Q. How exactly do popular weight loss drugs like Wegovy and Saxenda work? I'm curious about the mechanism behind the weight loss.
These drugs are GLP-1 analogues that mimic satiety hormones, signaling the brain to stop eating while slowing down gastric emptying. By artificially maintaining a feeling of fullness, they bolster appetite control where willpower alone might struggle. However, since they slow down digestive motility, side effects such as nausea and indigestion are common.
