GLP-1 Weight Loss Injections explained

GLP-1 medicines copy a gut hormone that signals fullness and helps control blood sugar. Several are used for chronic weight management in people with obesity, or overweight with a related health problem. They are medical treatments, not cosmetic shortcuts, and must be prescribed and monitored by a doctor.

How GLP-1 Weight Loss Injections works

The medicine is injected under the skin with a pen, either daily or weekly depending on the product. It slows stomach emptying and acts on the brain to reduce hunger, so people eat less. Semaglutide (Wegovy) and liraglutide (Saxenda) act on GLP-1, while tirzepatide (Mounjaro) acts on both GLP-1 and GIP. The doctor sets and adjusts the dose over time.
