Will I be prescribed Mounjaro for weight loss?
Our doctors strictly follow the prescribing guidelines for GLP-1 Medications for the purpose of weight-loss. We can only prescribe the medication for patients who have a BMI greater than 30 (in some circumstances a BMI of 27 with one weight related problem will fulfil the criteria, your doctor will confirm). We can intiate these medicines if you do not have diabetes or if you have type 2 diabetes, but we do not start Mounjaro or Ozempic if you have type 1 diabetes.
How does Mounjaro work for weight loss?
It contains Tirzepatide, a drug mimicking glucagon-like peptide-1 (GLP-1), a naturally occurring hormone that the gut releases after every meal. The injection binds to GLP-1 receptors in the brain to increase the feeling of fullness and control appetite. This helps reduce food intake, decreasing the calories consumed, which aids weight loss.
Is this weight loss treatment right for me?
Your doctor will assess your circumstances to determine whether weight loss treatment is suitable. Adults who are overweight or have obesity with at least one weight-related condition like type 2 diabetes or high blood pressure can use this injection. The doctor will also evaluate the following to determine if you are suitable:
- Current health condition
- Medical history
- Current medications

People who took the injection had an average weight loss of 15 – 20% than the 2 – 3% of those on the placebo. However, the results may vary depending on individual factors like lifestyle, commitment to treatment and starting weight.
