GLP-1 medications & weight loss (overview)
GLP-1 receptor agonists are prescription drugs that mimic incretin hormones. They were developed for type 2 diabetes and, where approved, may also support weight management by reducing appetite and food intake. Examples discussed in public sources include semaglutide and dual GIP/GLP-1 agents such as tirzepatide; names and indications differ by country.
