Red blood cells and oxygen-carrying hemoglobin are needed for the blood to function properly. Fetal anemia can cause a variety of side effects. Next we are telling you about this condition occurring in the fetus.
First understand fetal anemia
Fetal anemia occurs when red blood cells are not being produced in sufficient quantities or are being destroyed more rapidly than they are produced. Red blood cells contain hemoglobin which carries oxygen throughout the body.
Adequate amounts of oxygen are needed to nourish the cells and organs of the unborn baby.
Fetal anemia can cause a baby’s heart to beat too fast. At this time, the heart has to work harder to make more blood and oxygen throughout the body.
In some severe cases, heart failure can occur. If left untreated, fetal anemia can be life-threatening.

due to fetal anemia
Fetal anemia occurs when the blood types of the mother and the child do not match. Most cases are seen in Rh incompatibility, where the mother’s blood type is Rh negative while the baby is Rh positive.
The mother’s immune system starts attacking the baby’s Rh-positive red blood cells, mistaking them for an external threat. To fight this, the immune system makes antibodies that reach the baby through the placenta and attach to its red blood cells.
Now the baby’s immune system starts fighting these antibodies. In this vertigo, many red blood cells of the child are destroyed.
Fetal anemia can also be caused by a mother-to-child infection, such as parvovirus B19, before delivery.
Fetal anemia treatment
Women whose red blood cell antibodies test positive and whose children are at risk of anemia, they are regularly examined to find out how many antibodies are being made in the mother’s body.
When the antibodies in the mother’s blood reach critical levels, a high-resolution ultrasound may be recommended to detect anemia in the baby.

what do doctors do
If the baby has mild fetal anemia, then this condition needs to be monitored carefully during pregnancy. On the other hand, if the condition is serious, then the child may need to be transfused blood once or several times in the womb itself. During this procedure, red blood cells are injected through the vein of the umbilical cord.
