What Are GLP-1 Weight Loss Injections? (Saxenda, Ozempic, Wegovy, and Mounjaro)

GLP-1 weight loss injections are medical treatments designed to assist with weight loss by mimicking the effects of a hormone called glucagon-like peptide-1 (GLP-1). These medications help regulate appetite, control blood sugar levels, and slow digestion. GLP-1 injections are used in Singapore for individuals struggling with weight management despite following a healthy diet and exercise routine.

By targeting the body's appetite control mechanisms, GLP-1 injections work to:

• Slow stomach emptying, which helps reduce hunger.
• Promote fullness, leading to lower calorie intake.
• Regulate blood sugar levels, supporting overall health.

These characteristics make GLP-1 injections an effective option for sustainable weight management.

2. Ozempic (Semaglutide)

• A weekly injection containing semaglutide, originally developed for managing type 2 diabetes.

How Do GLP-1 Weight Loss Injections Work? (Saxenda, Ozempic, Wegovy, and Mounjaro)

GLP-1 weight loss injections work by mimicking the effects of glucagon-like peptide-1 (GLP-1), a hormone that naturally occurs in the body. This hormone plays a critical role in regulating appetite, controlling blood sugar levels, and supporting digestion. By enhancing these natural processes, GLP-1 injections help individuals achieve sustainable weight loss.

Here’s a detailed look at how GLP-1 injections promote weight loss:

1. Reducing Hunger

GLP-1 injections influence the brain's appetite control center, helping individuals feel less hungry. This reduction in appetite makes it easier to consume fewer calories throughout the day.

2. Slowing Digestion

These injections slow the emptying of the stomach, which prolongs the feeling of fullness after eating. This mechanism helps prevent overeating and supports better portion control.

3. Regulating Blood Sugar Levels

GLP-1 injections help stabilize blood sugar levels by improving insulin sensitivity and reducing glucose production. Stable blood sugar levels can decrease cravings, particularly for sugary and high-calorie foods.

4. Supporting Long-Term Weight Loss

By addressing the root causes of overeating and poor appetite control, GLP-1 injections provide a foundation for gradual and sustainable weight loss. They are most effective when combined with healthy lifestyle changes, including a balanced diet and regular physical activity.

Examples of GLP-1 Weight Loss Injections:

• Saxenda: Administered daily to help control appetite and reduce calorie intake.
• Ozempic and Wegovy: Weekly injections designed for convenient and effective weight management.
• Mounjaro: A newer option combining GLP-1 and GIP receptor agonists for enhanced results.

GLP-1 injections are typically prescribed for individuals with a BMI of 27 or higher with weight-related conditions or BMI of 30 and above. Consulting a doctor in Singapore can help determine the most suitable option for your needs.
