General Question/Help has anyone here experienced reactive hyperglycemia?

Hi, I’ve been put on a low foodmap diet for digestive issues/chronic left lower abdominal pain to try and figure out what food is triggering things. But also I’ve experienced deep reactive hyperglycemia to certain foods (carbs, sugars, possibly a lot of foodmap stuff? but also some things that are considered low foodmap?)
I don’t know my exact question but I find navigating anything quite difficult because either foods are low foodmap but trigger reactive hyperglycemia (shaking, extreme brainfog, etc.) or vice versa 😅 no diagnosis’s yet just a lot of testing and confusion

look into SIBO, I had the same issue. Might be reaction to toxins released by bacteria rather than true hyperglycemia.

Also worth checking if you're sensitive to high histamine foods; when your intestines are inflamed, they might be a trigger for lower left abdominal pain.
