For weight loss, your clinician will likely look at your BMI (body mass index)a rough estimate of your body composition based on your height and weight
The primary mechanisms of action include: Enhancing insulin secretion from pancreatic beta cells in a glucose-dependent manner, meaning insulin is only released when blood glucose levels are elevated Suppressing glucagon release from pancreatic alpha cells, which reduces hepatic glucose production Slowing gastric emptying , which helps moderate post-meal blood glucose spikes Reducing appetite through central nervous system effects, leading to decreased caloric intake and weight loss Examples of GLP-1 receptor agonists available in the UK include exenatide (Byetta, Bydureon), liraglutide (Victoza for diabetes, Saxenda for weight management), dulaglutide (Trulicity), lixisenatide (Lyxumia), and semaglutide (Ozempic/Rybelsus for diabetes, Wegovy for weight management)
