Diarrhea: what are the causes
Diarrhea is an abnormal evacuation of stool that has increased volume, fluidity, and frequency of emission. Excessively liquid stools are created due to excessive intestinal peristalsis, which leads to insufficient absorption of fluids by the intestines. In most situations this problem disappears in a few days. The persistence of the problem-as well as the presence within the stool of blood or pus-may be an indication of more serious medical conditions.
