Hi. Thanks for your query. Noted the history one year of suffering with severe stomach pain, vomiting, diarrhea, nausea, blood in stool, scoped and had camera scopy too, gall bladder removed without any positive effect, on third hernia repair, nothing has helped, using bathroom frequently, wants to know what can be wrong. After reading your history it looks that all the investigations are normal. I would advise you the following in addition: Stool test for three consecutive days. CT scan of the abdomen to rule out anything like tuberculosis. Tests for gluten and dairy intolerance. To make a list of the foods and beverages that cause the problems and to stop them altogether. If all the investigations are normal, this has to be treated on the basis of IBS.
