Necrotizing enterocolitis is the death of tissue in the intestine. It occurs most often in premature or sick babies.
Necrotizing enterocolitis occurs when the lining of the intestinal wall dies and the tissue falls off. The exact cause of this disorder is unknown. It is thought, however, that a drop in blood flow to the bowel keeps the bowel from producing mucus. The mucus protects the gastrointestinal tract. Bacteria in the intestine may also be a cause.
Most of the time, this problem develops in an infant that is ill or premature. It is likely to occur while the infant is still in the hospital.
Babies at higher risk of the condition include:
Infants who are fed concentrated formulas
Infants in a nursery where an outbreak has occurred
Infants who have received blood exchange transfusions
Symptoms may come on slowly or suddenly, and may include:
Get emergency medical care if any symptoms of necrotizing enterocolitis develop. Infants that have been hospitalized for illness or prematurity are at higher risk and should be watched for this problem.
