Hemolytic anemia is a type of blood disorder that occurs when the body's red blood cells (RBCs) are destroyed faster than they can be produced. Hemolysis is the medical term for the destruction of red blood cells. Hemolytic anemia is classified according to the site of hemolysis, which is either extravascular or intravascular.
Intravascular Hemolysis
Intravascular hemolysis is the destruction of red blood cells within the blood vessels. This type of hemolytic anemia is caused by different conditions, such as autoimmune disorders, drugs, toxins, and infections. Autoimmune hemolytic anemia is the most common type of intravascular hemolysis. In this condition, the body's immune system mistakenly attacks and destroys its own red blood cells.
Extravascular Hemolysis
Extravascular hemolysis is the destruction of red blood cells outside the blood vessels. It is usually caused by mechanical damage to the cells, such as when the red blood cells are forced through very small capillaries or when the cells are damaged by a trauma. Extravascular hemolysis can also be caused by certain medications, toxins, and infections.
