Congenital short-bowel syndrome, a condition in which a portion of the small intestine is absent or not functioning properly leading to decreased absorption of both fluids and nutrients. Congenital lactase deficiency, a condition caused by a genetic mutation in which the body cannot digest lactose properly. Glucose-galactose malabsorption, a genetic disorder caused by changes in a protein critical for the transport of glucose and galactose across the intestine which leads to impaired glucose/galactose absorption, dehydration, and severe diarrhea in young children. Typically, the severe diarrhea improves with a diet low in glucose/galactose and the tolerability to glucose/galactose improves with age. Hirschsprungs disease (HSCR), a gut motility disorder characterized by a lack of nerve cells in the large intestine which are needed to move the stool through the digestive tract. In infants, HSCR typically presents when a newborn is unable to pass the first feces, or meconium within 48 hours of birth. Other symptoms include blockage of the intestine, fever, rapid release of stool and flatulence upon rectal examination, and may present with diarrhea in infants. Intestinal pseudo-obstruction (IPO), a gut motility disorder characterized by the inability to contract intestinal walls with symptoms similar to intestinal obstruction but lack a distinguishable cause of obstruction. Signs and symptoms include abdominal pain, dilated or enlarged bowel, constipation and may include diarrhea. Although rare in infants, IPO is a type of congenital disorder that may present with diarrhea in infants.
