Medical weight management has evolved with the development of medications that influence appetite and metabolic regulation.
Semaglutide is a glucagon-like peptide-1 receptor agonist that has demonstrated meaningful weight-loss benefits in clinical trials when prescribed to appropriate patients.
What Is Semaglutide?
Semaglutide mimics the activity of GLP-1, a hormone involved in appetite regulation, glucose control, and gastric emptying.
By activating GLP-1 receptors, semaglutide can reduce hunger and increase feelings of fullness.
Different semaglutide products have different FDA-approved indications and dosing schedules.
Who May Qualify for Medical Weight Loss?
Weight-management medications are generally considered for adults meeting applicable BMI criteria, often a BMI of 30 or greater, or 27 or greater with a weight-related medical condition.
Eligibility depends on the specific medication, medical history, and clinical assessment.
What Results Can Patients Expect?
In the STEP 1 clinical trial, adults with overweight or obesity who did not have diabetes achieved an average weight reduction of approximately 14.9% after 68 weeks with semaglutide 2.4 mg plus lifestyle intervention, compared with approximately 2.4% with placebo.
Individual results vary, and not everyone achieves the study average.
Common Side Effects and Risks
Nausea, vomiting, diarrhea, constipation, and abdominal discomfort are common.
More serious concerns include pancreatitis, gallbladder disease, dehydration-related kidney injury, and other complications.
Certain semaglutide products carry a boxed warning concerning thyroid C-cell tumors observed in rodents and are contraindicated in patients with a personal or family history of medullary thyroid carcinoma or MEN2.
Long-Term Weight Management
Successful treatment includes adequate nutrition, physical activity, resistance exercise, and ongoing medical follow-up.
Weight regain may occur after discontinuation, making long-term planning important.
Frequently Asked Questions About Semaglutide

Can semaglutide cause muscle loss?
Weight loss can include lean tissue loss, making resistance training and adequate protein intake important.
Is semaglutide appropriate during pregnancy?
No. Weight-management semaglutide should not be used during pregnancy, and product-specific discontinuation guidance applies before planned pregnancy.
