Can I Get Weight Loss Injections on the NHS? (October 2026)

01 · NHS eligibility

Who can get weight loss injections on the NHS?

People with the highest clinical need come first. NICE recommends Mounjaro for adults with a BMI of at least 35 plus at least one weight-related condition. The NHS primary-care rollout began in June 2025, initially for BMI 40+ with four or more qualifying conditions.⁴⁶

NHS access to Wegovy runs through specialist weight-management services; ask your GP. See our guides on how to get weight loss injections from the NHS and the Mounjaro injection on the NHS.

02 · Next steps

How do I ask my GP?

Book an appointment, ask for a weight management review, and bring your height, weight and any conditions such as high blood pressure, high cholesterol, sleep apnoea, prediabetes or type 2 diabetes. Your GP can say whether you fall into a current rollout group or should be referred to a specialist weight management service. Ask about waiting times, as availability varies by area.

04 · Ethnic background thresholds

Does ethnic background change the BMI threshold?

Yes. People from South Asian, Chinese, other Asian, Middle Eastern, Black African or African-Caribbean backgrounds are at higher risk of weight-related health problems at a lower BMI, so clinical thresholds are usually reduced by 2.5 kg/m² for these groups.⁴ Ask your GP how this applies to you.

05 · What treatment involves

What does Mounjaro do and how well does it work?

Mounjaro is a once-weekly injection that activates GIP and GLP-1 receptors, helping you feel fuller sooner and less hungry between meals.¹ In the SURMOUNT-1 trial of 2,539 adults, people lost on average 15% of body weight on 5mg, 19.5% on 10mg and 20.9% on 15mg over 72 weeks, versus 3.1% with lifestyle changes alone. These are trial averages; individual results vary, and treatment works alongside a reduced-calorie diet and increased physical activity.²

Everyone starts on 2.5mg weekly, then steps up after at least 4 weeks on each dose, depending on how you respond, to a maximum of 15mg.¹

06 · Safety and contraception

Safety points to know before starting

The most common side effects, affecting more than 1 in 10 people, are nausea, diarrhoea, vomiting, constipation and abdominal discomfort, and they usually ease within days to a few weeks.¹³ Get medical help straight away for severe, persistent stomach pain that may spread to your back, with or without vomiting (possible pancreatitis); pain in the upper right abdomen, fever or yellowing of the skin or eyes (possible gallbladder problems); or signs of a severe allergic reaction such as swelling of the face or throat and difficulty breathing.¹³

Mounjaro slows stomach emptying, which can reduce how well oral contraceptive pills are absorbed. Switch to a non-oral method, or add a barrier method such as condoms, for 4 weeks after starting and for 4 weeks after each dose increase. This applies to the pill only.⁷ Mounjaro must not be used during pregnancy, and it should be stopped at least one month before trying to conceive; if you become pregnant during treatment, stop the medicine and tell your prescriber promptly.¹
