Necrotizing enterocolitis (NEC) is a serious illness in newborns. It happens when tissue in the large intestine (colon) gets inflamed. This inflammation damages and sometimes kills the tissue in your baby’s colon.
Any newborn can get NEC. But it’s most common in premature babies. It also happens in babies who spend time in newborn intensive care units (NICUs). This condition is more common in babies who weigh less than 3 pounds, 4 ounces (1,500 grams).
No one knows what causes NEC. It may happen if not enough blood and oxygen reach your baby’s intestinal tissues. Then when food moves into the area, bacteria from the food can damage the tender tissues. This can harm the tissues and cause them to die. When this happens, a hole forms in the intestine. This can cause a severe infection in your baby’s belly (abdomen).
Several things may raise your baby’s risk for NEC.
Premature babies are smaller and weaker. This means they may have trouble with blood and oxygen circulation. They also have problems with digestion and fighting infections. This increases their chance of having NEC.
High-risk babies are more likely to get NEC. A high-risk baby is often one who is premature. Premature babies are often fed formula through bottles or tubes. Babies who are breastfed are less likely to get NEC.
Babies who had a difficult birth or low oxygen levels at birth are more likely to get NEC. When there is too little oxygen, the body sends blood and oxygen to the brain and heart first. This reduces the blood flow to the intestinal tract. This can cause less oxygen in blood to reach the colon.
Babies with too many red blood cells have a higher risk for NEC.
Babies with infections in their intestines are more likely to get NEC.
Each child may experience symptoms differently. Symptoms usually show up in the first 2 weeks of life. They may include:
Signs of infection include:
The symptoms of NEC may be similar to symptoms of other conditions. Make sure your child sees his or her healthcare provider for a diagnosis.
Your baby’s healthcare provider will check him or her for signs of NEC.
Your child may need an abdominal X-ray. An X-ray can show if your child’s intestine has a bubbly appearance. It can also show signs of air or gas in the large veins of your child’s liver. Air may also be on the outside of the intestines in your child’s belly (abdomen).
Your child’s healthcare provider may also put a needle into his or her abdominal cavity. This is to look for intestinal fluid in your child’s abdomen. This is a sign of a hole in the intestines.
Treatment will depend on your child’s symptoms, age, and general health. It will also depend on how severe the condition is. Treatment may include:
If your baby has severe NEC, he or she may need:
NEC can cause a hole to form in your baby’s intestines. This makes bacteria in the intestinal tract leak out into your child’s abdomen. This causes an infection. This can harm a small or large part of the intestine. It can happen quickly.
An infection in the intestines is hard for a baby to fight. Even with treatment, there may be serious problems. Some of these issues include:
