WHO GLP-1 Obesity Treatment Guideline: JAMA Special Communication Continues to Shape Global Coverage Strategy
WHO's December 2025 first-ever GLP-1 guideline for obesity treatment in adults — published as a JAMA Special Communication and updated through Q1 2026 — continues to influence national and payer policy. WHO issued conditional recommendations for chronic GLP-1 therapy as part of comprehensive obesity management, while flagging cost, long-term safety, health-system preparedness, and equity implications. The framework directly informs the political economy of the U.S. Medicare Bridge program extension to 2027 and similar coverage debates globally.
