Aetiology
Anaemia can be caused basically in one of three ways, secondary to decreased erythropoiesis, increased haemolysis or secondary to blood loss
Decreased production
Deficiency of erythropoetic agents; iron, vit B12, folic acid, vit C, thyroxine, copper
Inadequate production - renal failure
Hypoplastic or aplastic
Haemolytic
Excessive red cell breakdown -- haemolysis
May be raised serum bilirubin
May be caused by any haemolytic disease
Blood loss
Any cause of chronic haemorrhage
