How does Wegovy work?

The active substance in Wegovy, semaglutide, is a ‘GLP-1 receptor agonist’.

It acts in the same way as GLP-1 (a natural hormone in the body) and, among other things, appears to regulate appetite by increasing a person’s feelings of fullness, while reducing their food intake, hunger and cravings.
