Causes of Nutritional Decline During Diarrhea


According to WHO (1980), diarrhea is loose, watery stools more than 3 times daily. Diarrhea is divided into two based on the origin and duration, ie acute and chronic diarrhea (Mansjoer, A.1999,501).

Diarrhea is a disease syndrome that is characterized by changes in the shape and consistency of stool slow to melt and increased frequency of bowel movements is usually 3 times or more a day. Diarrheal disease is the No. 2 cause of morbidity and mortality in children, especially among children under 5 years of age.
Various factors affect the incidence of diarrhea , such as environmental factors, nutrition, population, education, socio-economic circumstances and behavior.


Causes of Nutritional Decline During Diarrhea

1. Reduced food intake, is a result of:
  • Anorexia is primarily seen in children with dysentery.
  • Vomiting.
  • Stopping food because of traditional beliefs to rest the bowel.
  • Providing food with less nutritional value, such as soup diluted.
2. Decreased absorption of nutrients, Caused by :
  • Epithelial damage absorption which reduces the surface area of the intestine.
  • Disaccharide deficiency because of the failure of enzyme production by the damaged microvilli.
  • Reduced concentration of bile acids necessary for the absorption of fat.
  • Transit of food through the gut very quickly lead to not enough time for digestion and absorption.
3. Increased need for nutrients, nutrient requirement increases due to :
  • Metabolic demand due to heat.
  • The need to improve the intestinal epithelium.
  • The need to replace the loss of serum proteins through the damaged intestinal mucosa as in dysentery.
