FAQ
What is a GLP-1 medication?
GLP-1 medications are a class of drugs that mimic a naturally occurring hormone in your body called glucagon-like peptide-1. They help regulate blood sugar, slow digestion, and reduce appetite. Semaglutide, sold under brand names like Ozempic and Wegovy, is one of the most well-known medications in this class.
Is Ozempic the same as Wegovy?
Both Ozempic and Wegovy contain the same active ingredient, semaglutide, but they are approved for different purposes. Ozempic is FDA-approved for type 2 diabetes management, while Wegovy is FDA-approved specifically for chronic weight management. The dosing ranges also differ between the two formulations.
How does semaglutide help with weight loss?
Semaglutide works by activating GLP-1 receptors in the brain that regulate hunger and satiety, which helps you feel full sooner and stay full longer. It also slows the rate at which your stomach empties food into your intestines. These combined effects typically lead to reduced calorie intake and meaningful weight loss over time.
Who is a good candidate for GLP-1 therapy?
GLP-1 therapy is generally considered for adults with obesity, defined as a BMI of 30 or greater, or for those with a BMI of 27 or greater who also have a weight-related health condition such as type 2 diabetes or high blood pressure. Your physician will review your full medical history before recommending this treatment. It is not appropriate for everyone, so a thorough clinical evaluation is essential.
How much weight can I expect to lose on semaglutide?
Clinical trials have shown that people using semaglutide for weight management can lose an average of 15 percent or more of their body weight over approximately 68 weeks. Individual results vary depending on diet, physical activity, starting weight, and adherence to the medication. GLP-1 therapy works best as part of a comprehensive lifestyle program.
What are the most common side effects of GLP-1 medications?
The most frequently reported side effects include nausea, vomiting, diarrhea, and constipation, particularly when starting the medication or increasing the dose. These gastrointestinal symptoms are usually temporary and tend to improve as your body adjusts. Your physician can recommend strategies to minimize discomfort during the early weeks of treatment.
Will I need to take a GLP-1 medication forever?
Research shows that weight typically returns when GLP-1 medications are discontinued, which suggests that ongoing treatment may be necessary for sustained results in many patients. Obesity is recognized as a chronic condition, much like hypertension or diabetes, and long-term management is often required. Your physician will help you evaluate the benefits and risks of continued use over time.
Can GLP-1 medications be used if I do not have diabetes?
Yes, semaglutide in its Wegovy formulation is FDA-approved for chronic weight management in adults without diabetes. GLP-1 receptor agonists have demonstrated significant clinical benefits for metabolic health even in people with normal blood sugar levels. Your physician can determine whether this therapy is appropriate based on your individual health profile.
Are GLP-1 medications safe for the heart?
Large cardiovascular outcome trials have shown that semaglutide and other GLP-1 receptor agonists reduce the risk of major adverse cardiovascular events in high-risk patients. In fact, the FDA has approved semaglutide to reduce cardiovascular risk in adults with obesity or overweight who have established heart disease. This makes GLP-1 therapy particularly valuable for patients with overlapping metabolic and cardiovascular conditions.
How is semaglutide administered?
Semaglutide is most commonly given as a once-weekly subcutaneous injection using a prefilled pen device. An oral tablet formulation of semaglutide is also available for type 2 diabetes management, though the injectable form generally achieves higher drug exposure. Your physician will guide you on proper injection technique and help you choose the formulation best suited to your needs.
