About two days ago i had pretty bad abdominal cramp feelings, then i went to the bathroom but my bm was no joke longer than a foot long and soft. why?

Type of food?: The constitution of stool is predominantly bacteria and water. The bacteria present are determined in part by diet selecting out the organisms which prefer that food substance. The consistency is due, in part, to the amounts of liquid consumed and the capacity of the intestinal endothelium to absorb excessive fluid. The discomfrort is just the body's way of telling you it is time to defecate.
