OverviewDiarrhea is a condition in which loose, watery stools are passed more often than normal.
What is going on in the body?Diarrhea occurs when the colon or large intestine becomes irritated. This can be caused by many things, including infection, chemical toxins, inflammation, stress, or anxiety. The colon responds to this irritation in these ways:
• The amount of water and mucus in the stool is increased.
• The amount of water the colon reabsorbs from the stool is decreased.
• The intestine empties the stools from the body more often.
What are the signs and symptoms of the condition?The key symptom of diarrhea is frequent bouts of loose, watery stools. Abdominal pain and cramping often occur as well. The person may have loss of appetite, nausea, and vomiting. Stools that contain blood or pus may be a sign of a more serious health problem.
What are the causes and risks of the condition?
Viruses cause most episodes of diarrhea in the U.S.
What can be done to prevent the condition?
Frequent hand-washing with soap and warm water is the best way to prevent diarrhea. This is especially important if a person has been exposed to anyone who has diarrhea or has used a public restroom.
How is the condition diagnosed?
Diagnosis of diarrhea begins with a medical history and physical exam. If there is severe pain or blood in the stool, a healthcare professional will generally examine the abdomen.
