Hello. Thanks for using this forum. Judging from your clinical situation, this seems to be related to IBS/ Colitis. However since you also complain of constantly having hyperacidity
along with constant diarrhea
, Zollinger Ellison Syndrome
also has to be ruled out, which presents with similar symptoms. You should perhaps go in for another round of upper and lower endoscopy
investigation and if possible also obtain a biopsy report from the above investigations. If you have further queries, be free to write in. Regards.
