Is it okay to have children if my blood type is positive?

Patient's question:

My blood type is positive. Do I need to have children? If not, can it be cured? Previous treatment history and effectiveness: I haven't been treated yet. What kind of help do I need: I had my first child, who is quite healthy. When I wanted a second child, I was told that if I have children with my blood type, there might be a risk of having a child with a birth defect again. Can it be cured?

Doctor's answer:

The main symptoms of hemolytic disease recurring are: jaundice. In severe cases, anemia may occur, accompanied by edema. If jaundice and other symptoms spread rapidly, it may indicate a serious condition, and prompt measures should be taken.
Medical Advice: No help. If a newborn experiences recurrent hemolysis, it suggests that their umbilical cord blood also contains a large amount of free antibodies, which offers no benefit in treating the hemolytic condition. For ABO incompatibility-related recurrent hemolysis, the blood used during surgery must be specially prepared—specifically, red blood cells from type O blood and plasma from type AB blood must be mixed.
Lifestyle Management: Hemolytic disease rarely recurs in the firstborn. Therefore, it is recommended that women of childbearing age should view induced abortion with caution. During the pregnancy process, it is also advisable to undergo pre-natal genetic counseling to prevent the hemolytic condition from affecting the baby.
