NHS Weight Loss Injections Available in England
The NHS currently provides access to clinically approved weight loss medications such as tirzepatide (Mounjaro®) through a phased national rollout.
Prescribing began within general practice in 2025 and continues to expand gradually under new GP funding incentives introduced for 2026/27.
However, treatment remains prioritised for patients at highest clinical risk.
Current NHS Eligibility Criteria
Patients must:
✅ Be aged 18 or over
✅ Have a Body Mass Index (BMI) of:
- 40 or higher, or
- 37.5 or higher for certain ethnic groups
AND
✅ Have multiple obesity-related health conditions, including:
- Type 2 diabetes
- High blood pressure
- Cardiovascular disease
- Obstructive sleep apnoea
- Abnormal cholesterol levels
- Severe mobility limitations
Expected Eligibility Changes From 2026
Eligibility thresholds are expected to widen slightly under the next NHS contract period:
- BMI ≥35 with four weight-related conditions
OR - BMI ≥40 with three weight-related conditions
Despite expansion, NHS treatment will continue to prioritise patients with significant medical complications first.
Why Many Patients Do Not Qualify
A large proportion of individuals seeking treatment fall outside NHS criteria.
You may not currently be eligible if:
- Your BMI is between 27–39
- You are seeking preventative treatment
- You do not yet have diagnosed medical conditions
- Local NHS prescribing pathways are not operational
This can be frustrating for patients motivated to improve their health earlier.
