Overall objectives

This guideline provides recommendations based on current evidence for best practice in the prevention, early detection and early non-pharmacological and pharmacological treatment to reduce the risk of type 2 diabetes. It covers adults who are:

  • at risk of developing type 2 diabetes 
  • clinically diagnosed with prediabetes, impaired glucose tolerance, impaired fasting hyperglycaemia or previous gestational diabetes
  • recently diagnosed with type 2 diabetes.

It excludes children and the not-at-risk general population.

Management of type 1 diabetes (see SIGN 116 and SIGN 170) and the pharmacological treatment of people with type 2 diabetes (see SIGN 154) are not covered.

Further advice on the management of people with diabetes in pregnancy is available in SIGN 171.

Target users of the guideline

This guideline will be of interest to healthcare professionals in primary care, weight management services, psychology, maternal health and diabetes specialist clinics. It will also be of interest to those working in a wider community setting supporting comprehensive weight-management services, such as at leisure centres, community centres, workplaces and faith centres.

Lived-experience perspective

People with lived experience may have different perspectives on healthcare processes and outcomes from those of healthcare professionals. The involvement of people with lived experience in guideline development is therefore important to ensure that guidelines reflect their needs and concerns and address issues that matter to them.

Common concerns raised by groups and organisations as part of this process included:

  • ensuring that conversations are person-centred and sensitive
  • the need for timely information, support and advice
  • practical implications of being at risk of type 2 diabetes
  • the mental health of people who have been diagnosed with type 2 diabetes
  • the way people care for themselves before and after diagnosis is connected to quality of life.
