Managing diabetes and excess weight often goes hand in hand. In the UK, more than 5.8 million people are living with diabetes — and nearly 1.3 million are thought to be undiagnosed. Many of these cases involve type 2 diabetes, which is closely linked to obesity and metabolic imbalance. This rising burden makes effective treatments that can address both blood sugar control and weight vital.
Mounjaro injections are one of the newest treatments designed to do both — helping with blood sugar control and supporting meaningful weight loss.
What is Mounjaro, and how does it work?
Mounjaro contains tirzepatide, a dual-acting ingredient that mimics two natural hormones in the body: GLP-1 and GIP. These hormones help regulate blood sugar and appetite. By activating both, Mounjaro supports better glucose control while helping you feel full for longer after eating.
Mounjaro for diabetes treatment
For adults with type 2 diabetes, Mounjaro improves how the body uses insulin and reduces blood sugar spikes after meals. It can be prescribed when diet, exercise, or other medicines do not give enough control.
Mounjaro for blood sugar control
By slowing digestion and reducing appetite, Mounjaro lowers the amount of glucose released into the bloodstream. This steady control helps reduce the risk of complications linked to diabetes, such as heart disease and nerve problems.
Can Mounjaro support weight loss too?
Yes. Mounjaro is also licensed in the UK for weight management in adults who meet specific BMI criteria. In the SURMOUNT-1 clinical trial, participants achieved up to around 20% body weight reduction when tirzepatide was used alongside a healthy lifestyle plan.
Mounjaro weight loss results
While individual results vary, many users experience gradual, sustainable weight loss over several months. The treatment helps manage appetite and food cravings, making it easier to stick to reduced-calorie eating habits.
Mounjaro vs Wegovy: what’s the difference?
Both Mounjaro and Wegovy weight loss injections belong to a class of treatments that mimic gut hormones. However, Wegovy contains semaglutide, which targets only GLP-1 receptors, while Mounjaro acts on both GLP-1 and GIP.
This dual action means Mounjaro may provide stronger effects for some people, although responses can vary. Both medicines require a pharmacist consultation to determine suitability.
What are the possible Mounjaro side effects?
Like all prescription medicines, Mounjaro can cause side effects. Most are mild and tend to improve as your body adjusts.
Common Mounjaro side effects include:
- Nausea or vomiting
- Constipation or diarrhoea
- Tiredness or low appetite
Less common but serious side effects include:
- Signs of pancreatitis (severe abdominal pain)
- Gallbladder problems
- Allergic reactions
Our pharmacists will review your health history before prescribing to ensure the treatment is safe and appropriate for you. If you experience severe or persistent symptoms, seek medical advice promptly.
Who can use Mounjaro injections?
Mounjaro may be prescribed to adults who:
- Have type 2 diabetes and need improved blood sugar control, or
- Have a body mass index (BMI) of 30 or higher (obesity), or
- Have a BMI of 27 or higher with a weight-related condition such as hypertension, high cholesterol, or type 2 diabetes
It is not suitable for everyone, including people with a history of pancreatitis or certain gastrointestinal conditions. A consultation with our pharmacists can help confirm eligibility and correct dosage.
What makes Mounjaro different from older treatments?
Older diabetes treatments often focused only on lowering blood sugar. Mounjaro represents a new generation of therapy that addresses both metabolic and weight-related health. Its dual hormone action offers improved glucose regulation and appetite control, helping to tackle the root causes of type 2 diabetes rather than just managing symptoms.
Should you consider Mounjaro for diabetes or weight management?
If you are struggling with type 2 diabetes, weight management, or both, Mounjaro could be an effective option to explore. However, it is not a first-line treatment and must always be prescribed following a professional consultation.

FAQs
Is Mounjaro available in the UK for both diabetes and weight loss?
Yes. Mounjaro is licensed in the UK for treating type 2 diabetes and for weight management in adults who meet specific BMI criteria. It can be prescribed after a pharmacist consultation to determine whether it is clinically appropriate for your needs.
How does Mounjaro help with weight loss compared to Wegovy?
Mounjaro activates two hormones — GLP-1 and GIP — while Wegovy targets only GLP-1. This dual action can enhance appetite control and improve how the body manages sugar and fat. Some studies show Mounjaro may support greater average weight loss than Wegovy, but results vary between individuals.
How long does it take to see results from Mounjaro injections?
Weight and blood sugar improvements can begin within the first few weeks, but most people see noticeable results after several months. The dose is increased gradually to reduce side effects and allow your body to adjust safely.
Can I use Mounjaro if I don’t have diabetes?
Yes, Mounjaro can be prescribed for weight management even if you do not have diabetes, provided you meet the BMI or weight-related condition criteria. Our pharmacists will assess your overall health before prescribing it.
What should I avoid while using Mounjaro injections?
You should avoid skipping doses or taking extra injections to speed up results. It’s also best to limit alcohol intake and continue following a balanced diet and activity plan. Always follow the dosing instructions provided by your pharmacist.
Are Mounjaro side effects common, and do they go away?
Mild side effects such as nausea, constipation, or tiredness are common and usually improve as your body adapts. Serious effects like pancreatitis or gallbladder issues are rare but require immediate medical attention. If symptoms persist, speak to our pharmacist promptly.
