Diarrhea

Diarrhea is loose, watery stools occurring more than three times in one day. It usually goes away on its own without any special treatment. However, prolonged diarrhea can be a sign of other problems. Victims of diarrhea may pass more than a quart of stool a day.

Symptoms

Diarrhea may be accompanied by cramping abdominal pain, bloating, or nausea. The victim may also have a fever or bloody stools.

What causes diarrhea?

Diarrhea may be caused by a temporary problem, like an infection, or a chronic problem, like an intestinal disease. A few of the more common causes of diarrhea are

Bacterial infections. Several types of bacteria, consumed through contaminated food or water, can cause diarrhea. Common culprits include Campylobacter, Salmonella, Shigella, and Escherichia coli.

Viral infections. Many viruses cause diarrhea, including rotavirus, Norwalk virus, cytomegalovirus, herpes simplex virus, and viral hepatitis.

Food intolerances. Some people are unable to digest some component of food, such as lactose, the sugar found in milk.

Parasites. Parasites can enter the body through food or water and settle in the digestive system. Parasites that cause diarrhea include Giardia lamblia, Entamoeba histolytica, and Cryptosporidium.

Reaction to medicines, such as antibiotics, blood pressure medications, and antacids containing magnesium.

Intestinal diseases, like inflammatory bowel disease or celiac disease.

Functional bowel disorders, such as irritable bowel syndrome, in which the intestines do not work normally.

Diarrhea Treatment

In most cases, replacing lost fluid to prevent dehydration is the only treatment necessary. Medicines that stop diarrhea may be helpful in some cases, but they are not recommended for people whose diarrhea is caused by a bacterial infection or parasite-stopping the diarrhea traps the organism in the intestines, prolonging the problem. Instead, doctors usually prescribe antibiotics. Viral causes are either treated with medication or left to run their course, depending on the severity and type of the virus.
