What is Mounjaro?
Mounjaro is a prescription-only, once-weekly injection used to help people lose weight by reducing hunger and regulating blood sugar levels. Its active ingredient, tirzepatide, works by mimicking natural hormones in the body that control appetite and fullness, making it easier to eat less and feel satisfied. In the UK, Mounjaro is approved for adults with obesity, particularly those who have additional health conditions related to excess weight, such as type 2 diabetes. Clinical studies have shown that people using Mounjaro can lose between 15% and 22% of their body weight over about 18 months, especially when combined with healthy lifestyle changes. Access on the NHS is currently limited to those with the highest clinical need, but private clinics do offer it after a medical consultation.
