Causes Of Low Rbc

Certain medications can lead to low RBCs in the body.
 Anemia is caused by having a low red blood cell count. Red blood cells, or RBCs, contain a protein called hemoglobin, which carries oxygen to the different tissues of the body. The amount of oxygen that is supplied to the different tissues depends on the amount of RBCs present in the body. In anemia, the body does not have enough hemoglobin in the red blood cells, which leads to a lack of oxygen supply to the tissues. According to Medline Plus, there can be a number of causes of low RBC.

Most of the red blood cells are produced by the bone marrow, which is a soft tissue in the center of the bones. Certain conditions affecting the bone marrow can lead to a low RBC count. These conditions include leukemia, multiple myeloma, and lymphoma. The kidneys produce a hormone called erythropoietin which signals the bone marrow to produce more red blood cells. In individuals with kidney failure, the production of this hormone is affected. This can cause a low RBC in individuals.
