How Obesity Medications Work

Obesity is a complex condition that requires a multifaceted approach to treatment. While lifestyle changes remain the gold standard for managing obesity, medications can play a crucial role in supporting weight loss efforts.

Medications for Obesity: Alternatives to Lifestyle Changes

• Orlistat (first-line medication): Orlistat works by inhibiting pancreatic lipase, an enzyme that breaks down fat in the gut. By reducing fat absorption, Orlistat helps reduce weight gain and promote weight loss.

• Phentermine-topiramate (second-line medication): This combination medication works as a central nervous system stimulant to suppress appetite, while topiramate also has a mild effect on satiety. Together, they help reduce hunger and increase feelings of fullness.

Bariatric Surgery: A Last Resort for Severe Obesity

Bariatric surgery is typically reserved for individuals with severe obesity (BMI ≥ 40) or those with a BMI ≥ 35 who have at least one comorbidity, such as type 2 diabetes. Surgical interventions can lead to significant weight loss and improvement in associated health conditions.
