Hormonal

Tirzepatide, a dual GIP/GLP-1 receptor agonist administered once weekly, produces clinically meaningful weight loss (average 15-25% over 88 weeks) superior to placebo and semaglutide in adults with obesity or overweight.

If you have obesity or overweight with related health issues, Tirzepatide is an FDA-approved, once-weekly injection that works by mimicking gut hormones to reduce appetite and improve metabolism. Clinical trials show it leads to significant weight loss (up to 25% over nearly 2 years), often more than other popular drugs like semaglutide. It requires a calorie-restricted diet and exercise. Common side effects are gastrointestinal (nausea/diarrhea), but serious risks are rare. It is contraindicated for those with a history of medullary thyroid cancer.

GoodSupportsHIGH confidence
Tirzepatide induced a weight loss of 25.3% from week 0 to week 88, compared to 9.9% for the placebo group... At all doses, Tirzepatide was both noninferior and superior and cause more significant reductions in body weight as compared to semaglutide
