Get a blood transfusion
If you have severe iron deficiency, you might get a transfusion of red blood cells. A blood transfusion is a safe, standard procedure in which blood is provided to you through an IV in one of your blood vessels.
A transfusion mandates meticulous matching of donated blood with the recipient’s blood. Getting a red blood cell transfusion will treat your anemia immediately. The red blood cells also give a rich source of iron that one’s body can reuse.
But, a blood transfusion is only a short-term remedy. Your doctor will need to find and treat the root cause of your anemia. Blood transfusions are generally reserved for those whose anemia places them at a higher risk for heart issues or other severe health problems.
