Losing weight can be challenging, and many people are now exploring prescription weight-loss injections. In fact, NHS data shows that around one in four adults in the UK are living with obesity, making effective weight management an important public health priority.
Two of the most talked about treatments for weight loss are Wegovy and Mounjaro. Both are available in the UK, but they work differently and can affect people in unique ways. So, when it comes to Wegovy vs Mounjaro, which is better for you? Let’s look at their results, side effects, and what people are saying.
What is the difference between Wegovy and Mounjaro?
Wegovy contains semaglutide, a GLP-1 receptor agonist. It mimics a natural hormone in the body that slows digestion and helps you feel full for longer. This can reduce appetite and calorie intake over time.
Mounjaro contains tirzepatide, which targets two hormones instead of one: GLP-1 and GIP. This dual action not only supports appetite control but also improves how the body uses insulin. Because of this, some studies suggest Mounjaro may produce greater weight loss than Wegovy for some patients.
Wegovy weight loss results
Clinical studies show that Wegovy users can lose around 15% of their body weight over 68 weeks when combined with diet and exercise support.
Mounjaro weight loss results
Research into Mounjaro suggests that some patients achieve even higher weight reduction, with reports of 20% or more in trials. However, individual results always vary.
What are the side effects of Wegovy vs Mounjaro?
Both injections can cause side effects, and it is important to understand them before starting treatment.
Common Wegovy vs Mounjaro side effects
- Wegovy: nausea, constipation, tiredness, and diarrhoea.
- Mounjaro: nausea, vomiting, reduced appetite, and diarrhoea.
Serious but less common side effects

When looking at Wegovy vs Mounjaro side effects, they are broadly similar, although some users find one treatment easier to tolerate than the other.
What do reviews say about Mounjaro vs Wegovy in the UK?
When reading Mounjaro vs Wegovy reviews, many patients highlight improved confidence and better health outcomes, especially when weight loss supports conditions such as high blood pressure or diabetes.
Some users report faster weight loss with Mounjaro, while others prefer Wegovy, as it has been available in the UK for longer and is supported by more extensive real-world evidence.
It is worth remembering that lifestyle changes, diet, and physical activity remain essential alongside these injections.
Wegovy vs Mounjaro: which is better for you?
Everyone’s weight-loss journey is different, so the better choice is the one that fits your needs. If your main goal is consistent and well-documented results, Wegovy may be the right option.
