Question 1

How does Wegovy work?

Accepted Answer

Wegovy (semaglutide) is a GLP-1 receptor agonist that mimics a natural gut hormone to regulate your blood sugar levels and suppress your appetite.

It works by:

Reducing appetite, making you feel less hungry.
Reducing cravings, helping you make healthier choices.
Lowering your ‘set point’, allowing for more weight loss before you reach a plateau.

Wegovy is most effective when combined with healthy lifestyle changes, including a balanced diet and regular exercise.
