Congenital glucose-galactose malabsorption: A rare cause of chronic diarrhea

Diarrhea present initially at early neonatal period is rare and is generally caused by congenital malabsorptive disorders. Congenital glucose-galactose malabsorption (CGGM) is a rare autosomal recessive disorder present as a protracted diarrhea in early neonatal life. A 3 month-old female infant present with chronic diarrhea, severe failure to thrive, hypernatraemic dehydration and nephrocalcinosis was studied. Early onset diarrhea in a patient with consaguionus parents should alert the pediatricians to think about a rare congenital cause of chronic diarrhea that can present with a life threatening condition.
