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.


  • 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)

Epidemiology and Demographics

  • In 2017, 8% of all deaths in children all over the world were due to diarrhea. [6] [7]
  • 2-3 million deaths per year occur every year due to acute diarrhea especially in developing countries.
  • 9% of all hospitalizations in the United States under the age of 5 are due to diarrhea.
  • In the age group of fewer than 3 years, the incidence of diarrhea is noted to be 1.3-2.3 episodes per child annually.


  • In one study conducted in Hanoi, Vietnam on children <5 years of age with diarrhea; it was found that 40.9% were 1 year and below and 71.0% were 2 years and below.



  • Female gender has a lower risk of diarrheal disease. [9]

Risk Factors

  • Travel to countries with poor sanitary conditions, swimming, daycare, sick contacts at home and school, antibiotics usage. Autoimmune conditions such as celiac and inflammatory bowel disease. [4]

Natural History, Complications and Prognosis

  • Moderate to severe diarrhea can cause dehydration in children. Severe dehydration can cause seizures, dizziness, lack of energy, dry skin, etc. [10]
  • Usually prognosis is good, and most cases resolve in a few days.


Diagnostic Criteria

  • The diagnosis of diarrhea is made when either the frequency of bowel movements increases or the consistency of stools becomes looser than what is normal for that child. [4]


Signs and symptoms that indicate severe disease: [11]

Physical Examination

  • Patients with severe diarrhea usually appear toxic.
  • Physical examination may be remarkable for: [12] [13]

Laboratory Findings

  • Measurement of serum bicarbonate concentration of more than 15mEq per L is the laboratory finding used to evaluate 5% or less dehydration. Hypernatremic dehydration can be confirmed by serum sodium levels. [11] [4]
  • If there is evidence of blood or mucus in stool, or if the patient is immunocompromised, then stool microbiological tests can be done. They are, however, not required in suspected viral cases.
  • Stool culture results can sometimes become available only after 3-5 days, in some infectious causes, the organism is not visible even on stool testing.


There are no ECG findings associated with diarrhea.


  • Usually not indicated but may be done to rule out structural anomalies of the digestive tract. [14]

Echocardiography or Ultrasound

  • Severe dehydration in children caused by acute diarrhea can be measured by ultrasound evaluation of the ratio of aorta/inferior vena cava. [15]

CT scan

There are no CT scan findings associated with diarrhea in children.


There are no MRI findings associated with diarrhea in children.

Other Imaging Findings

There are no other imaging findings associated with diarrhea.

Other Diagnostic Studies


Medical Therapy

  • Fluids to prevent dehydration, especially in babies under six months of age. Artificially sweetened drinks like fruit juices should be avoided as these can make it worse.
  • Slow initiation of rehydration drinks which have a perfect mix of water and electrolytes. Feed normally, medications are usually not required. [16]


  • Mainstay is the maintenance of sanitary conditions. Caregivers should wash their own hands and encourage children to do so after changing diapers, before and after handling food, after having contact with pets, after spending time in the garden/ soil. [16]
