Hi. I have gone through the list of medical history and your problems. It makes me think of possibilities of many problems like internal fistula, very lax anal sphincter, irritable bowel syndrome
and so on. You need to get thoroughly investigated and I would suggest you to review your present medical problems ans their medications, all relevant blood , urine and detailed stool test
, Enteroclysis ( contrast enhanced visualization of small and large bowel, CT scan
of abdomen and a colonoscopy
. In the meantime stop all food and beverages which increase this problem. Stop taking over the counter medicines for the time-being as they interfere with reports... All these reports will decide the mode of treatment as this does not look like routine intestinal infection...
