Physiology question ...

[foxl]

Okay ... we know that blood sugar can go up during strenuous exercise, right?

But ... does it go up in healthy individuals, too? Or would a large rise post-exercise be an indication of IGT?

I would venture a "No"... normal people maintain their BG level in the normal range at all times -- homeostasis ;)

Although the liver and muscles may give up Glycogen as Glucose to be utilised during the activity... at the self-same time, insulin will be secreted as needed to make use of that Glucose energy.

That'd be my guess anyhoo :cool: ...and yes I'm sure I've oversimplified the physiology but the overall effect is doubtless as I have described.

Mine, too (great minds, Frank!) ... hoping to get a consensus for my Dear Husband ... who is in denial a bit still.

Nope, normal people have working pancreases. If you put me side by side with a doppleganger of me except for him having a working pancreas, at the end of a 5K race, his blood sugar will have hardly moved from the start whereas mine if I haven't tweaked any insulin injections to help, I can be anywhere from 50 to 150 mg/dL higher, although the quality of my data isn't all that exact and the variables aren't well controlled there.

Did you mean the blood sugar decreases? Thats what I thought that the insulin kicks in and decreases the bg,thus an individual could have a low blood sugar. Is this correct? am I missing something. Because when I do something strenuous or excercise my bgs are low.

Some people, including my husband, get an increase from strneuous exercise. Sometimes ... not always.
