How Does Semaglutide Work?
Curious about how semaglutide works? Learn how this GLP-1 medication supports appetite regulation and metabolic health.
Thinking about semaglutide for weight loss? Learn what to expect, how it works, and what to ask a licensed provider before starting.
Interest in semaglutide has surged in recent years, especially for its potential role in weight management. Approved initially to help regulate blood sugar in people with type 2 diabetes, specific formulations of semaglutide are now FDA-approved for chronic weight management in adults with a qualifying body mass index (BMI).
However, before considering a consultation with a licensed provider, it's important to understand how semaglutide works, what clinical research has shown, and the key questions to ask to make a fully informed decision.
Let’s take a closer look at what you need to know first.
Semaglutide belongs to a class of medications known as GLP-1 receptor agonists. These drugs mimic the effects of glucagon-like peptide-1, a naturally occurring hormone involved in appetite regulation, insulin release, and blood sugar control.
In people with elevated BMI and related conditions, semaglutide may support:
A 2022 clinical trial evaluating 2.4 mg of semaglutide found that participants reported reduced appetite and lower energy intake, factors that may contribute to weight loss when paired with lifestyle changes.
The GLP-1 formulation used in this study is the same as the one later approved and marketed under the brand name Wegovy®.

Yes, but only specific formulations. Semaglutide 2.4 mg, marketed under the name Wegovy®, is FDA-approved for chronic weight management in adults with:
It is not approved as a general-use weight loss drug for cosmetic purposes or for individuals without qualifying medical criteria.
Eden helps individuals connect with independent, licensed healthcare providers who evaluate these factors and determine whether semaglutide is medically appropriate. Eligibility is not guaranteed.
Several clinical trials, particularly the STEP series of studies, have demonstrated that semaglutide 2.4 mg, when paired with diet and physical activity, may lead to weight loss in eligible adults.
One pivotal study published in the New England Journal of Medicine found:
These results occurred alongside healthy lifestyle changes and under clinical supervision.

Eligibility is determined by a licensed healthcare provider and generally depends on:
Eden enables you to discuss these factors in detail with a licensed provider, who will determine whether semaglutide is a safe and appropriate option for you.
As with any prescription medication, semaglutide may cause side effects. Based on clinical trial data*, the most common include:
Generally, side effects occur early in treatment and tend to subside as the body adjusts to the medication. In rare cases, more serious events like pancreatitis, gallbladder issues, or allergic reactions have been reported.
You should always discuss these risks with a licensed provider in advance. They can recommend a gradual dose-escalation strategy to help minimize discomfort.
*The study included semaglutide (branded as Ozempic® and Wegovy®), liraglutide (Saxenda®), exenatide (Byetta® and Bydureon®), dulaglutide (Trulicity®), and albiglutide (formerly Tanzeum®). Side effects listed were observed across multiple GLP-1 receptor agonists, including semaglutide (Ozempic®, Wegovy®), liraglutide (Saxenda®), and others in the class. Individual experiences may vary based on formulation and dosage.
