What can I do for iron deficiency anemia if I can't absorb iron from my intestine?

Iron can be given by injection; this type of injection is usually given by a Hematologist (blood disease specialist). Intravenous iron delivers much more iron at one time to the bone marrow than oral iron, and the time required to complete injectable iron treatment is shorter than the time needed to correct iron deficiency with oral iron. There are some risks of allergic reactions to the injectable iron, so the iron injections must be monitored and performed in the physician's office.
