Atypical Anorexia Nervosa Developed in a Patient with Severe Obesity and Type 2 Diabetes Following Sleeve Gastrectomy and Postoperative Treatment with Semaglutide and Tirzepatide.

Saito C, Saito M, Nakagawa M, et al. Internal medicine (Tokyo, Japan). 2026.

Editor's note

A single case cannot establish causation, and this patient also underwent sleeve gastrectomy, making the peptides' specific contribution impossible to isolate. It is a useful safety-awareness signal that rapid weight loss regimens may coincide with disordered-eating psychopathology in susceptible individuals. Regard it as hypothesis-generating rather than as evidence of a defined risk.

Plain-language abstract

This single case report describes a 60-year-old woman who developed atypical anorexia nervosa after bariatric surgery combined with semaglutide and tirzepatide. The authors note the co-occurrence but cannot establish that the medications were the cause.
