When white blood cell levels are low, doctors often recommend healthy lifestyle habits such as eating a balanced diet, exercising regularly, and getting enough quality sleep. These steps can help support the immune system and improve overall health.
The most common causes of low white blood cells include:
-
Viral infections, such as mononucleosis or hepatitis
-
Nutrient deficiencies, especially vitamin B12 or folate
-
Side effects of medications, such as chemotherapy drugs
-
Autoimmune conditions, such as systemic lupus erythematosus or rheumatoid arthritis
-
Bone marrow problems, which affect the production of white blood cells
Whenever possible, treatment to increase white blood cells should focus on the underlying cause. Depending on the situation, it may include antibiotics, vitamin B12 supplementation, or corticosteroids, always under medical guidance.
