Cheers Jim, took your advice and it said Low insulin coupled with physical activity stimulates the secretion of several other hormones such as epinephrine, norepinephrine, cortisol, glucagon, and growth hormone. Collectively these hormones trigger the liver to release glucose into the blood, thereby increasing the BG rather than decreasing it. Maybe I should just stop runningrwm1561
I cannot give you a logical explanation but I do know that after strenuous exercise your levels can initially rise. If you google the question I am sure you will get an explanation, or, somebody more knowledgeable than me will come along!

Cheers Mo, One benefit is that on longer runs I wont need to buy any energy drinks as the old liver will be supplying its ownDon't give up the running. Just understand that the BG rise is a natural occurance and is tempory. The benefits of regular exercise far outweigh the occasional temporary rise in your levels.

Yes, the "BG up = carbs eaten" is a ridiculously oversimplified lie-to-children which falls apart all the time. Simply put, hormones (e.g. released in response to stress, exercise, illness) have a massive impact on BG but this is a little known fact (e.g. cortisone injections can induce hyperglycemia in healthy people without a change in diet).is there a logical explanation for this?
Hi Alex,I will certainly give the book a try.Yes, the "BG up = carbs eaten" is a ridiculously oversimplified lie-to-children which falls apart all the time.

If you keep exercising, you will get better at the activity and should expect less of a rise from the same activity (e.g. 30min running at 10km/h); on the other hand, you may want to increase the intensity as you get better, counteracting this.
If you want to know more, I'd suggest this book
Is it normal for blood sugar level in type 2 diabetics to rise after exercise?
Last night my reading was 4.7 before running 5Km and straight after this had risen to 7.5. I would have expected the reading to go down if anything not up, is there a logical explanation for this?
i run approx 55 kms per week in 13/14 km bouts. early in morning without food. only drink diluting juice beforehand (about 1 litre) generally get a spike at end of run. but returns to normal around . a reading of 5 within 30 mins of finishing. doctor says thats ok. keep up the running. better to exercise than not. good luckIs it normal for blood sugar level in type 2 diabetics to rise after exercise?

Cheers Phil,intend to keep it up and maybe even get one more marathon in ( last one was 1987 )i run approx 55 kms per week in 13/14 km bouts. early in morning without food. only drink diluting juice beforehand (about 1 litre) generally get a spike at end of run. but returns to normal around . a reading of 5 within 30 mins of finishing. doctor says thats ok. keep up the running. better to exercise than not. good luck

Cheers Bebo321 will have a look at Team BG over the weekend.Hi there,
Your liver is kicking out glucose as a stress response to your higher heart rate - you are obviously working quite hard when you run, which is great. What you may find however is if you want to bring your blood glucose levels down, just run a little slower, or combine your running with a bit of walking.
For more information around exercise and type 2 diabetes, take a look at
http://www.teambloodglucose.com/TeamBG/Kit_bag_Exercise.html, and find the explanation for what happens to blood glucose levels with moderate exercise, when compared to higher intensity exercise.
Keep up the running!
Yes! This took me a while to find out and am glad I know, I'm type 1 with a pump so think it's easier for me. I cycle and find before excising I need to up my sugar and reduce my insulin. During exercise your liver produces glucose and feeds your muscles. This sugar stays around after you stop exercising plus your muscles then 'dump' the excess glucose back into your blood stream for your body and pancreas to sort. After exercise I have to increase my pump to 200% and give a bolus to compensate. Go to run sweet website. That's helpful. I'm not sure how you tackle this as a type 2. Good luck.
Yes this is a well known, if not well understood, phenomenon, I do 2 minutes of fierce exercise on my exercise bike (pushing up blood glucose if under 5.5) followed by 8 minutes of much milder exercise , this always lowers my bg, so need to be careful afterwards. I figure that the exercise is always beneficial and increases insulin sensitivity.
