Key points
- Anemia is a deficiency of red blood cells.
- In premature babies, anemia can be caused by slower red blood cell production than in full-term babies, and frequent blood tests.
- Severe anemia is usually treated with blood transfusions, and may also require EPO injections and iron supplements.
Why is jaundice common in premature babies?
Jaundice, a sign of elevated bilirubin levels, is common during the first weeks of life, especially among preterm newborns. Bilirubin, a product from the normal breakdown of red blood cells, is elevated in newborns for several reasons: Newborns have a higher rate of bilirubin production due to the shorter lifespan of red blood cells and higher red blood cell concentration compared to adults.
Can anemia during pregnancy harm the fetus?
When this happens to a growing baby during pregnancy, it is called fetal anemia. Fetal anemia can range from mild to serious and may cause many complications. In severe cases, the baby’s heart tries to compensate for the lack of red blood cells by pumping extra hard, which can lead to fetal heart failure.
What are the causes of a premature baby?
The causes of prematurity
- The use of toxic substances. For example, tobacco, cocaine, or amphetamines.
- Uterine factors. Uterine surgery, malformations, or fibroids influence prematurity.
- Complications of the current pregnancy. Bleeding in the 2nd and 3rd trimester, alterations in amniotic fluid volume, premature rupture of membranes, etc.

Why are premature babies at risk of Anaemia?
Preterm infants are prone to develop iron deficiency anemia (IDA) in the first 4 months of life due to lower iron stores at birth compared with term infants, rapid growth and iron losses.
Is it common for premature babies to be anemic?
All babies have some anemia when they are born. This is normal. But in premature babies, the number of red blood cells may decrease faster and go lower than in full-term babies.
Which is the most common cause of anemia in preterm newborns?
CAUSES OF NEONATAL ANEMIA: 1. Blood loss, the commonest cause of neonatal anemia, including: A. Obstetrical causes: placental abruption, placenta previa, trauma to placenta or umbilical cord during delivery and rupture of anomalous placental vessels B.
When does prematurity become anemia?
The nadir of the hemoglobin level is typically observed 4-10 weeks after birth in the tiniest infants, with concentrations of 8-10 g/dL if birthweight was 1200-1400 grams, or 6-9 g/dL at birth weights of less than 1200 grams.
How common are blood transfusions in premature babies?
Overall since the 1990s to date it has been reported that up to 90% of extremely low birth weight (ELBW) infants and 58% of preterm infants < 32 weeks of gestational age receive red blood cell transfusions (RBCT) [2-4], mainly due to iatrogenic phlebotomy losses and ventilatory requirements.
Why do prem babies need blood transfusions?
Premature babies may have a lack of red blood cells (anemia) because they're not yet ready to make their own. Full-term babies don't start making their own blood cells for 1 to 3 months. The blood for the transfusion comes from a donor blood bank, just like the blood given to adults.
Why do premature babies need iron supplements?
Preterm infants are at risk for both iron deficiency and iron overload. The role of iron in multiple organ functions suggests that iron supplementation is essential for the preterm infant.
Why are preemies so red?
Extremely red skin This is a common trait of premature babies — especially those born before 34 weeks. The skin appears red because it's actually translucent. Since the skin hasn't been able to fully develop, it's extremely sensitive. Extremely red skin in premature babies is normal.
What happens if baby is anemic?
Anemia results when there's not enough hemoglobin in the red blood cells, or when there are not enough healthy red blood cells, to transport oxygen throughout the body. This can cause problems with cell function and growth.

Pregnant women with folate deficiency anemia can be more likely to have complications, such as premature birth.Heart problems. ... Death.
Why are infants more likely to get anemia?
Infants are likely to get anemia because: Fewer RBCs are made in newborns right after birth. Blood volume cannot keep up with a baby’s growth. RBCs have a shorter lifespan in infants. Things that may raise the risk of this problem are: Family history of anemia. Problems during delivery. Blood loss during birth.
How to prevent anemia of prematurity?
To lower a child’s chance of getting anemia of prematurity: Get proper prenatal care throughout pregnancy. Mothers should take steps to prevent premature birth: Avoid alcohol, smoking, and drugs. Eat a healthy, balanced diet with plenty of fruits and vegetables. Manage chronic health problems.
Why are RBCs low?
Low production of RBCs due to: Nutrition problems. Infections such as rubella or parvovirus that affect the bone marrow where RBCs are made. Destruction of RBCs from health problems like: Incompatibility between mother’s and baby’s blood— Rh incompatibility. Hereditary disorders.
What is the diagnosis of anemia in a baby?
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.
How to treat mild anemia?

What happens to preterm infants?
Preterm infants are often anemic and typically experience heavy blood losses from frequent laboratory testing in the first few weeks of life. Although their anemia is multifactorial, repeated blood sampling and reduced erythropoiesis with extremely low serum levels of erythropoietin (EPO) are major causative factors.
What happens to a newborn when they have low birth weight?

What is AOP in pediatrics?
Pediatrics. Anemia of prematurity (AOP) refers to a form of anemia affecting preterm infants with decreased hematocrit. AOP is a normochronic, normocytic hypoproliferative anemia. The primary mechanism of AOP is a decrease in erythropoietin (EPO), a red blood cell growth factor.
How many times a week does a baby receive a r-epo?
All r-EPO treated infants received 400 U/g three times a week until they reached 35 weeks gestational age. The use of r-EPO did not decrease the average number of transfusions in the infants born at less than 1000 g, or the percentage of infants in the 1000 to 1250 group.
How long before a blood transfusion can you see anemia?
Infants were checked for clinical symptoms and laboratory signs of anemia 24 hours before and after the blood transfusion. The study found that groups 2 and 3 who had significant amount of blood loss, showed poor weight gain, pallor and distended abdomen. These reactions are the most frequent symptoms of anemia in very low birth weight infants.
How much hemoglobin is normal for a term infant?
Healthy term infants Hb rarely falls below 9 g/dL at an age of approximately 10–12 weeks, while in premature infants, even in those without complicating illnesses, the mean Hb falls to approximately 8g/dL in infants of 1.0-1.5 kg birth weight and to 7g/dL in infants <1.0 kg. Because this postnatal drop in hemoglobin level is universal ...
Does anemia decrease hemoglobin?
As anemia develops, there is even more of a significant reduction in the concentration of hemoglobin.

What happens if a baby has a blood type rh negative?
Sometimes the difference between blood groups of a baby and its mother may lead to the presence of maternal antibodies in the baby and premature destruction of its red cells. That often occurs when the mother has blood type Rh-negative, and the baby is Rh-positive; or when the mother is “O” and the baby is “A” or “B.” Blood incompatibilities may lead not only to severe anemia but also to life-threatening newborn jaundice. I wrote separate articles on both topics, and you can find them here: ABO-incompatibility, and RH-incompatibility. Of note, some other blood incompatibilities between mother and her baby also can lead to anemias and jaundice, but they are rarer and of lesser importance.
What are the causes of anemia?
Congenital disorders rarely cause anemia; nevertheless, they are possible. Lets at least look at three different categories of inheritable defects leading to anemia: 1 Membranes defects – those are diseases in which due to structural defects in the wall of red cells, they become misshaped and consequently more prone to premature destruction. Examples are spherocytosis and ovalocytosis. 2 Metabolic defect – due to enzymatic defect, red cells’ life span is shortened. G6PD-deficiency or pyruvate kinase deficiency are examples. 3 Hemoglobinopathies – hemoglobin is an essential protein component of red cells; therefore, congenital defects in its structure can contribute to anemias. Thalassemias and sickle cell anemias are examples of these diseases; however, sickle cell anemia does not affect newborn babies.
Why do you need a blood transfusion for anemia?
Acute anemia due to blood loss during birth leading to low blood pressure frequently will require an urgent blood transfusion. Criteria for a blood transfusion in chronic anemias will vary. They will depend on a baby’s age and general condition, including how much supplementary oxygen for breathing baby needs.
Why do premature babies have anemia?
Most of the time, anemia in a premature baby is due to acute blood loss at birth, iatrogenic chronic blood loss for lab testing, blood group incompatibilities, and suppressed bone marrow due to prematurity or nutritional deficiency.
How does anemia affect a baby?
When a baby develops anemia slowly over time, they usually get better adapted to it. Initially, symptoms may not be obvious, but with time they will become more apparent. A baby may appear pale, have slow feedings, and get more tired with feedings, develop more frequent apneas, and a faster resting heart rate.
What is anemia in medical terms?
We define anemia as having an abnormally low number of healthy red blood cells responsible for carrying oxygen to our tissues. Depending on each patient’s age, what is normal, and what is abnormal number will differ.
Why do we need immunoglobulin?
The immunoglobulin role would be to stop the process in which maternal antibodies keep destroying red blood cells in the baby. Immunoglobulin will not cause an increase in the number of red cells; it only will stop further destruction of them. The baby still may need a supplementary blood transfusion.
What does anemia mean for babies?
Babies who have anemia have a red blood cell count that is lower than normal. Red blood cells carry oxygen throughout the body.
Why does my baby not produce enough red blood cells?
This is known as physiologic anemia. The reason this anemia occurs is that baby’s body is growing fast and it takes time for red blood cell production to catch up.
What is it called when a baby is born prematurely?
The baby is born premature. Babies who are born premature (early) have lower number of red blood cells. These red blood cells also have a shorter life span when compared to the red blood cells of full term babies. This is called anemia of prematurity.
How to diagnose anemia?
Anemia is diagnosed with a blood test by your healthcare provider. Tests that are used to help diagnose anemia include measurements of the following: 1 Hemoglobin: The protein in red blood cells that carries oxygen. 2 Hematocrit: The percentage of blood that is made up of red blood cells. 3 Reticulocytes: The percentage of immature red blood cells in the blood. This is a measure of how many new cells are being created.

Why does my baby's skin turn yellow?
These babies usually have jaundice (hyperbilirubenemia), which can cause their skin to turn yellow. In a few babies, anemia can also be caused by infections or genetic (inherited) disorders. The baby loses too much blood.
Do babies with anemia need blood transfusions?
Many babies with anemia do not need any treatment. However, very premature babies or babies who are very sick may need a blood transfusion to increase the number of red blood cells in the body. Other babies will be treated with medicine to help their bodies make more red blood cells.
What Is Anemia?
To help explain anemia, let's begin with a little background on blood cells. Blood is made up of different kinds of cells, almost half of which are red blood cells. These cells contain a red pigmented protein called hemoglobin. The job of hemoglobin is to carry oxygen to tissues in the body and carry away carbon dioxide, which is a waste material. Anemia results when there’s not enough hemoglobin in the red blood cells, or when there are not enough healthy red blood cells, to transport oxygen throughout the body. This can cause problems with cell function and growth.
What Is the Treatment for Anemia in Babies?
To treat your baby’s anemia, the healthcare provider may recommend medications, dietary restrictions, or supplements. If the anemia is due to a lack of iron, the provider may prescribe a medication for iron in liquid drop form. The provider may want to see your baby periodically to check her iron levels. It's important that she’s getting just the right amount of iron supplementation and not too much. Do not stop giving your baby the iron medicine unless your provider has told you it’s no longer needed. If it’s determined that your baby’s anemia is due to a blood cell disorder like hemolytic anemia, sickle cell anemia, or thalassemia, your baby’s provider may recommend you take your baby to a hematologist, a doctor who specializes in blood conditions. If your newborn was born prematurely or if your baby is very ill, in some cases your little one’s healthcare provider may recommend a blood transfusion to treat the anemia.
What is anemia in babies?
Anemia is a condition that results when the body doesn't have enough healthy red blood cells, which are responsible for carrying oxygen to the body’s tissues. Anemia may occur in newborns and in older babies, and can affect older children and adults too. Your little one could be anemic for a number of reasons.
Why do babies drink cow's milk?
This is frequently due to an iron deficiency, which can occur when young babies start drinking cow's milk too early (cow's milk has very little iron, and should not be introduced before the age of 1). In rare cases another nutritional deficiency could be the issue, such as a lack of folic acid.
What to do if your baby is formula fed?
If your baby is formula-fed, choose a baby formula that has added iron. Avoid low-iron formula.
What is the function of blood cells?
These cells contain a red pigmented protein called hemoglobin. The job of hemoglobin is to carry oxygen to tissues in the body and carry away carbon dioxide, which is a waste material. Anemia results when there’s not enough hemoglobin in the red blood cells, ...
