Hormonal

GLP-1 receptor agonists (liraglutide, semaglutide, dulaglutide) produce significant weight loss in obese patients (BMI ≥30 or ≥27 with comorbidities) through mechanisms including delayed gastric emptying, increased satiety, and increased resting energy expenditure.

If you have obesity or overweight with related health issues, GLP-1 medications like liraglutide are a proven, effective treatment. They work by mimicking a hormone that signals fullness and increases energy use, not just by slowing digestion. You take a daily injection, but the significant weight loss and health improvements can be worth it. Always consult a doctor to see if you are a candidate, especially if you have a history of thyroid cancer.

GoodSupportsHIGH confidence
The weight loss associated with GLP-1R analogues is thought to be achieved through a variety of mechanisms, including delayed gastric emptying, increased satiety, and increased resting energy expenditure, as well as direct effects on the appetite center of the brain
