Introduction
If you are experiencing nausea on Mounjaro, this is one of the most commonly reported side effects of GLP-1 weight loss injections.
Mounjaro (tirzepatide) works by slowing digestion and affecting appetite hormones. While this helps control hunger, it can also lead to temporary feelings of sickness, especially in the early stages of treatment.
Most cases are mild and improve as your body adjusts.
