I was on an outdoor tour of one week and had food in hotels. I also drank water from coolers at railway platforms. While returning back I had desentry watery stools with mucus for 4 days I took medicines from a General physician like Nexpro RD 20, Mohocef-oz, and Fos-lb and lomotil .my problem subsidised but I am not feeling healthy till date. Whenever I eat any food heavy or light my stomach is upset I pass softer stools and I think food is not assimilated completely my energy levels are low and dizziness persists. Please assist what all tests are required and whom to consult.
