DISCLAIMER
This article is for educational purposes only and should not replace professional medical advice. Always speak to your GP or a licensed healthcare provider before starting any weight-loss medication.
What is Mounjaro and How Does It Work for Weight Loss?
Mounjaro (generic name tirzepatide) is an injectable medication that mimics two natural hormones in the body: GLP-1 and GIP. These hormones play a key role in blood sugar regulation, appetite control, and digestion.
When used for weight loss, Mounjaro helps you feel full for longer, reduces cravings, and slows how quickly food leaves your stomach. This leads to a lower calorie intake and steady, sustainable weight loss.
Clinical studies show that people using Mounjaro for weight loss can lose up to 20% of their body weight over time when combined with a healthy diet and regular exercise.
Mounjaro for Weight Loss UK: Dosage and Starting Dose
If you’re starting Mounjaro for weight loss, your doctor or prescriber will begin with a low starting dose to help your body adjust.
Starting dose: 2.5 mg once per week
Titration: The dose is gradually increased every 4 weeks (to 5 mg, 7.5 mg, 10 mg, 12.5 mg, and up to 15 mg weekly)
Maintenance dose: Depends on your weight loss progress and tolerance
Never change your dose without consulting your prescriber. Starting low and increasing slowly reduces the risk of side effects such as nausea or bloating.
Mounjaro for Weight Loss Side Effects
Like any medication, Mounjaro can cause side effects — though most are mild and tend to ease as your body adapts.
Common side effects
Nausea or upset stomach
Diarrhoea or constipation
Fatigue or dizziness

Serious (but rare) side effects
Pancreatitis (inflammation of the pancreas)
Gallbladder issues
Kidney function changes (especially with dehydration)
Thyroid tumours (avoid if you have a personal/family history of thyroid cancer)
If you experience severe pain, vomiting, or other concerning symptoms, stop taking Mounjaro and contact your doctor immediately.
