Overview

If left untreated, patients with Acute diarrhea may progress to develop symptoms of fluid depletion including altered consciousness, electrolyte imbalance, dehydration, metabolic acidosis and malnutrition. Common complications of acute diarrhea include confusion, convulsions, sepsis, and death. Prognosis is generally good when the underlying cause is identified and treated early.


Natural History

  • If left untreated, the patient with Acute diarrhea will develop symptoms and signs of dehydration (dry mouth and tongue, sunken eyes, confusion, lethargy, poor skin turgor, delayed capillary refill), electrolyte imbalance, metabolic acidosis and eventually the patient will deveop hypovolemic shock, coma or death.

Complications

Prognosis

Acute diarrhea is usually self limiting and has good prognosis when the underlying cause is identified and treated. The presence of these features in a patient with acute diarrhea over 2 weeks may indicate poor prognosis. [1] [2]
