This guideline covers how to identify adults at high risk of type 2 diabetes. It aims to remind practitioners that age is no barrier to being at high risk of, or developing, the condition. It also aims to help them provide those at high risk with effective and appropriate intensive lifestyle-change programme to prevent or delay the onset of type 2 diabetes. The 20 recommendations in this guideline can be used alongside the NHS Health Check programme.

It does not advocate a national screening programme.

NICE has also produced a guideline on preventing type 2 diabetes – population and community interventions.


This guideline includes recommendations on:

Who is it for?

  • GPs, nurses, pharmacists, occupational health specialists, optical practitioners and other health professionals
  • People at high risk of developing type 2 diabetes, their families and other members of the public

Is this guideline up to date?

Guideline development process

How we develop NICE guidelines

This guideline was previously called preventing type 2 diabetes: risk identification and interventions for individuals at high risk.

Your responsibility

The recommendations in this guideline represent the view of NICE, arrived at after careful consideration of the evidence available. When exercising their judgement, professionals are expected to take this guideline fully into account, alongside the individual needs, preferences and values of their patients or service users. The application of the recommendations in this guideline is not mandatory and the guideline does not override the responsibility of healthcare professionals to make decisions appropriate to the circumstances of the individual patient, in consultation with the patient and/or their carer or guardian.

Local commissioners and/or providers have a responsibility to enable the guideline to be applied when individual health professionals and their patients or service users wish to use it. They should do so in the context of local and national priorities for funding and developing services, and in light of their duties to have due regard to the need to eliminate unlawful discrimination, to advance equality of opportunity and to reduce health inequalities. Nothing in this guideline should be interpreted in a way that would be inconsistent with compliance with those duties.

Commissioners and providers have a responsibility to promote an environmentally sustainable health and care system and should assess and reduce the environmental impact of implementing NICE recommendations wherever possible.
