I'm sorry, I don't know anything about glucose intolerance. I do know, however, that stress can cause alot of physical problems. You could also be gluten intolerant, even though you do not have Celiac disease. You might try a gluten-free diet for awhile and see if things improve.
Good Luck to you.
Iv'e had a chronic stomach disorder and fatigue for about 5 years. Test's?? Iv'e had everything under the sun and all is negative. Even stomach biopsy. No celiac. Can't figure out what it is. Could I be glucose intolerant. Stess have anything to do with it? Need help.
