During pregnancy, the mother and the unborn child share a strong connection. However, there are situations in which fetal blood incompatibility can lead to complications, putting the pregnancy at risk.

Fetal blood incompatibility occurs when the mother’s immune system detects foreign substances from the baby and responds to them by producing antibodies that attack the baby’s blood cells. This condition is also known as Rh disease. In severe cases, it can lead to anemia, jaundice, brain damage, stillbirth, or even death. Below are some of the complications that can arise from fetal blood incompatibility during pregnancy.

1. Hemolytic Disease of the Newborn (HDN)

Hemolytic disease of the newborn (HDN) is one of the complications that can result from fetal blood incompatibility. It develops when the baby’s red blood cells are destroyed by the mother’s antibodies, leading to anemia.

HDN can cause fatigue, lethargy, poor feeding, pale skin, and a rapid heart rate in newborns. In severe cases, the baby may require a blood transfusion to reverse the effects of HDN.

2. Jaundice

Jaundice is another complication that can result from fetal blood incompatibility.

It is a condition in which the baby’s skin and whites of the eyes take on a yellowish hue due to a buildup of bilirubin, a substance that results from the breakdown of red blood cells. Jaundice can lead to lethargy, poor feeding, and dehydration in newborns. In severe cases, it can cause brain damage if not treated promptly.

3. Brain Damage

In rare cases, fetal blood incompatibility can lead to brain damage. This can happen when the baby’s brain is deprived of oxygen due to severe anemia or when the baby develops kernicterus, a rare form of brain damage caused by severe jaundice.

Kernicterus can cause hearing loss, cerebral palsy, developmental delays, and other long-term complications that can affect the child’s quality of life.

4. Stillbirth

In very rare cases, fetal blood incompatibility can lead to stillbirth. This occurs when the baby dies in the uterus after 20 weeks of pregnancy. Stillbirth can result from severe anemia, brain damage, or heart failure.

5. Preterm Labor

Fetal blood incompatibility can also increase the risk of preterm labor. Preterm labor is when the mother goes into labor before 37 weeks of pregnancy.

Preterm labor can lead to premature birth, which can cause complications such as respiratory distress syndrome, developmental delays, and low birth weight.

6. Hydrops Fetalis

Hydrops fetalis is a condition in which the baby accumulates too much fluid in the body due to severe anemia. Hydrops fetalis can cause swelling in the baby’s body, liver, and spleen, making it difficult for the baby to breathe.

In severe cases, hydrops fetalis can lead to stillbirth or death shortly after birth.

7. Delayed Growth

Fetal blood incompatibility can slow down the baby’s growth in the uterus, leading to premature birth or low birth weight.

Low birth weight babies are at risk of developing complications such as respiratory distress syndrome, infections, and developmental delays.

8. Trauma During Birth

Babies born with fetal blood incompatibility are at a higher risk of suffering trauma during birth due to their fragile health status.

Trauma during birth can include birth injuries such as shoulder dystocia, brachial plexus injuries, or cerebral palsy.

9. Reoccurrence of Fetal Blood Incompatibility in Future Pregnancies

If a woman has had a previous pregnancy with fetal blood incompatibility, there is an increased risk of blood incompatibility in future pregnancies.

Women who have had Rh disease or other forms of fetal blood incompatibility may require special treatment during subsequent pregnancies to minimize the risk of complications.

10. Emotional Distress

Fetal blood incompatibility can cause emotional distress to the parents. The risk of complications from fetal blood incompatibility can cause anxiety and stress to the parents, especially if the pregnancy is considered high-risk.

The emotional distress can also stem from fears of losing the baby or concerns about the baby’s long-term health effects.
