What is necrotizing enterocolitis?
Necrotizing enterocolitis (NEC) is an intestinal disease. It occurs when tissue in the intestine becomes inflamed and then dies. NEC is most often found in premature, sick, or low-weight newborns. It often begins within 2 weeks of birth when your baby still is in the hospital.
Symptoms of necrotizing enterocolitis
NEC symptoms may begin all of a sudden or over time. Common symptoms include:
- swollen stomach
- stomach pain
- bloody stool
- change in stool amounts or times
- problems feeding or eating
- decreased energy
- changing body temperature
- uneven breathing, heart rate, or blood pressure.
What causes necrotizing enterocolitis?
There is no exact cause for NEC. The main source is intestinal bacteria. If your baby is premature, their immune and digestion systems are weaker. Another trigger could be a decrease in blood or oxygen to the intestine. This can damage tissue and lead to NEC. Full-term babies who have congenital heart disease also can get NEC.
How is necrotizing enterocolitis diagnosed?
Your doctor can diagnose NEC. They will perform a physical exam to check for symptoms. Then, they will take a stomach X-ray. The picture will show if there is inflammation or air in your baby’s intestine. Your doctor also may test your baby’s blood or stool. These tests can reveal the presence of infection or lactic acid. They also can help determine the severity of the condition.
Can necrotizing enterocolitis be prevented or avoided?
It is hard to prevent or avoid NEC. However, there are factors that can increase your baby’s risk for NEC, including:
- premature birth
- blood transfusion
- formula diet instead of breast milk
- exposure to an outbreak.
Necrotizing enterocolitis treatment
A range of options is available to treat NEC. Early on, your doctor will want to rest your baby’s intestine. Instead of normal feedings, they will receive nutrition through an intravenous tube. Antibiotic medicines treat the infection. Your baby may need to use a breathing machine if breathing becomes difficult. Severe cases of NEC may require emergency surgery. This is if the weakened, infected tissue creates a hole in the intestine. The surgeon will remove dead tissue and repair the bowel and intestine.
Living with necrotizing enterocolitis
Babies who have NEC require treatment and ongoing monitoring. NEC can be cured and have little or no lasting effects. However, some babies may have future problems with their intestine or digestive tract. They can have blockage caused by abnormal intestinal tissue or scar tissue. Another problem is called short-gut, or short-bowel, syndrome. There also is a risk of death, especially for premature babies.
