Anemia is a low level of red blood cells (RBCs). These cells pick up oxygen in the lungs and bring it to the rest of the body. Low levels make it hard for the body to get enough oxygen.
Anemia of prematurity is when this problem happens in babies who are born too early.
Anemia of prematurity may be caused by 1 or more of the these problems:
Infants are likely to get anemia because:
Things that may raise the risk of this problem are:
Mild anemia may have no symptoms. Moderate or severe anemia may cause:
You will be asked about your baby’s symptoms and health history. A physical exam will be done.
Your baby's blood will be tested. This can be done with blood tests.
A diagnosis will be made based on the blood test. The test results may also help find the cause of the anemia.
Treatment will depend on the cause of anemia. Mild anemia may be monitored with blood tests. As little blood as possible will be taken to keep the anemia from getting worse.
Treatment options are:
Nutrition can help with recovery by helping the body make more RBCs.
Iron is important in making RBCs. Some babies may be given supplemental iron.
Some babies with severe problems may need treatment right away. A blood transfusion can quickly raise the level of RBCs. It may need to be done more than 1 time.
