Overview Medication Comparison Table Best GLP-1 Medications Best Oral Weight Loss Pills Side Effects Comparison Cost Comparison FAQWeight Loss Medication Overview
Modern weight loss medications work through several different mechanisms, including appetite suppression, blood sugar regulation, delayed stomach emptying, and reduced fat absorption.
Some medications were originally developed for diabetes management, while others were designed specifically for obesity treatment. The best option depends on weight loss goals, medical history, budget, and tolerance to side effects.
In recent years, GLP-1 receptor agonists such as Ozempic and Wegovy have become increasingly popular due to their strong weight loss results. However, traditional medications like Orlistat, Xenical, and Topiramate remain widely used because of their lower cost and different mechanisms.

| Ozempic | GLP-1 Injection | 10–15% | Strong appetite suppression | High |
| Wegovy | GLP-1 Injection | 15%+ | Obesity treatment | High |
