Tirzepatide produces significant weight loss (mean 18.73%) and improves quality of life in overweight or obese adults without diabetes, but significantly increases the risk of adverse events compared to placebo.

Tirzepatide is a highly effective treatment for weight loss in non-diabetic overweight or obese adults, producing an average 18.73% body weight loss. However, it comes with a significantly higher risk of adverse events, particularly gastrointestinal issues, compared to placebo. Patients should be monitored closely for these side effects.
