Diet and Management of Diarrhea

Diet plays an important role in human health and disease. Of all human diseases, diarrheal illnesses bring diet into sharp focus as it has a direct causal and therapeutic relationship. With the advent and widespread use of next generation sequencing, significant advances have been made in unraveling the etiologies of congenital diarrheas and enteropathies, some of which are eminently treatable with dietary modification. Early institution of appropriate dietary therapy is lifesaving in congenital osmotic diarrheas. Chronic diarrhea in older children and adolescents often have an underlying dietary basis, depending on the etiology. Identification and exclusion of the offending food in the diet results in dramatic improvement in symptoms. It is equally important to be prudent and cautious in the use of exclusion diets in management of chronic diarrhea as it is associated with micronutrient deficiencies, needless escalation of cost and enable maladaptive food intake behaviors. In this review, authors discuss etiology specific dietary management of diarrhea in children with emphasis on congenital diarrheas and enteropathies.
