The full answer
Yes, for the same reason it causes bloating
Excess gas is closely related to bloating in celiac disease — both stem from malabsorbed food reaching the colon and being fermented by gut bacteria instead of being properly digested higher up in the small intestine.
It usually improves with treatment
On a strict gluten-free diet, as the intestine heals and absorption improves, gas and bloating typically ease significantly — see how long it takes to feel better for a realistic timeline.
