Hemolysis generally affects fetal development. Hemolysis is caused by the mismatch between the mother’s blood type and the fetus’s blood type, which may be manifested as jaundice, anemia or edema, etc. In severe cases, kernel jaundice may occur, resulting in neural damage to the fetus’s brain, causing mental retardation, and affecting the fetus’s growth and development. Therefore, hemolysis is still relatively serious, and pregnant women need to pay attention to it. Hemolysis can be treated by medication, blue light irradiation or blood exchange, etc. These treatments need to be given under doctor’s evaluation to avoid adverse conditions. It is recommended that family members should pay attention to checking the antibodies in the body during pregnancy and take pregnancy tests in time. Don’t worry too much, early detection and early treatment to avoid delaying the condition.
