Q.

Cake

Hi
If you have something very sugary right before you go to sleep, like a slice of cake, I am not diabetic, and you get a fasted glucose reading of 5.8, will the cake have an effect on the reading in the morning?

Hi Kat
Glucose in your blood comes from what you eat and what your liver produces. Your morning fasting reading, presuming you have had nothing to eat in the last 8 hours, will reflect what your liver is producing and not the food you ate the night before. According to SA guidelines, a fasting glucose(done in the morning after fasting for 8 hours) is considered normal if it is less than 6.1, pre-diabetes if it is between 6.1 and 7, and diabetes if it is 7 or more.
