How does tirzepatide work in the body?
Tirzepatide (sold as Mounjaro) helps with weight loss by mimicking two natural hormones—GIP and GLP-1—that help control blood sugar and appetite. It increases insulin when you eat, reduces the amount of sugar released by the liver, and makes you feel fuller for longer, so you eat less. This combined action leads to lower blood sugar and supports weight loss in people who are overweight or living with type 2 diabetes.
- Mounjaro is a dual-action medicine that mimics the effects of GIP and GLP-1 hormones.
- It increases insulin release after meals and lowers the amount of sugar made by the liver.
- It slows down how quickly your stomach empties, helping you feel full and eat less.
- These effects together help reduce body weight and improve blood sugar control.
- It is given as a weekly injection and is approved for use in the UK for certain patients.
