I had ileocecal removed along with small intestine resection in 1999. About 2014 started having lots of belching and it has gotten worse with time. I also have a hiatal hernia that has been around several years. I did a sibo test in 2015 and was negative for sibo. Recently visited with GI MD and he wants to redo the sibo test. My question here: Anyone experiencing lots of belching/gas with hernia? Thanks
