Diarrhea can be caused by a variety of disorders that cause mucosal injury in the bowel, including viruses, bacteria, food poisoning, lactose intolerance, and ulcerative colitis. It can be acute, refractory, or chronic, and most people get better on their own without the need for medical therapy.
Chronic diarrhea is defined as diarrhea that lasts more than four weeks. If diarrhea has become persistent, it is important to remember that there might be a significant underlying ailment and that a medical examination should be obtained by contacting a physician. It is important to identify the illness that causes diarrhea and treat it properly in the treatment of diarrhea.
