What are GLP-1 medications?
GLP-1 medications are a class of prescription treatments that mimic a naturally occurring hormone in the body called glucagon-like peptide-1 (GLP-1).
This hormone plays an important role in regulating appetite, digestion, and blood sugar levels. GLP-1 medications work by enhancing these natural processes, helping people feel fuller for longer and making it easier to reduce calorie intake.
Many modern weight management programs use GLP-1 medications as part of a clinically guided treatment plan supervised by licensed healthcare professionals.
How they work
in your body
GLP-1 medications support weight management through three key mechanisms working together.
Appetite regulation
GLP-1 medications act on appetite centers in the brain to help reduce hunger signals. Many patients report feeling satisfied with smaller portions and experiencing fewer cravings throughout the day.
Slower digestion
These medications slow the rate at which food leaves the stomach. This helps you feel fuller for longer after meals, which can naturally reduce overall calorie consumption.
Blood sugar control
GLP-1 medications also help regulate blood sugar by supporting insulin release when needed, and reducing excess glucose production. This is one reason they were originally developed for people with type 2 diabetes.
Together, these effects can make it significantly easier for many people to maintain a calorie deficit and achieve sustainable weight loss.
How effective are
GLP-1 treatments?
Branded GLP-1 medications such as Wegovy®, Zepbound®, Ozempic®, Mounjaro®, and Saxenda® are FDA-approved and have been extensively studied for their approved uses.
In the SURMOUNT-1 trial, adults with obesity on 15mg of Tirzepatide lost an average of 22.5% body weight at 72 weeks.
22.5%
Clinical studies and real-world treatment programs have shown that branded, FDA-approved GLP-1 medications such as Zepbound and Wegovy can be highly effective for chronic weight management when combined with medical supervision and healthy lifestyle habits.
Many patients using these GLP-1 treatments in structured programs experience meaningful weight loss over time. Treatment plans are designed to support gradual, sustainable progress rather than rapid short-term changes.
Licensed healthcare providers usually monitor treatment progress and adjust dosing where appropriate to help maximize results while maintaining safety.
Are GLP-1 medications safe?
Branded GLP-1 medications have been studied extensively and are approved by the FDA for treating type 2 diabetes and chronic weight management.
Well-established safety profile
When prescribed by qualified healthcare professionals and used according to medical guidance, these medications have a well-established safety profile backed by years of clinical research.
Common side effects
Like any prescription treatment, GLP-1 medications may cause side effects. The most common are typically mild and may include nausea, digestive discomfort, or temporary changes in appetite. Providers monitor patients to help manage any side effects.
Consultation required
GLP-1 treatments are not suitable for everyone, which is why a medical consultation is always required before starting therapy. Your provider will assess eligibility and monitor your progress.

What you
need to know
Ozempic is FDA-approved for type 2 diabetes. Wegovy is FDA-approved for chronic weight management. They use the same active ingredient (semaglutide) at different doses. Switching between them is a medical decision your prescriber will make based on your indication, not a choice to make on your own.
Wegovy is FDA-approved specifically for chronic weight management, while Ozempic is approved for type 2 diabetes. Pricing differences reflect their approved uses, insurance coverage variations, and how each is positioned in the market.
The core side effects that some people experience with GLP-1 medications — nausea, digestive discomfort, and changes in appetite — are similar across most options — see our breakdown of side effects here. Individual experiences vary, and your provider can help you manage any side effects that arise.
Yes, all GLP-1 medications — including Ozempic, Wegovy, Mounjaro, and Zepbound — require a prescription from a licensed healthcare provider. A consultation is required to assess whether treatment is appropriate for you.
Compounded Semaglutide is prepared by licensed compounding pharmacies. The FDA declared the semaglutide shortage resolved in February 2025, which significantly narrowed the legal basis on which 503A pharmacies may compound essentially-copies of semaglutide. The FDA has also stated that semaglutide salt forms (e.g., semaglutide sodium) are unapproved new drugs and should not be marketed as substitutes for FDA-approved semaglutide. Regulatory status, oversight, and safety review differ from brand-name medications such as Wegovy (FDA-approved for chronic weight management) and Ozempic (FDA-approved for type 2 diabetes). Discuss the specifics with a licensed provider before starting.
