WeGovy is an injectable treatment used for weight management and obesity. It is a type of drug called GLP-1 (glucagon-like peptide-1) receptor agonist, which works by mimicking the effects of a naturally occuring hormone in the body.

This hormone helps to regulate apetite and food intake by mimicking the effects of GLP-1. This reduces the feeling of hunger and increases the feeling of fullness.
