Hi. Pain in IBS is generally caused due to bloating. The most commonly affected function in these diseases is transportation. In the stomach and small intestine
, the symptoms of slowed transportation are nausea, vomiting, abdominal bloating
(the sensation of abdominal fullness), and abdominal distention (enlargement). The symptom of rapid transportation usually is diarrhea. In case you are suffering from severe pain
in the right hypochondriac region then i would suggest you to consult a surgeon so that gall bladder
involvement can be ruled out.
