Weight loss injections have become a major topic of interest in recent years. This is particularly with the increasing use of medications like Mounjaro, Wegovy, and Saxenda. With the rise of GLP-1 receptor agonists, which were originally developed for diabetes treatment, they are now recognised for their ability to regulate appetite, reduce food cravings, and promote significant weight loss when combined with lifestyle changes.
Across the UK, the demand for safe, effective weight loss medications is growing. The NHS has introduced structured weight management pathways, including limited access to prescription weight loss injections for eligible individuals. However, these treatments are not available to everyone and are only provided under specific clinical conditions.
What Are Weight Loss Injections?
Weight loss injections are medications that help regulate appetite and blood sugar levels, making it easier to lose weight. Most of these weight loss medications are GLP-1 receptor agonists. They mimic a natural hormone that targets areas involved in appetite regulation.
Popular GLP-1 weight loss injections in the UK include:
- Wegovy (semaglutide)
- Saxenda (liraglutide)
- Mounjaro (tirzepatide)
These treatments are typically offered to people with a high body mass index (BMI) and obesity-related health risks, especially when diet and exercise alone have not been effective.
NHS Weight Loss Injection Eligibility
The NHS weight loss criteria are designed to ensure that treatment is provided to those who need it most and can benefit from it. These are only available after referral to a specialist NHS weight management service and under strict criteria usually determined by BMI levels and the presence of weight-related conditions.
You may be eligible for weight loss injections on the NHS if:
- You have a BMI of 35 or above
- BMI of 30 with an obesity-related condition such as type 2 diabetes, hypertension, or sleep apnoea
- You are enrolled in a specialist NHS weight management service
- You are committed to long-term lifestyle changes, including diet and physical activity
- Other weight loss interventions have not been successful on their own
These eligibility criteria may vary slightly depending on the local NHS trust or Integrated Care Board (ICB).
Wegovy Prescription UK: NHS Access Explained
Wegovy (semaglutide) is one of the most popular weight loss injections currently approved in the UK. In 2023, NICE (National Institute for Health and Care Excellence) approved Wegovy for NHS use for adults with a BMI over 35 and at least one weight-related condition, when prescribed through a specialist weight management service.
Remember, you cannot get Wegovy directly from your GP. It must be prescribed as part of a supervised programme within the NHS. This ensures safety and proper monitoring of side effects and results.
Saxenda on the NHS
Saxenda (liraglutide) was previously available on the NHS through specialist services and some pilot schemes. While it is still used in certain cases, many NHS clinics have now shifted to offering Wegovy due to its once-weekly dosing and more sustained weight loss results.
Under the given NHS criteria, Saxenda is given as a daily injection prescribed for adults with a BMI of 35+ and those above the age of 75.
Patients who started Saxenda treatment before the switch may continue, but new patients are more likely to be started on semaglutide (Wegovy).
How to Get Mounjaro on the NHS?
From June, 2025, the NHS in England has begun a rollout of Mounjaro. Eligibility is initially limited, applying to patients with:
- BMI over 40
- At least 4 or 5 obesity related conditions (type 2 diabetes, hypertension, high cholesterol, cardiovascular disease, obstructive sleep apnoea)
If you are interested in how to get Mounjaro on the NHS, keep an eye on NICE updates and speak to your GP for the latest information.
NHS Obesity Clinic Referral: The First Step
To access NHS weight loss injections, you will typically need a referral to an NHS obesity clinic. These are specialist Tier 3 or Tier 4 services that offer multidisciplinary care, including doctors, dietitians, psychologists, and exercise specialists.
Your GP can refer you to these services if you meet the NHS weight loss criteria. Once accepted, your care team will assess your needs and may recommend weight loss medications based on the eligibility criteria.
Weight Management Services NHS: What to Expect
NHS weight management services are structured in tiers:
- Tier 1: Universal services like public health campaigns
- Tier 2: Community-based diet and exercise programmes
- Tier 3: Specialist weight management services with medical supervision
- Tier 4: Surgical interventions like gastric bypass
Weight loss injections are usually initiated in Tier 3 or Tier 4 settings after a comprehensive assessment and lifestyle support.
Final Thoughts
Accessing weight loss injections on the NHS is possible for individuals who meet specific criteria and guidelines. If you think you may qualify, speak to your GP about an NHS obesity clinic referral and take the first step toward better health.
