If you are feeling fatigued, it is important to talk to your doctor right away because fatigue is treatable and controllable. In addition, a condition called anemia has been linked to feelings of fatigue in cancer patients. Red blood cells carry oxygen from the lungs throughout your body, a process that is crucial to maintaining a normal energy level. Due to the disease or treatment for the disease, your RBC level may decrease and your body tissues may not be getting enough oxygen, which leads to feeling fatigued. Mild anemia, resulting from a lack of iron in the diet, can be improved by adding supplemental iron to the diet.
Severe anemia is treatable through methods such as blood transfusions.
However, this method has risks such as allergic reactions, fevers, chills, and headaches. It may also be inconvenient and time-consuming. Another way to treat anemia is with Epoetin alfa, a synthetic version of the human hormone erythropoietin, which stimulates your bone marrow to produce red blood cells. This therapy may or may not be combined with oral or intravenous iron as a dietary supplement. Epoetin alfa is given by injection and does carry the risk of side effects.
