GLP-1 receptor agonists are the most consequential drug class to emerge in obesity and type-2 diabetes since metformin. The category started with exenatide and liraglutide, broke commercial ceilings with semaglutide (Ozempic, Wegovy) and tirzepatide (Mounjaro, Zepbound), and is now expanding into orals (orforglipron, oral semaglutide), triple agonists (retatrutide), and amylin combinations (cagrisema, eloralintide).
The signal worth tracking has shifted. Weight loss alone is no longer the headline — secondary indications are. SELECT showed a 20% drop in major adverse cardiovascular events for non-diabetic adults with obesity. A Mass General Brigham analysis in JAMA reported 42–58% lower heart-failure hospitalizations in HFpEF. AAN 2026 added migraine, dementia incidence, and Parkinson's signals to the growing list. The Phase 3 EVOKE Alzheimer's trial, by contrast, missed its endpoint.
Gallup's July 7, 2026 poll release documented the first large-population evidence that GLP-1 uptake is bending the US obesity curve: 11% of US adults now take a GLP-1 for weight loss (up from 3% in 2024 and 8% in 2025), and the US adult obesity rate has drifted from a 2022 peak of 39.9% down to 36.4% in 2026. Awareness climbed from 80% to 91% over the same span. Browse the latest below, or filter by drug at #semaglutide, #tirzepatide, #orforglipron, and #retatrutide.
Over 3,546 lawsuits are now consolidated in two federal MDLs — one for gastroparesis and one for NAION vision loss. On March 3, a federal judge appointed lead counsel for the NAION MDL. Studies show semaglutide users face a fourfold increase in NAION risk, with vision loss claims now generating more legal attention than earlier gastroparesis cases.
CMS confirmed that Medicare Part D beneficiaries will gain access to Wegovy and Zepbound for weight loss through the Medicare GLP-1 Bridge program starting July 2026 at a $50 monthly copayment, bridging to the full BALANCE Model launching in Medicare Part D in January 2027.
CNBC reports that within six months of starting a GLP-1 medication, households reduce grocery spending by 5.3% and fast-food spending by 8%. Dinner traffic has fallen 6% among regular users, with ultra-processed food spending down 10%. Food companies are racing to develop protein- and fiber-rich 'GLP-1 friendly' products.
A comprehensive NeurologyLive review examines evidence for repositioning GLP-1 drugs across neurological conditions. Exenatide and lixisenatide show motor benefits in Parkinson's disease, while GLP-1 agonists reduced intracranial pressure and migraine days in idiopathic intracranial hypertension. The semaglutide EVOKE trials in Alzheimer's failed clinically despite modest biomarker improvements.
