Can anyone enlighten me as to how liver function affects blood glucose,by that I mean at what level does the liver release glucose into your blood,if you dont eat for a prolonged time , or if you exercise hard,does that induce a glucose release. Is there a low level trigger ie BG falls below 4 mmol, hope this makes sense.I,m diet controlled and want to understand how to avoid the liver dump thing. thank you Dave.
 
Don't think its a straightforward answer to tbh. There are some known triggers to cause liver dumps regardless of level for diabetics/pre diabetic. You could have a normal pre bed reading, but wake up in double figures due to dawn phenomonan. If someone does have dawn phenomenon the level at which the bloods increase would vary greatly, depending on the level of insulin resistance or lack of insulin in that person. Certain types of exercise can cause a liver dump, again individual to how that persons body reacts to exercise. Stress is another cause. Only by testing and recording would an individual have an idea how much excercise, stress, illness, lows, effects not so much liver dumps but blood sugar levels.

I know that if you eat too much (i.e. Your stomach feels stretched / bloated) it causes the liver to release insulin to deal with the impending overload, but it also releases glucose to balance things out. Now being diabetic your body will release little (if any) insulin, but still the same amount of glucose.

Thats better now we are talking about it, am I right in thinking that moderate exercise is preferable to extreme bursts,ie pulse rate about 110 bpm for 20 -30 mins,to burn blood glucose but not trip into survival mode ?

As a general rule, low intensity prolonged cardio will reduce BG levels whilst heavy weights, competition or high intensity exercise will raise levels. There will always be exceptions to this and you need to test and see how your own body reacts.

Liver dump may also respond to a drop in BG levels to avoid hypo. With only 20-30 cams in circulation a bit of exercise soon sucks up the available glucose.

That's calories in circulation :-)

I'm a T2 who's new to all this, and I'm desperately trying to make some sense of it all. If it's of any help, my post prandial BG level of 10.1 at 12.00am this morning was pretty smartly brought down to 6.2 at 13:30 hours, by a 3-mile walk (done in under an hour, which was fast enough to make me pretty sweaty, despite a cool wind). That reduction was sustained through the afternoon and by 17:00 BG was down to 5.2 (which is the best I've recorded for a couple of weeks).

That's how I reacted, leastways on this occasion, and it would be nice to think I can do it all by exercise and dieting alone (I wish!) but I know it's not that simple.

Regards,

Tom.
 
2131 Tom, I,m new to this also, thats a big drop you had for a walk well done,I,m trying to make sense of it all too,What are cams ?There,s so much knowledge on this forum and I want to tap in to it.
I find a period of walking or cycling can drop my BG levels 2mmol,I,m low carbing as well which is working for me
I,m finding my feeling hungry trigger seems to be 5.5 or under it,s a real learning curve.Thanks for the replies thats helping me lots.

Hi, Snowballnc.

I'm finding that increasing exercise is helping me, but the relationship between what I'm eating, blood sugar, exercise etc. isn't as straightforward as I first thought it might be. Reading the posts on this Board has helped me realise that there's a complicated process going on, my body won't necessarily react in the same way as someone else's, and it'll take me a while to begin to figure out how I need to manage it all.

I do realise that the yo-yoing of my BS levels of late - the max I've now had is 14, last Thursday, (at which point I felt so lousy I went straight to the docs, who put me on Metformin) - has been causing me to feel so ill and, if I do get the levels down and more stable, that my body's going to take some time to adjust to lower levels than it's been used to (for goodness knows how long now), so I can't expect to feel great straightaway.

I just have to get on with it, I guess.

Cheers,

Tom.
 
Just seen this thread.
I find extreme bursts work better for me, I try to get my pulse into 140 or so (60 resting) on the treadmill, then the rower, for 20 minutes each, followed by resistance, then swimming, for about 2 hours overall.
I have to eat beforehand, or I find my bs drops.
