What is semaglutide?
Semaglutide copies GLP-1, the fullness hormone your gut releases after eating — slowing digestion, quieting appetite, and steadying blood sugar. It's one of the most-studied molecules in modern metabolic medicine.

If you're starting from zero, begin with the mechanism article — the rest makes more sense once the hormone story is clear.
