What are GLP-1 drugs?

---

GLP-1 drugs, or glucagon-like peptide-1 receptor agonists, are a class of medications increasingly used to treat obesity. These drugs are gaining attention due to their effectiveness in promoting significant weight loss and improving related health conditions.

How GLP-1 works to support weight loss

GLP-1 is a hormone produced in the gut with several functions that contribute to weight loss.

• Slowing gastric emptying. GLP-1 slows down the rate at which the stomach empties its contents into the small intestine. This prolongs the feeling of fullness after meals, helping to reduce overall food intake.
• Reducing appetite. It acts on the brain to decrease hunger, leading to lower food consumption.
• Enhancing satiety signals. GLP-1 enhances the body's natural signals of satiety, making it easier to stick to a reduced-calorie diet.

Common GLP-1 drugs

Several GLP-1 receptor agonists are approved specifically for weight management:

• Liraglutide (Saxenda). Injected once daily, Saxenda has been shown to help people lose and maintain weight when used alongside a reduced-calorie diet and increased physical activity.
• Semaglutide (Wegovy). Administered once weekly, Wegovy has demonstrated significant weight loss results in clinical trials and is a popular choice for managing obesity.
• Tirzepatide (Zepbound). Tirzepatide is a newer medication that acts on both GLP-1 and GIP (glucose-dependent insulinotropic polypeptide) receptors. It is administered once weekly and has shown impressive weight loss outcomes in clinical studies, making it a promising option for obesity treatment.

Benefits of GLP-1 drugs for obesity

• Improved health metrics. Weight loss achieved with GLP-1 drugs can improve various health metrics, such as blood pressure, cholesterol levels, and blood sugar control, reducing the risk of chronic diseases.
• Significant weight loss. Clinical studies have shown that GLP-1 drugs can lead to substantial weight loss, making them a valuable tool in obesity treatment.
• Sustained weight loss. These drugs help patients maintain their weight loss over time, which is crucial for long-term health benefits.

Possible Side Effects

While GLP-1 drugs are effective, they can have side effects. Common ones include:

• Nausea
• Vomiting
• Diarrhea
• Decreased appetite

These side effects often decrease as the body adjusts to the medication. It is important to discuss any concerns with a healthcare provider, as rare but serious side effects like pancreatitis can occur.

So...

GLP-1 drugs, including newer options like tirzepatide, are a promising option for treating obesity, offering significant and sustained weight loss benefits. By slowing gastric emptying, reducing appetite, and enhancing satiety, these medications help patients achieve and maintain a healthier weight. As with any medication, it's crucial to use GLP-1 drugs under the guidance of a healthcare provider to manage side effects and achieve the best results.
