GLP-1 medications, also known as glucagon-like peptide-1 receptor agonists, are a type of injectable medication used for weight management in adults with obesity or overweight and weight-related health conditions. These medications work by mimicking a natural hormone in your body called glucagon-like peptide-1 (GLP-1). This hormone helps regulate appetite and blood sugar levels. When you take GLP-1 medication, it signals to your body that you're full, which can help you feel less hungry and eat less overall. By reducing hunger and potentially influencing other factors like how your body absorbs nutrients, GLP-1 medications can be a tool for weight loss and weight management.
