Diarrhea is an increase in the frequency of bowel movements and the discharge of watery, loose stools. The person with diarrhea may also have abdominal cramps and nausea.
Diarrhea occurs when the intestines push stools through before the water in them can be reabsorbed by the body. It is your body’s way of quickly clearing out any viruses or bacteria.
Most diarrhea is caused by viral stomach flu (gastroenteritis). Some medications, especially antibiotics, may also cause diarrhea. For some people, emotional stress, anxiety or food intolerance may bring on the condition. Irritable bowel syndrome may also cause diarrhea.
Drinking untreated water that contains the giardia lamblia parasite can also cause diarrhea that develops one to four weeks later.
Since most caused of diarrhea are viral, they will clear up in a few days with good home treatment.
