I had to wear my "fat pants" today. I don't seem to have gas but any pressure on my midsection gives me a false sense of urgent pressure to go the bathroom.
I think I might invest in some pregnancy pants because my legs swim in these pants.
Your Doc is trying to help, the root could be sibo or a lesser of - bacterial over growth. Probiotics might help. They can take time , like a month or more. and d can increase for a bit with bad bacteria die off
Also undigested carbs can cause bloat like white breads, sugars, even fruit juices. They also feed the bad bacteria.
NGNG is right - ditto simethiocone too.
