Mounjaro (Tirzepatide) for Weight Loss
What is Mounjaro?
Mounjaro (tirzepatide) is a prescription medication used to support weight loss and improve metabolic health. It belongs to a newer class of medications known as GLP-1 and GIP receptor agonists, which mimic natural hormones in the body that regulate appetite, blood sugar, and digestion.
Originally developed to treat type 2 diabetes, Mounjaro has also been shown to produce significant and sustained weight loss when used alongside healthy lifestyle changes such as improved nutrition and increased physical activity. Treatment is administered as a once-weekly injection, making it a convenient option for people looking for long-term weight management support.
How Mounjaro Works
Mounjaro works by activating two key hormone pathways involved in appetite and metabolism:
1. Appetite regulation
The medication signals the brain that you feel full sooner and for longer, helping reduce hunger and food cravings.
2. Slower stomach emptying
Food stays in the stomach for longer, which increases feelings of fullness after meals.
3. Improved blood sugar control
Mounjaro helps the body release insulin more effectively and reduces excess glucose production in the liver.
Together, these effects help reduce calorie intake and support steady, sustainable weight loss.
Clinical Results
Clinical trials have shown that tirzepatide can lead to substantial weight loss when combined with lifestyle changes.
In major studies involving adults with obesity or overweight:
-
Participants lost up to 20–22% of their body weight over approximately 72 weeks.
-
Many individuals achieved 15% or greater weight reduction, which is considered clinically significant for improving overall health.
-
Improvements were also seen in blood pressure, cholesterol, and blood sugar levels.
Individual results can vary depending on factors such as starting weight, dose adjustments, lifestyle habits, and adherence to treatment.
Common Side Effects
Like all medications, Mounjaro can cause side effects. These are usually mild to moderate and often improve as the body adjusts to treatment.
Common side effects may include:
-
Nausea
-
Reduced appetite
-
Vomiting
-
Diarrhoea
-
Constipation
-
Stomach discomfort
-
Fatigue
Side effects are often reduced by starting at a lower dose and gradually increasing over time under clinical supervision.
Serious side effects are rare but will be discussed during your consultation. You will always have the opportunity to speak with a clinician if you have concerns during treatment.
Who May Qualify for Treatment
Mounjaro may be suitable for adults who:
-
Have a BMI of 30 or above, or
-
Have a BMI of 27 or above with weight-related health conditions (such as high blood pressure, prediabetes, or sleep apnoea)
Treatment may not be suitable for individuals who:
-

-
