Functional Diarrhea in Children

Functional diarrhea in children is a disease that has been focused on by both general pediatricians as well as pediatric gastroenterologists across the world. Although it is seen across the pediatric age group from late infancy to adolescence, most still believe that functional diarrhea only occurs in younger children. Recent epidemiological studies have shown that functional diarrhea is prevalent in all subcontinents. The classic clinical features include chronic loose stools with undigested food particles without growth faltering. Although known for long years, pathophysiological mechanisms and therapeutic options are not well explored, and the existing literature is outdated. In this article, authors review the available literature on functional diarrhea, with a reminder that a fresh look is needed to broaden the horizons of understanding of this disease.
