This guideline covers the care and management of type 2 diabetes in adults (aged 18 and over). It focuses on patient education, dietary advice, managing cardiovascular risk, managing blood glucose levels, and identifying and managing long-term complications.

In May 2017 we added text on sodium–glucose cotransporter 2 (SGLT-2) inhibitors to the section on initial drug treatment. We also updated the algorithm for blood glucose lowering therapy in adults with type 2 diabetes to revise footnote b with links to relevant NICE guidance on SGLT-2 inhibitors, and added new information on SGLT-2 inhibitors to the box on action to take if metformin is contraindicated or not tolerated.

Recommendations

This updated guideline includes new recommendations on:

Who is it for?

  • Healthcare professionals that care for adults with diabetes
  • Commissioners and providers of diabetes services
  • Adults with type 2 diabetes, and their families and carers

Guideline development process

How we develop NICE guidelines

This guideline updates and replaces NICE guideline CG87, NICE guideline CG66, NICE technology appraisal guidance 248 and NICE technology appraisal guidance 203.

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.
