Wegovy: A Revolutionary Weight Management Treatment? A Closer Look
Wegovy, approved by the US FDA in April 2023, is a novel weight management medication. Its active ingredient, semaglutide, is a glucagon-like peptide-1 (GLP-1) receptor agonist. Administered as an injection once a week, Wegovy works primarily through the following mechanisms:
- Appetite Suppression: Reduces appetite by acting on the hypothalamus, the brain's appetite control center.
- Increased Satiety: Promotes feelings of fullness by acting on the stomach.
- Improved Blood Sugar Control: Mimics the action of GLP-1, a blood sugar-regulating hormone, to enhance blood sugar control.
Efficacy of Wegovy:
Clinical trials have demonstrated Wegovy's effectiveness in:
- Weight Loss: Achieved an average weight loss of over 15% compared to a placebo.
- Blood Sugar Control Improvement: Lowered HbA1c levels by 1% or more in patients with diabetes.
- Cardiovascular Health Improvement: Reduced LDL cholesterol levels and blood pressure.
Side Effects of Wegovy:
Common side effects of Wegovy include:
- Nausea
- Vomiting
- Diarrhea
