Heinz body anemia can present with symptoms including jaundice, dyspnea, tachycardia, hematuria, fatigue, and even hypotension. Heinz bodies are inclusions of irreversibly denatured hemoglobin attached to the erythrocyte cell membrane. They are indicative of oxidative injury to the erythrocyte. Oxidative damage may be incurred by external substances or due to hereditary enzyme or hemoglobin defects. It has been reported that congenital Heinz body hemolytic anemia is caused by unstable hemoglobins such as Hb Bristol, Hb Wien, Hb Toyama, and Hb Bibba.
