What are the weight loss injections in the stomach once a week?

The weekly weight loss injections in the stomach refer to a class of medications known as GLP-1 receptor agonists. These drugs mimic the natural hormone GLP-1 (glucagon-like peptide-1), which helps regulate appetite, insulin secretion, and blood sugar levels. By activating GLP-1 receptors, these injections slow digestion, reduce hunger, and promote a feeling of fullness — leading to significant and sustainable weight loss in many patients.

Common examples include semaglutide (Ozempic, Wegovy) and liraglutide (Saxenda), which are administered once a week or daily, depending on formulation. Initially developed to treat type 2 diabetes, GLP-1 injections have also been approved for obesity management in non-diabetic patients. They are typically injected subcutaneously in the abdomen, thigh, or upper arm. When combined with diet and exercise, weekly GLP-1 injections provide one of the most effective modern treatments for weight control and metabolic improvement.
