Ozempic works through several complementary mechanisms: it stimulates insulin secretion from the pancreas when blood glucose levels are elevated, suppresses the release of glucagon (a hormone that raises blood sugar), slows gastric emptying to reduce post-meal glucose spikes, and acts on appetite centres in the brain to promote satiety
However, over half of patients experience mild and typically transient side effects, most commonly vomiting, nausea, constipation, and diarrhea
Peptide approaches aim for slower, self-regulated change
Ozempic promotes weight loss through several mechanisms: Appetite suppression: It signals fullness to the brain, reducing hunger and cravings Delayed gastric emptying: Food stays in the stomach longer, increasing satiety Lower calorie intake: Reduced hunger naturally leads to eating less Together, these effects make it easier to maintain a calorie deficit without constant hunger
