Hormonal

Tirzepatide, a dual GIP/GLP-1 receptor agonist administered as a once-weekly injection, produces significantly greater weight loss and glycemic control in adults with obesity and type 2 diabetes compared to placebo, semaglutide, and long-acting insulin analogs.

If you have obesity and Type 2 Diabetes, standard diet and exercise may not be enough to control your blood sugar or achieve significant weight loss. Tirzepatide is a once-weekly injection that targets both GLP-1 and GIP hormones to improve insulin response, reduce appetite, and slow digestion. Clinical data shows it leads to greater weight loss than placebo, semaglutide, and insulin analogs. However, it carries risks of gastrointestinal side effects (nausea, vomiting) and is contraindicated for those with a history of medullary thyroid cancer. Consult a doctor to see if this high-efficacy intervention is appropriate for your specific health profile.

GoodSupportsHIGH confidence
Tirzepatide is a dual incretin agonist... Tirzepatide engages with the GIP receptor more than the GLP-1 receptor... In five clinical studies... patients randomized to receive the recommended dose of tirzepatide (15 mg) had their hemoglobin A1c level lowered by 1.6% more than placebo... The average weight reduction with tirzepatide was 15 pounds greater than placebo... 12 pounds greater than with semaglutide, 29 pounds greater than with insulin degludec, and 27 pounds greater than with insulin glargine.

Why this rating

Based on multiple clinical studies and a NEJM trial, though the authors note methodological limitations (commitment bias, lack of diversity) in the NEJM study.
