Diarrhea defines as an increase in frequency or change in consistency of stool to become more liquid; which is different than normal for that person is called [[diarrhea]]. [[Causes]] include [[infections]], diet intolerance, malnutrition, etc. Diarrhea is usually self-limited. Severe cases of dehydration may require treatment.

Synonyms and keywords: Diarrhea in kids

Overview

Diarrhea defines as an increase in frequency or change in consistency of stool to become more liquid; which is different than normal for that person is called diarrhea. Causes include infections, diet intolerance, malnutrition, etc. Diarrhea is usually self-limited. Severe cases of dehydration may require treatment.

Historical Perspective

  • Hippocrates first coined the term diarrhea which was derived from the Greek word "diarrhoia", which translates into "flowing through".[1]
  • It was described as a symptom of a lot of conditions such as intestinal parasites, cholera, and in relation to improper water and food handling.

Classification

  • Chronic diarrhea in children may be classified according to the following subtypes/groups:[2]
  • Osmotic: due to unabsorbed nutrients
  • Secretory: due to imbalances in ion secretion
  • Mixed: stool osmotic gap (50-100 mOsm)

Pathophysiology

Causes

Other Diagnostic Studies

Treatment

Medical Therapy
