“See a GP if you have any of the symptoms of type 2 diabetes or you’re worried you may have a higher risk of getting type 2 diabetes,” advises the NHS.
“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.
As the NHS points out, early treatment reduces your risk of other health problems.
