What does hemolysis refer to?

Hemolytic anemia, medically termed as hemolysis, is a type of anemia caused by an abnormally accelerated rate of red blood cell destruction, leading to insufficient compensation by the bone marrow. This phenomenon can be triggered by various factors, including but not limited to maternal-fetal blood group incompatibility, intrinsic defects of red blood cells themselves, and abnormal external environmental or disease-related effects on red blood cells. Depending on the acuteness of onset, hemolytic anemia can be categorized into acute and chronic forms. Acute hemolysis is severe and often accompanied by high fever, jaundice, and other symptoms, whereas chronic hemolysis has a longer course and mainly presents with persistent anemia, jaundice, and splenomegaly. Hemolytic anemia poses particular risks to newborns and infants, necessitating prompt recognition and timely, effective treatment measures.
