There are a number of reasons to fast for a number of different tests however for diabetics they usually want the to make sure the stomach is clear, and if there is any change in blood sugar then it is because of something your body is doing naturally, and is not because of something you have had to eat or drink.
Once again there are NUMEROUS things that simultaneously occur when you are diabetic so in terms of disconnecting your pump you will have to figure that out on your own. I am taking multiple injectins however the principle is the same. Our goal is to run the best sugars we can, in the SAFEST WAYS possible.
If you are not comfortable and think you need to eat then check your sugars and do whatever you think is necessaary to keep things SAFE and reasonable. Err on the side of caution and you can always reschedule the test if neessary. You know ALL the variables so work with them, around them and keep things in check. There is a process called gluconeogenesis which is a big word, but it is the reason EVERYONE’S sugar goes up while we sleep.
Only diabetics can actually “see” this on thier glucometer when they wake up because non diabetics have unknowingly, automatically made enough insulin to cover it. This is why you are best qualified to make the call because you know how much long acting insulin you usually have to take.
Diabetes is for the most part, an “ends justifies the means” type of thing, so do whatever you have to to make things work. Hang in, it’s not that long and stay safe!!!
