2. Is mother-child blood group incompatibility dangerous?
When ABO blood group incompatibility occurs, the co-antibody in the dominant mother's blood group O can cross the placenta and cause hemolysis in utero.
When there is a case of Rh blood group incompatibility, for the first time in pregnancy, most babies are born healthy and normal because at this time the Rh blood group incompatibility has not yet affected. However, when the mother's blood comes in contact with the baby's blood during labor, the production of antibodies against the Rh factor begins. Or during pregnancy, if the mother has an injury, bleeding in the abdomen, then the blood of the mother and the fetus mix, the mother's body is stimulated to produce anti-Rh antibodies, causing miscarriage.
Incompatibility with mother and child Rh blood group will be more dangerous for the next pregnancy. Once the mother's body has made antibodies against the Rh factor in her baby's blood, if the baby has Rh(+) blood, the mother's body continues to produce large amounts of antibodies that can cross the placenta and affect the baby. to the fetal red blood cells, causing hemolytic anemia in the newborn. This disease causes babies to be born with jaundice, which in severe cases can lead to liver or heart failure.
