Any well controlled diabetics here had a liver dump while having a bg over 100? I am on no meds, last A1C 5.3, exercise regularly, and the other morning that is just what happened to me, and I don't know why.

I usually eat about 30g of carbs before my 1 hour long morning run, but that morning I ate close to 50g. That run for some reason turned out to be more exhausting than usual. My bg afterwards usually come to about 120, rarely over 140, but that day was 183! I initially thought that was the result of that extra 20g of carbs, but half an hour later it rose to 241! At that point I start to suspect it wasn't the carbs but a liver dump?! I began to eat (again), but I am chicken, because if I was wrong and it wasn't a liver dump, the next number on that meter will be 300! and I've been fooled before…10g of carb and half hour later, 138! (I literaly hold my breathe when it came out!) another 10g and half hour later, 114.

I was certain my bg before that liver dump was well over 100. My blood suger is often at 70s,80s, and 90s without ever triggering a liver dump. Why did my liver release more sugar into blood while there was more than enough already?

I have some ideas of what may have happened, but I would love to hear what the experts on this forum have to say…TIA

Wow, I have never in my medical education (nursing school) heard anything about liver dumping? I'll definitely have to ask about this. Thank you for a new learning experience here.

I suppose there is a more technical term for it, but that is when some of the glycogen that is stored in your liver gets released into your blood stream. It is a cause of dawn phenomenon, adrenalin, and stress. If your body feels it needs energy to deal with a situation, the liver is told to send a dose into the blood stream. This is what metformin's main purpose is to help stop some of that.

So that is essentially what predawn phenomenon is? I have this issue and have settings on my pump just for this. every morning from 3-8 a.m., my basal changes for this factor. Is that where protein in the urine comes from is this? Wow..I just learned something awesome and new tonight. Thank you!

Just because there is a good amount of glucose in your blood it doesn't mean your body can use it. With diabetes, strenuous exercise can basically confuse your body and it can release glucose even when there is a lot already there, this can be especially true if you have reduced insulin production.

I appreciate your reply kd. Well, 1 hour run maybe strenuous, but that is what I do 3 times a week, every week. and this is the first confirmed liver dump I got in about 2 years of doing this…Your statement is very interesting yet lacks detail, would you like to further elaborate on that? Thanks

I think the key here is you said your run was more exhausting than usual. Your body was most likely stressed and caused your liver to release glucose. This happens to me when I over do it with the exercise also. I have learned to exercise so that my heart rate stays in a fat burning zone or at most the low aerobic zone. This keeps my heart rate low enough to not stress my body.

Thanks for the reply Diane. I thought the exhaustion was the result rather than the cause of the high blood sugar. As soon as I started to eat, I felt my energy started to come back. when I workout in gym I check my heart rate too, even though I don't know how accurate it is…but when I am running on the street, I just can't do that…Have you had any liver dumps after exercise? How high did your bg go to? Thanks for the advice about stress, I'll try to remember that.
