What Causes Low White Blood Cell Count?

A low white blood cell count, or leukopenia, can result from various factors. Bone marrow disorders, such as leukemia or aplastic anemia, impair white blood cell production. Infections like HIV or viral hepatitis can suppress counts. Autoimmune diseases, including lupus, attack white blood cells. Nutritional deficiencies, particularly vitamin B12 or folate, may contribute. Chemotherapy, radiation, or medications like ceftriaxone injection wholesale can reduce counts as a side effect. Other causes include severe infections, hypersplenism, or chronic diseases like liver failure. Diagnosis involves blood tests, and treatment depends on the underlying cause, potentially including medications or lifestyle changes.
