Semaglutide is a medication primarily used to treat type 2 diabetes and obesity. It belongs to a class of drugs called GLP-1 receptor agonists (glucagon-like peptide-1 receptor agonists). It works by mimicking the action of the naturally occurring GLP-1 hormone, which helps regulate blood sugar levels and appetite.
Key effects of semaglutide include:
- Increasing insulin secretion when blood sugar levels are elevated
- Suppressing glucagon release, which helps reduce glucose production by the liver
- Slowing gastric emptying, leading to a longer feeling of fullness and reducing appetite
