question: Hello doctor, Every once a month at least I get a flare up of diarrhea where I go at least six times a day and nothing seems to settle my stomach. The stool itself has a weird texture, almost sand-like. Most of it float down but some do float up and there is mucus in it. Other symptoms I am experiencing are lethargy, feeling of being full yet hungry, loss of appetite, and dry mouth. Any idea of what this could be?
