Considering injections for weight loss? Learn how Mounjaro and Wegovy work, who may be eligible, lifestyle support and how SynovaMed provides clinically supervised weight management in Leicester.
If you have been researching injections for weight loss, you have probably come across medicines such as Mounjaro® (tirzepatide) and Wegovy® (semaglutide).
These prescription medicines have become an increasingly recognised option for medically supported weight management in the UK. However, weight loss injections are not a quick fix or a treatment that should be used without appropriate clinical assessment. They are prescription medicines that should form part of a wider, personalised weight-management plan.
At SynovaMed, we provide clinically supervised weight management through our UK-registered pharmacy and qualified healthcare professionals. Our service is available online across the UK, with our pharmacy based in South Wigston, Leicestershire.
What are injections for weight loss?
Weight loss injections are prescription medicines that can help eligible adults manage their weight by influencing appetite, hunger and feelings of fullness.
Two of the most widely recognised options are:
- Mounjaro® (tirzepatide) – a once-weekly medicine that acts on both GIP and GLP-1 pathways.
- Wegovy® (semaglutide) – a once-weekly GLP-1 medicine used for weight management.
Both medicines are prescription-only and require an appropriate clinical assessment before treatment can be supplied.
They are intended to be used alongside a reduced-calorie diet and increased physical activity, rather than replacing healthy lifestyle habits.
How do weight loss injections work?
Medicines such as Mounjaro and Wegovy work on hormone pathways involved in appetite and food intake.
They can help you:
- Feel fuller for longer
- Reduce feelings of hunger
- Reduce food intake
- Manage appetite more effectively
- Make it easier to maintain healthier eating habits
The way these medicines work is different from traditional dieting. Rather than relying solely on willpower or calorie restriction, they can help regulate some of the biological signals involved in appetite.
However, individual responses vary. Not everyone will experience the same degree of weight loss, and treatment needs to be reviewed according to your response, health and tolerability.
Mounjaro or Wegovy: which weight loss injection is right for you?
There is no single best weight loss injection for everyone.
Mounjaro® (tirzepatide)
Mounjaro contains tirzepatide and acts on both GIP and GLP-1 receptors. It is administered once a week and may be prescribed for eligible adults as part of a medically supervised weight-management programme.
At SynovaMed, our Mounjaro weight loss treatment is supplied following a clinical consultation and prescriber assessment.
Wegovy® (semaglutide)
Wegovy contains semaglutide, a GLP-1 receptor agonist. It is also administered once weekly and is licensed in the UK for weight management in eligible patients.
You can learn more about our Wegovy weight loss injection and Wegovy weight loss pill, including treatment information and the clinical assessment process.
The appropriate medicine, dose and treatment plan depend on your individual circumstances. A clinician should consider factors such as your BMI, medical history, current medicines, health conditions and previous weight-management attempts before prescribing.
Who can have weight loss injections in the UK?
Eligibility is not based on weight alone.
Depending on the medicine and prescribing pathway, eligibility can involve your BMI and whether you have weight-related health conditions. NICE recommendations for medicines used in weight management also set specific criteria, and private prescribing requires an individual clinical assessment.
For example, NICE recommends tirzepatide as an option for managing overweight and obesity in adults with an initial BMI of at least 35 kg/m² alongside at least one weight-related health condition, with lower BMI thresholds applicable in certain circumstances.
Your prescriber will assess your circumstances rather than simply relying on a BMI number.
At SynovaMed, our online consultation takes only a few minutes. Your information is reviewed by a UK-registered prescriber to determine whether treatment may be clinically appropriate.
If treatment is not suitable for you, it will not be prescribed.
Are weight loss injections safe?
Prescription weight loss injections can be appropriate for eligible patients when prescribed and monitored correctly. However, like all medicines, they can cause side effects and are not suitable for everyone.
Common side effects can include:
- Nausea
- Diarrhoea
- Constipation
- Vomiting
- Abdominal discomfort
- Reduced appetite
Side effects can be more noticeable when treatment is started or when the dose is increased.
This is why gradual dose escalation and appropriate clinical supervision are important.
If you experience unexpected or severe symptoms, you should seek appropriate medical advice rather than simply continuing treatment.

Weight loss injections should be part of a lifestyle plan
One of the most important things to understand about weight loss injections is that medication works best as part of a broader approach.
At SynovaMed, we believe weight management should go beyond simply supplying a prescription.
While taking your prescribed treatment, you should continue working towards sustainable lifestyle habits, including:
Eat a balanced diet
Focus on nutritious foods that provide protein, fibre, vitamins and minerals. Smaller portions may become easier to manage as your appetite changes, but it remains important to prioritise nutritional quality.
Stay physically active
Regular physical activity can support overall health, fitness and weight management. Choose activities that are realistic for your lifestyle and that you can maintain consistently.
Prioritise protein
Adequate protein intake can help support muscle maintenance during weight loss. Your individual nutritional needs can vary, so consider discussing your diet with an appropriate healthcare professional if you are unsure.
Drink enough fluids
Reduced appetite can sometimes mean that people also eat and drink less than they normally would. Staying hydrated remains important throughout treatment.
Build habits you can maintain
The aim should not simply be to reach a particular number on the scales. Developing sustainable eating, activity and lifestyle habits can help support your long-term health.
What happens when you stop weight loss injections?
Weight management is a long-term process.
Some people may experience increased appetite or regain some weight after stopping treatment. This does not mean that treatment has failed. Weight regulation is complex, and maintaining changes after medication requires ongoing attention to nutrition, physical activity and other lifestyle factors.
You should never stop or change your prescription without discussing it with your prescriber.
Your treatment should be reviewed according to your progress, side effects, health and longer-term goals.

No.
