Overview of Tirzepatide, Orlistat, and Phentermine

1. Tirzepatide

Tirzepatide is a new injectable drug for weight loss and diabetes. It copies two hormones, GLP-1 and GIP. These hormones lower blood sugar and cut hunger. Studies show it can cause up to 20% weight loss. It is important to note that the effect of tirzepatide on weight loss is still under obeservation and have not approved by SAHPRA.

2. What is Orlistat?

Orlistat is a common medicine used for weight loss. It is sold under brand names like Xenical. The drug works by blocking an enzyme called lipase in the stomach. This stops much of the fat you eat from being broken down. As a result, your body absorbs less fat and fewer calories.

3. What is Phentermine?

Phentermine is an appetite suppressant that helps reduce hunger and calorie intake.

Phentermine, often combined with other treatments, is a short-term solution for weight loss. It works by stimulating the central nervous system to suppress appetite, making it easier to stick to a calorie-controlled diet.

While effective, Phentermine is usually recommended for individuals with no underlying health conditions and who need immediate weight management support.
