White blood cell (WBC) counts may not increase due to several factors, including nutritional deficiencies and infections.
Nutritional Deficiencies
A lack of essential vitamins and minerals can hinder WBC production. Specifically, deficiencies in vitamin B12, folate, B6, copper, and zinc are known to impact white blood cell counts. These nutrients play crucial roles in cell growth and division, processes vital for the creation of new WBCs. Ensuring adequate intake of these nutrients through diet or supplementation, under medical supervision, is essential for optimal WBC production.
Infections
Certain viral infections can suppress WBC production, leading to persistently low counts. Examples include tuberculosis (TB), HIV, hepatitis B, and hepatitis C. However, diagnosing these infections requires more than just a single WBC count test. Further investigations, such as specific blood tests and imaging, are needed to confirm these diagnoses. Treatment for the underlying infection is crucial for restoring normal WBC levels.
Other Potential Causes (Not mentioned in reference but relevant)
While the provided references focus on nutritional deficiencies and viral infections, it's important to note that other factors can contribute to low WBC counts. These include:
- Bone marrow disorders: Conditions affecting the bone marrow, where WBCs are produced, can significantly reduce their numbers.
- Autoimmune diseases: The body's immune system may attack and destroy WBCs.
- Certain medications: Some medications can have WBC suppression as a side effect.
- Severe infections: Overwhelming bacterial or fungal infections can initially cause a drop in WBC count before a later increase as the body fights the infection.
- Chemotherapy and radiation therapy: These cancer treatments can damage bone marrow and reduce WBC production.
It is crucial to consult a healthcare professional for proper diagnosis and management of low WBC counts. A thorough examination, including a complete blood count (CBC) and potentially further testing, is necessary to determine the underlying cause and recommend appropriate treatment.
