Question from Fulton, Illinois, USA:
I have type 2 diabetes, and for the last week my levels have gone from 140 mg/dl [7.8 mmol/L] to 339 mg/dl [18.3 mmol/L] or higher. What would cause this?
A sudden change in blood sugars can indicate a serious health problem (such as an infection) which has nothing to do with your diabetes. You need to see a doctor right away to see what is going on.
