Overview of Prescription Weight Loss Pills

Prescription weight loss pills are medications that help people lose weight by suppressing appetite, increasing metabolism, or blocking the absorption of fat and carbohydrates. They can be prescribed by a doctor to treat obesity in adults with a body mass index (BMI) greater than 30 kg/m2.

Types of Prescription Weight Loss Pills:

There are several types of prescription weight loss pills available on the market today. These include Phentermine, Orlistat (Xenical), Liraglutide (Saxenda), Bupropion/Naltrexone (Contrave), and Lorcaserin (Belviq). Each type works differently and has different side effects associated with it.

How Do They Work?

Phentermine is an appetite suppressant that helps reduce hunger cravings while Orlistat blocks the absorption of dietary fats from food intake.

Liraglutide stimulates hormones in the brain to decrease hunger signals while Bupropion/Naltrexone helps control cravings for unhealthy foods like sugar and carbs.

Finally, Lorcaserin acts on serotonin receptors in the brain to increase feelings of fullness after eating smaller meals.

The primary benefit associated with prescription weight loss pills is their ability to help people achieve significant results when combined with diet and exercise changes over time.

However, there are potential risks involved as well such as increased heart rate, insomnia, dry mouth, constipation or diarrhea depending on which pill you take.
