GLP-1 receptor agonists like semaglutide and tirzepatide have transformed medical weight loss. Here's how they work, who they're for, and what to expect.
Medical weight loss has been transformed in recent years by the emergence of GLP-1 receptor agonist medications. Originally developed for type 2 diabetes management, these medications have demonstrated significant effectiveness for weight loss in adults with obesity or weight-related health conditions.
If you have struggled with weight despite diet and exercise efforts, understanding how these medications work — and whether they may be appropriate for you — is worth discussing with a qualified healthcare provider.
GLP-1 receptor agonists are a class of medications that mimic a naturally occurring hormone called glucagon-like peptide-1. This hormone plays a role in regulating blood sugar levels, hunger, and digestion. By activating GLP-1 receptors, these medications can:
Common GLP-1 medications approved for weight management include semaglutide (brand names Ozempic and Wegovy) and tirzepatide (Mounjaro and Zepbound).
These medications are typically considered for adults who meet certain criteria. Evaluation by a medical provider is essential to determine candidacy. General considerations include:
Certain medical conditions and medications may be contraindications. A thorough medical evaluation is always required before starting treatment.
GLP-1 medications are typically administered as once-weekly injections. They are most effective when combined with lifestyle modifications including dietary changes and increased physical activity. Side effects — most commonly mild nausea — often improve as the body adjusts over several weeks.
Weight loss with GLP-1 medications tends to be gradual and sustained. Clinical trials have demonstrated average weight reductions of 15–20% of body weight in many patients over 12–18 months.
