Leukopenia is a medical condition characterized by a lower-than-normal number of white blood cells in the body. White blood cells are crucial for the immune system, helping to fight off infections and diseases. A decrease in these cells can make individuals more susceptible to infections and can be caused by various factors, including certain medications, autoimmune disorders, or bone marrow problems. Diagnosis of leukopenia typically involves blood tests that measure the white blood cell count. Treatment depends on the underlying cause and may include medications, lifestyle changes, or addressing any related conditions, such as autoimmune disorders or bone marrow diseases. Regular monitoring is essential for managing this condition effectively.
