Diarrhea education
What is diarrhea?
Diarrhea is defined as the passage of three or more loose or liquid stools per day, or when your passage is much more frequent than normal.
Your body's natural defense
Diarrhea is often caused by your body's natural reaction to something unwanted in your gut. This reaction can be triggered by a range of different microorganisms which are often spread via contaminated food and drinking water or human contact. During a bout of diarrhea, your immune system is working to flush out the unwanted intruder and regain balance in your gut.
Certain foods and medications can also cause a similar immune reaction. For example, individuals allergic to certain foods may experience diarrhea after eating those foods, as the body works to rid itself of the unwanted allergens.
What are the symptoms of diarrhea?
The most common symptoms include:
Loose, watery stools
Urgent need to have a bowel movement
Abdominal cramping / pain
Fever
Blood in the stool
Bloating
Nausea
How long should diarrhea last?
While most cases clear up within a few days, if your diarrhea lasts more than three days, you could be at risk for dehydration. In the process of protecting itself, your body rids itself of more than just the problem-causing intruder. Important fluids and electrolytes are also flushed from your system, which can lead to dehydration.
Diarrhea and the subsequent dehydration can be quite dangerous in children (especially babies), so call your pediatrician if your child's symptoms persist beyond one day.
While diarrhea typically resolves itself in a few days, drugs such as loperamide may prolong a bout of diarrhea as they work by slowing your body's natural flushing process and can potentially keep the problem-causing intruder in your gut longer.
