You're more at risk of developing type 2 diabetes if you:
- are over 40 (or 25 for south Asian people)
- have a close relative with diabetes (such as a parent, brother or sister)
- are overweight or obese
- are of south Asian, Chinese, African Caribbean or black African origin (even if you were born in the UK)
See a GP if:
- you have any of the symptoms of type 2 diabetes
- you're worried you may have a higher risk of getting it
Your GP can diagnose diabetes. You'll need a blood test, which you may have to go to your local health centre for if it cannot be done at your GP surgery.
The earlier diabetes is diagnosed and treatment started, the better. Early treatment reduces your risk of other health problems.
