Respiratory Adverse Events of Weight-Loss Drugs: A Systematic Review and Meta-Analysis.

Zeng L, Zinmon-Htet C, Hundie T, et al. Annals of the American Thoracic Society. 2026.

Editor's note

A systematic review and meta-analysis of 123 studies assessing respiratory adverse events of weight-loss medications, including semaglutide and tirzepatide. The pooled randomized-trial data, judged at low risk of bias, showed no signal of increased respiratory harm versus placebo, though evidence specific to people with asthma was sparse. This is a reassuring, well-conducted synthesis on a focused safety question.

Plain-language abstract

This systematic review and meta-analysis of 123 studies found that semaglutide, tirzepatide, and liraglutide were not associated with increased respiratory adverse events compared with placebo. Common events like nasopharyngitis occurred but were not linked to the drugs specifically.
