What Is Mounjaro?
Mounjaro is the brand name for tirzepatide, a prescription-only weekly injection that helps adults lose weight under medical supervision.
Originally licensed for type 2 diabetes, Mounjaro’s ability to regulate appetite and blood-sugar levels has made it one of the most effective new options for medically supported weight management.
How Does Mounjaro Work in the Body?
Mounjaro mimics two natural hormones — GLP-1 (glucagon-like peptide-1) and GIP (glucose-dependent insulinotropic polypeptide).
Together they:
- Slow stomach emptying, helping you feel full longer.
- Reduce appetite and cravings.
- Improve insulin sensitivity, stabilising blood-sugar levels.
This dual action promotes gradual, sustainable fat loss without crash dieting.
Clinical Evidence
In clinical studies, participants using tirzepatide achieved an average 15–22 % body-weight reduction over 72 weeks when combined with diet and exercise.
Compared with earlier GLP-1 medicines such as semaglutide, Mounjaro’s dual-receptor activity often produces greater appetite control and more consistent weight loss.
Who Can Use Mounjaro?
Mounjaro may be prescribed for adults who:
- Have a BMI ≥ 30 kg/m², or
- Have a BMI ≥ 27 kg/m² with a weight-related condition such as type 2 diabetes, high blood pressure, or sleep apnoea.
A clinician must assess your suitability through an online or face-to-face consultation before prescribing.
