How Does Fasting Affect A Blood Sugar Test?

396545384 Hi, and thanks in advance

I have been suffering from stocking and glove neuropathy for several weeks, and will be conferring with a neurologist. However, I am concerned in the meantime as I am sure you can understand. I am 27, and don't drink ever. They gave me a simple blood sugar test, and I came in at 107 after eating just hours before hand. Does this rule out diabetes as a cause.

I am literally praying for diabetes to be the cause. I know diabetes is serious, but I can work with that. It will make me take control of my diet, as I run 4 miles a day and still don't lose weight due to my poor eating. I have two aunts with MS, and this is what I lose sleep over.

It would seem to me that the fasting would only serve to lower a blood sugar level, but I am completely ignorant as to the physiology behind this disease. From everything I have read, diabetes is probably the least pernicious disease that could be causing these effects to someone of my age.

Thank you so very much for your help.

  1. gazeygoo - You are right fasting lowers blood sugar but in a diabetic that has no insulin to utilize the glucose the reading remains high even without the consumption of food. I don't think diabetes is your problem.

Kai - Sure, fasting should lower blood glucose but a healthy body, when it "feels" that no food is incoming and the body still need glucose to work (while you are fasting) will release stored glucose. If your body isn't releasing enough glucose during a fast, or if it's releasing too much, that gives the doctor a better picture of what might be happening (or not happening). 107 is just slightly high so your body might be insulin resistant (which is why more glucose isn't being burned up during your fast) or your body may not be putting out enough insulin during fasting time allowing your glucose to rise too high. You might be crossing into diabetes land but your doctor needs to compare your recent glucose levels to those you did before to see if it's been steadily getting higher or staying the same or what. Odd to hear someone prefer diabetes over some other thing but I do understand your thinking and hope you can be simply diabetic rather than something you have absolutely no ability to affect. You do need to clean up your diet no matter what. It would be so ironic if it was just an issue of not eating enough vegetables--I knew a homeless guy who refused to eat any vegetables (other than french fries and catsup) and he was always being hospitalized for leg and feet problems that seemed to baffle the doctors until I told him to mention his aversion to vegs; they started giving him vitamins and he got better.
