Semaglutide belongs to a class of drugs called GLP-1 receptor agonists. It was approved by the FDA in 2017 as a once weekly injection to aid with weight loss. It mimics the action of a natural hormone GLP-1 which is released from intestinal cells in response to eating. It functions to regulate blood sugar levels, slows gastric emptying, and reduces appetite. Clinical trials have demonstrated significant weight loss in individuals using semaglutide, making it a promising option for those struggling with unintentional weight gain. It's important to note that the use of semaglutide for weight loss should be under the guidance of a healthcare professional. Individuals considering this treatment should discuss potential risks and benefits with their healthcare provider.
