Wegovy Side Effects: What Indian Patients Need to Know

Wegovy (semaglutide) is a prescription medication increasingly used for weight management and to improve blood sugar control in adults with type 2 diabetes. While it can be an effective tool, like all medications, it comes with potential side effects. This guide aims to provide comprehensive information about the side effects of Wegovy, specifically tailored for patients in India, covering common, serious, and long-term effects, as well as management strategies. Understanding Wegovy and Its Mechanism Wegovy belongs to a class of drugs called glucagon-like peptide-1 (GLP-1) receptor agonists. It works by mimicking the action of the natural GLP-1 hormone, which helps to: Regulate appetite by signaling to the brain that you are full. Slow down the emptying of your stomach, further contributing to feelings of fullness. Improve blood sugar control by increasing insulin secretion and decreasing glucagon secretion. This dual action makes it beneficial for both weight loss and managing type 2 diabetes. However, these mechanisms also contribute to some of its common side effects.
