linking GLP-1s and alopecia
This examine, published this week in The BMJ, isn’t the primary to recommend that GLP-1s and hair loss may go hand in hand. In 2023, the FDA required that GLP-1s together with Ozempic and Wegovy record alopecia as a possible hostile impact.
However since then, little analysis has been performed into the connection between GLP-1s and hair loss. That’s why the researchers determined to dig deeper, inspecting 12,000 Sort 2 diabetes sufferers who have been prescribed GLP-1s between 2019 and 2024.
“Though hair loss doesn’t sometimes end in bodily hurt, it could have vital psychosocial penalties, affecting vanity, high quality of life, and adherence to remedy,” the researchers wrote of the significance of their analysis.
In comparison with the same pattern dimension of Sort 2 diabetes sufferers taking different medication for remedy, GLP-1s customers have been considerably extra prone to expertise hair loss inside a median of two to a few years after beginning remedy.
GLP-1 customers have been 37% extra prone to develop alopecia than diabetes sufferers taking SGLT-2 inhibitors, one other widespread drug class for remedy. Hair loss was additionally 68% extra possible amongst GLP-1 customers than amongst sufferers on DPP-4 inhibitors, a 3rd customary class of diabetes remedy medication.

These numbers could sound alarming, however the danger of growing alopecia after beginning GLP-1s continues to be extraordinarily low. Of these 12,000 sufferers taking GLP-1s, solely roughly 200 developed alopecia, or round 1.6%. Moreover, whereas the examine proves a correlation between hair loss and GLP-1 use, it doesn’t affirm causation.
Even for GLP-1 customers who did expertise hair loss, the researchers famous that they primarily developed non-scarring alopecia, a model of the situation that enables for hair regrowth beneath the proper situations.
“Though absolutely the danger was small, consciousness of this potential impact could help knowledgeable, affected person centred remedy choices,” the examine’s authors wrote of their conclusion. “Additional research are wanted to make clear underlying mechanisms, assess scientific severity and reversibility, and establish sufferers who could also be at larger danger.”
