Occasionally, persistent diarrhea can be a symptom of a more serious condition, such as a chronic infection, inflammatory bowel disease, a malabsorption syndrome, or colorectal cancer. Persistent diarrhea can have many causes, including dietary changes, stress, irritable bowel syndrome, and certain medicines. Be sure to increase your intake of fluids, such as water or a rehydration drink, and to watch for symptoms of dehydration. Severe diarrhea increases your risk of dehydration by causing your body to lose large amounts of fluid quickly. This condition leads to leakage of solid stool, liquid stool, mucus, or gas. In extreme cases, the stool mass may injure the intestinal wall, causing bleeding, or breaking through it (perforation). Stool pressing on the intestinal wall also causes inflammation that may cause liquid secretion by intestinal wall tissue. Drinking untreated water that contains the Giardia lamblia parasite can cause diarrhea that develops 1 to 4 weeks later. It also is called fecal incontinence or anal incontinence. Sometimes liquid stool will work its way around the mass.

In simplest terms, poop is the body’s natural way of expelling the leftover waste and toxins that it doesn’t need once it’s absorbed all of the usable nutrients you consume from the foods you eat. Stomach flu ( gastroenteritis) or food poisoning may cause severe diarrhea. Poop (feces) is defined as waste matter that is discharged/excreted from the bowels after food has been digested. Mild diarrhea means having a few diarrhea stools in a day.Moderate diarrhea means having more than a few but not more than 10 diarrhea stools in a day.Severe diarrhea means having more than 10 loose, watery stools in a single day (24 hours).Proper evaluation is needed to investigate the precise cause. Other causes include severe infections of the lower gut. The commonest cause for such a situation is Piles. The severity of diarrhea is determined by the size and number of stools passed within a period of time. The fluid may be blood stained or you may get frank blood coming out of the anus. Diarrhea is described as an increase in the frequency of bowel movements or a decrease in the consistency of stools that causes the discharge of watery, loose stools.
