I have type 2. I'm also having surgery this coming week. The nurse suggested I do a test to see how my sugar will act since I can't have anything to eat or drink after midnight the night before and am not supposed to take my meds the morning of the surgery. So I didn't have anything to eat or drink after 11 p.m. last night. I got up at 6:00 this morning and my sugar was 105. I tested it again at 9:45 after still not having anything to eat or drink and it was up to 134. I don't understand why it goes up when I'm not eating or drinking anything. I would think it would go lower. Can anyone explain this? It has had me completely baffled.

KatieH. I had surgery last September and like you my bs ran high when fasting
Doctor explained it was caused by being nervous. He said most everyone has this problem whether being diabetic or not. The calmest person will produce more incillian at stressful times.your body has a mind of its own.

Sometimes, if your sugar dips too low, your liver will release some glucagon to get it back up. But a BG of 105 is within normal BG ranges and probably didn't trigger a liver dump. Our bodies will frequently show higher blood sugars in the morning. You might want to research "Dawn Phenomenon" which causes high fasting BG's…but again, this doesn't appear to be what you experienced. Anxiety, illness, and stress can cause increased BG. Other hormones (but not insulin) like stress hormones, sex hormones, growth hormones and most metabolic hormones will cause your liver to release the sugar it has stored back into your bloodstream. Perhaps you're stressed about the upcoming surgery? I hope everything goes well for you.

I would point out that it was 105 3 hours and 45 minutes before she tested at 134 … plenty of time for normal activity to have dropped her BGL triggering a glycogen release

All I was doing during that time was watching TV.

We burn calories for energy just existing :) I found this chart that lists the calorie expenditure for various activities. I think it's interesting that reading burns more calories than watching TV. ~Lynn @Glucerna

One of the functions of the liver is to provide fuel in such situations (glycogen, which is stored glucose).
By 9:45 it got tired of waiting for an infusion of glucose from the breakfast you didn't eat and started dumping glycogen to keep you from going hypoglycemic.
That's over-simplified but it is one of the ways that your BGL can rise when you don't eat.
