Understanding Low White Blood Cell Count (Leukopenia): Causes & Symptoms

A low white blood cell count, or leukopenia,is a condition in which an abnormally low amount of white blood cells are circulating in a person̵7;s blood. White blood cells fight diseases and infections in the body.

Viral Infections

• According to the Mayo Clinic, viral infections may reduce the ability of the bone marrow to produce white blood cells and cause low levels of white blood cells.

Cancer

• Leukemia or cancer of the bone marrow can cause the body to create fewer white blood cells.

Autoimmune Disorders

• Autoimmune disorders such as AIDS can cause the body to fight against its own white blood cells, reducing their number.

Other Medical Conditions

• Leukopenia can develop from allergies, hyperthyroidism or vitamin deficiencies. Patients with aplastic anemia may also experience low levels of white blood cells.

Drug Causes

• The use of drugs such as diuretics, antibiotics and prednisone may contribute to a reduced white blood cell count.
