Acute watery diarrhea is most commonly seen with traveler's diarrhea caused by enterotoxigenic E. coli (ETEC), parasite-induced diarrhea from Giardia and Cryptosporidium spp. and, in cases of food poisoning (ingestion of preformed toxins), from B. cereus and S. aureus.
Diarrhea is the frequent passage of loose, watery, soft stools with or without abdominal bloating, pressure, and cramps commonly referred to as gas or flatulence. Causes of diarrhea include viral and bacterial infections, as well as parasites, intestinal disorders or diseases, reactions to medications, and food intolerance. The main symptom of diarrhea is watery, liquid stools. Diarrhea is usually diagnosed by the appearance of the symptoms, and no tests may need to be ordered. In some cases a doctor may order a stool culture, blood tests, a colonoscopy, or imaging tests such as X-rays or CT scans to determine an underlying cause.
