Weight lost refers to the reduction in body weight that is typically achieved through lifestyle changes, medications, or bariatric surgeries like the RNY or gastric band. Weight loss, particularly significant or rapid weight loss, can have dramatic positive effects on a person's overall health, reducing the risk of heart disease, diabetes, and other obesity-related conditions. Successful weight loss usually requires long-term changes to diet, exercise, and behavior.

This medication is part of a broader initiative to provide patients with additional tools to combat the obesity epidemic. Wegovy is typically prescribed alongside lifestyle changes to maximize its effectiveness.
