Type 2 Pathway - Screening

Who to screen for diabetes

Type 2  diabetes is a progressive condition. Early diagnosis and treatment can significantly reduce the risk of complications resulting from diabetes. Whilst type 2 diabetes can present with symptoms such as polyuria, nocturia, fatigue etc. it is likely that diabetes has been present for years before symptoms develop.

It is therefore important to actively screen people, particularly at risk people, for diabetes.
