1. Understanding Semaglutide

1.1 Mechanism of Action

Semaglutide is a GLP-1 receptor agonist that mimics the human glucagon-like peptide-1 hormone. This hormone regulates blood sugar by enhancing insulin secretion and reducing glucagon release. Additionally, it slows gastric emptying, leading to prolonged satiety and reduced caloric intake, a feature crucial for weight management.

GLP-1 receptor agonists like semaglutide influence the brain’s appetite control centers, which helps people consume fewer calories without feeling deprived. The compound’s dual ability to manage blood glucose and reduce hunger differentiates it from older medications that target only one of these aspects.

1.2 Approved Uses

• Type 2 Diabetes Management: Semaglutide lowers blood sugar effectively and supports long-term glycemic control.
• Chronic Weight Management: Marketed under the brand name Wegovy, semaglutide is approved for adults with obesity (BMI ≥ 30) or overweight individuals (BMI ≥ 27) with at least one weight-related health condition, such as hypertension or type 2 diabetes.

2. Current Usage Statistics
