Type 2 diabetes screening

The NHS doesn't routinely screen people for type 2 diabetes, but tests may be arranged if a person sees their doctor about certain symptoms, or if they are at a higher risk of developing the condition.

Left untreated, high blood sugar levels from type 2 diabetes can cause complications over time, including eye, nerve, and kidney damage.

Risk factors for developing type 2 diabetes include:

  • Being over 40
  • Having a close family member with diabetes
  • Being overweight or obese
  • Having certain ethnic backgrounds, including south Asian, Chinese, African-Caribbean or black African

Type 2 diabetes symptoms include:

If you have any of these symptoms, seek medical advice. Your doctor may check your urine or blood for blood sugar (glucose). Depending on the results, type 2 diabetes may be diagnosed and treatment and lifestyle changes recommended.

If the results are borderline for type 2 diabetes, doctors may recommend changes such as getting to a healthy weight, taking more exercise, and eating more healthily, to help prevent or delay diabetes developing.
