Everyone has or at least will experience diarrhea at some point in their life. Diarrhea is the term being used to describe the loose, more watery and more frequent bowel movements that occur for some reason. Most commonly, diarrhea only lasts for a couple of days at most, but it can go as far as to last a couple of weeks as well.
Diarrhea that lasts more than a couple of days is the usual sign that something more serious is happening inside the body - a problem which you must discuss with your doctor. The usual symptoms and signs of diarrhea are - loose, watery, and more frequent bowel movements, abdominal pain, stomach cramps, nausea, fever, the presence of blood in the stool, and bloating. Other symptoms might also be present, depending on the problem that is causing diarrhea in the first place.
Cause #1: Food Poisoning
Food poisoning happens when you eat food that has been contaminated with bacteria (or their toxins), viruses and/or parasites. The first symptoms will probably occur after two to six hours. Symptoms such as stomach cramps, fever, nausea, and vomiting will go along with diarrhea. It usually takes around two days for all of these symptoms to go away, but it can last as long as 2 weeks.
