CO2 is odorless. There could be an overgrowth of CO2 producing bacteria present. If that's the case you probably exhale more CO2 in response to molecules like FODMAPS than a healthy person. You could consider taking a CO2 breath test. Most often they use sugar solutions but there are other options as well.
