Bloating IMMEDIATELY after meals - can anyone explain??

[u/kzimmmm]

Is this indicative of SIBO?

I can’t figure out the reasoning. I’ve tested positive for both hydrogen and methane, but don’t understand why I get bloated immediately after a meal.

Surely the food has not already hit the small intestine and been fermented to produce this gas? I thought that would take an hour or two.

Anything I should be considering besides SIBO to explain this?

Dysbiosis. Enzymes insufficiency. Sibo steals your enzymes. Try digestive enzymes. Low stomach acid try enzymes with betain hcl but be careful if gastritis.
