JAMA Network Open 10.1001/jamanetworkopen.2026.4722March 31, 2026 at 11:00 AM EDT
What are the associations between glucagon-like peptide-1 receptor agonists (GLP-1 RAs) and noncardiometabolic outcomes, and how credible is the available evidence?In this umbrella review of 60 meta-analyses of 1751 randomized clinical trials involving approximately 3 million participants, the most consistent associations with GLP-1 RAs were increased gastrointestinal adverse events (including nausea and vomiting). Suggested protective associations were reported for serious infections and respiratory disease, while possible associations with pancreatitis and gallbladder or biliary disease remained exploratory.This review observed signals of an association between GLP-1 RAs and lower risks of respiratory disease and serious infections; however, the credibility of the evidence was limited and require further confirmation.
