A multinational controlled study presented at the EADV Congress 2026 found that GLP-1 weight loss and diabetes drugs (Ozempic, Wegovy, Mounjaro, Zepbound) are associated with a significantly higher rate of nail detachment and discoloration, with weight loss alone not fully explaining the effect.
European researchers found that GLP-1 users are significantly more likely to develop hair loss and nail problems, particularly nail detachment, compared to non-users, adding to known risks of semaglutide and tirzepatide.
The article discusses a potential breakthrough in neuroscience that could lead to transformative brain treatments, drawing parallels to the significant impact of Ozempic on weight loss.
A study from Southeast University found that GLP-1 drugs like Ozempic reverse depression-like behavior in mice by promoting growth of Lactobacillus delbrueckii, which produces endocannabinoids that reduce stress effects.
