Acidophilis may be good for general bowel health for everyone including IBSers but the research shows it likely will not be helpful for managing IBS symptoms. It sure cannot hurt to take it
IBS is consider a disorder of the bowel which includes the large and small intestine but definitely not the pancreas. It is thought to be a dysfunction within the intestines. IBSers may experience some secondary stomach issues such as nausea but it is not the primary site of IBS. IBS can co-occur with other functional GI disorders such as GERD and functional dyspepsia. I rarely experience stomach discomfort unless I have a severe IBS attach and then I experience some nausea.
