adult screening programme


Diabetes is a long-term (chronic) condition caused by too much glucose (sugar) in the blood. It is also known as diabetes mellitus.

Type 1 diabetes occurs when the body produces no insulin. It is often referred to as insulin-dependent diabetes. It is also sometimes known as juvenile diabetes, or early-onset diabetes, because it usually develops before the age of 40, often in the teenage years.

Type 2 diabetes occurs when not enough insulin is produced by the body for it to function properly, or when the body’s cells do not react to insulin. This is called insulin resistance. Type 2 diabetes is far more common than type 1 diabetes.

UK NSC screening recommendation Based on the last UK NSC review of this condition that occurred in November 2019.

Screening is not currently recommended for this condition.

The UK NSC does not currently recommend screening for type 2 diabetes (T2DM). This is because:

  • there is no evidence that screening is more beneficial than not screening
  • there is no evidence that finding T2DM early by screening results in a greater health benefit than usual health care
  • more research is needed to review tests and benefits of screening for T2DM.
