Prognosis Prognosis is variable depending on the severity of the anemia, but as in other chronic hemolytic disorders, gallstones and iron overload may develop, requiring appropriate treatment. [orpha.net]

The prognosis (outlook) after splenectomy is for a normal life and a normal life expectancy. [medicinenet.com]

Treatments and Prognosis for Hemolytic Anemia Doctors who treat hemolytic anemia will first focus on returning the patient's red blood cell count to as close to normal as possible and halting or slowing the destruction of red blood cells. [everydayhealth.com]

Prognosis The prognosis for patients with hemolytic anemia depends on the underlying cause. Overall, mortality rates are low in hemolytic anemias. However, the risk is greater in older patients and patients with cardiovascular impairment. [emedicine.medscape.com]
