P55: Haemolytic disease of fetus and newborn
P55.9: Haemolytic disease of fetus and newborn, unspecified
Blood is made up of a liquid part and different blood cells, among other things. The blood cells include the red blood cells, the white blood cells and the platelets. The red blood cells carry oxygen from the lungs throughout the body. Red blood cells contain the red hemoglobin that gives blood its color. This pigment is important for carrying oxygen in the blood.
There can be different reasons why the red blood cells are increasingly being broken down. For example, antibodies may be damaging the child's red blood cells. It may also be that the red blood cells have changed, and that is why they are being broken down in the body. Also, if the child has been infected by certain pathogens in the womb, red blood cells may increasingly be broken down.
If red blood cells are increasingly being broken down, the child may have too little red blood pigment. The child may then have a variety of indications. Its eyes or skin may turn yellowish due to by-products. Breathing problems or a fast heartbeat may also occur when there is not enough red blood pigment.
