Weight-loss treatment on the NHS: am I eligible?
Short answer: the NHS does offer medical weight-loss treatment, but access is tightly rationed. It runs through specialist weight-management services and a phased GP programme that began with the highest-need group — adults with a BMI of 40 or more (lower for some ethnic groups) who also have several weight-related health conditions. Eligible patients are contacted directly by the NHS.
Educational, not medical advice. This page explains weight-loss treatment options in general terms. Only a registered clinician who knows your history can decide what's right for you.
The first-phase NHS criteria
The earliest group generally needs BOTH:
- A BMI of 40 or more (about 2.5 lower if you are from a South Asian, Chinese, other Asian, Middle Eastern, Black African or African-Caribbean background)
- Several weight-related health conditions, such as:
NHS treatment comes with wraparound support — diet and physical-activity advice — and is managed through your GP practice or a specialist service.
Why it's a slow rollout
The NHS is introducing GP-led treatment in stages to match capacity — planning to reach a large eligible group over its first few years. That's why the earliest access is limited to those at highest risk, widening over time. Eligible patients are identified from their health records and contacted by their GP, so there's no separate application to complete.
Not eligible yet? The private route
Most people who want treatment now don't yet meet the NHS criteria. The legal alternative is a GPhC-registered service, which begins with an online clinical assessment. Our UK pick is MedExpress (GPhC-registered online pharmacy (UK), CQC-regulated). Never obtain treatment without a prescription — the MHRA warns it's illegal and unsafe.
