- Diarrhea is a common problem that usually lasts a few days and
typically does not require treatment.
- Diarrhea can become life-threatening when it causes severe
dehydration.
- Different processes in the body may promote diarrhea, including
a failure of the intestines to absorb adequate nutrients and fluids
during digestion, the release of too much fluid into the digestive
tract or complications as the result of intestinal disorders.
- Diarrhea can be short-term or long-term, with each type ranging
widely in severity.
- Acute diarrhea can be defined as lasting less than four weeks,
chronic diarrhea as lasting more than four weeks.
- The most common cause of acute diarrhea is a viral infection or
bacteria or parasites consumed through contaminated food or
water.
- Chronic diarrhea may indicate a more serious problem, such as
irritable bowel syndrome or inflammatory bowel disease.
- Diarrhea can also be a side effect of many medications,
especially antibiotics.

also cause diarrhea.

options will depend on what is causing the diarrhea.

untreated and resolves itself within a few days.

parasites, antibiotics may be required to treat the
infection.

diarrhea.

electrolytes will need to be replaced.

diarrhea.

their episodes with dietary changes.

foods and drink only bottled water to avoid contaminated food or
water that may cause diarrhea.
