Re: low blood sugars after eating and can't stay awake sometimes, anyone experience t
As far as the insulinoma goes (insulin producing tumor), your BG is much higher than it would be with an insulinoma most likely. I was tested for this, and the cut off is 45. That means your FASTING BG is under 45 constantly. It doesn't sound like you have major reactive hypoglycemia with BG of 75 after a large amount of carbs. You may have some, but its hard to tell since BG readings are "snapshots". I have LADA, which is slow onset T1 diabetes. Right now, it presents mostly as SEVERE reactive and fasting hypoglycemia. I mean that I am 50 or less every half hour to an hour, regardless of what I eat, carbs or no carbs. Then I intermittently have days where I am 200-300 for hours before going low again.
When I'm low, I feel slight nausea or some confusion. When I'm REALLY low, I feel like I'm uncontrollably falling asleep, REALLY confused, I can't talk, I don't know what I'm doing. When I'm 30, I can't see.
I think the GTT is a good move to see if you are having blood sugar problems. I don't think you should give up trying to find out what is causing your symptoms, blood sugar related or not. Chronic fatigue is never fun to deal with.
Good luck tomorrow.
