Understanding Semaglutide

Semaglutide: Origin, mechanism of action, and its primary use in diabetes management.

Semaglutide, a glucagon-like peptide-1 (GLP-1) receptor agonist, originates from the family of incretin mimetics. Initially developed for diabetes management, it emulates the functions of the natural GLP-1 hormone. This synthetic version enhances insulin secretion in response to elevated blood sugar levels, curbing excess glucose production by the liver. Its primary action slows stomach emptying, reducing appetite and promoting a feeling of fullness. Administered via weekly subcutaneous injections, semaglutide aids in glucose control, lowers A1C levels, and minimizes the risk of cardiovascular events in individuals with type 2 diabetes. Its efficacy extends beyond diabetes, showing significant promise in weight loss interventions.
