Anemia is a common side effect of many chemotherapy treatments and affects seven out of ten people during their treatment. Anemia is a condition in which the body does not make enough healthy red blood cells. Red blood cells are produced in the bone marrow and carry oxygen throughout the body. When your red blood cells are very low, your organs and body tissues don't get enough oxygen and can't function properly. This is what causes the symptoms of anemia, such as weakness and fatigue. Your doctor will monitor your blood counts with regular blood tests, and prescribe transfusions and medications to increase your red blood cell count if needed. If the anemia is caused by a lack of nutrients, the doctor may prescribe vitamin B12, iron, or folic acid supplements.
Fatigue is a feeling of extreme tiredness or lack of energy, and is a common side effect of chemotherapy. Chemotherapy drugs can deplete your red blood cells and lead to a condition known as anemia. Red blood cells contain hemoglobin, which carries oxygen from your lungs to all parts of your body. Symptoms of anemia, such as fatigue, happen because your organs aren't receiving enough oxygen. Your doctor will perform regular blood tests to check for anemia, and can prescribe medications or transfusions to increase your red blood cell count if needed.
