How long does it take to recover from blood loss anemia?
Sometimes it takes up to 6 months of treatment with iron supplements before iron levels return to normal. You may need to get iron through an IV if you have problems with the iron pills or if your body doesn’t absorb enough iron from food or iron pills.
When would you need a blood transfusion for anemia?
A: Anemia blood transfusions are necessary when the body cannot maintain enough oxygen-carrying red blood cells to survive without health problems. Excessive bleeding can cause anemia and blood transfusions replace lost red blood cells. Iron-deficiency anemia blood transfusions are only necessary in severe cases.
Will a blood transfusion help anemia?
A transfusion of red blood cells will treat your anemia right away. The red blood cells also give a source of iron that your body can reuse. However, a blood transfusion is only a short-term treatment. Your doctor will need to find and treat the cause of your anemia.

How quickly can you bleed to death?
