I was reading some ones post and I think Kathleen had mention that IBS-PI can sort itself out in 2 to 5 years. Now I realize that might not be the case for all but what makes IBS-PI so different that it can sort itself? If you were to get another infection would it come back every time? If you were to get an infection or the Flu would/could it make your IBS worse permanently? Anyone have any answers/clues or is this what doctors are trying to figure out yet?
