Definition of Necrotizing enterocolitis:

Necrotizing enterocolitis is the death of intestinal tissue. It most often affects premature or sick babies.

Causes, incidence, and risk factors:

Necrotizing enterocolitis occurs when the lining of the intestinal wall dies and the tissue falls off. The cause for this disorder is unknown. However, it is thought that a decrease in blood flow to the bowel keeps the bowel from producing mucus that protects the gastrointestinal tract. Bacteria in the intestine may also be a cause.

This disorder usually develops in an infant that is already ill or premature, and most often develops while the infant is still in the hospital.

Those with a higher risk for this condition include:

• Premature infants
• Infants who are fed concentrated formulas
• Infants in a nursery where an outbreak has occurred
• Infants who have received blood exchange transfusions
