Good to hear you have no gas nor digestive problems!

I have a tortuous colon, bloated abdomen and constipation which may be unrelated. My internist taps my abdomen and declares it is my intestines "air" based on the echo she hears, I guess. I don't know what to do about it except slightly reduce my discomfort and "pot belly" by taking Beano before eating beans or cruciferous veggies. The constipation is an ongoing problem. This group is the closest I've come to find support and helpful feedback.

When you say your stomach is expanding, do you mean the capacity of your internal stomach? Or a bloated abdomen?
