Neutrophils: Key Defenders Against Infection
*Neutrophils are the most abundant type of white blood cells, comprising 50%-70% of the total white blood cell count. They play a critical role in combating bacterial infections and managing inflammatory responses. Changes in neutrophil levels are important indicators of infection, inflammation, or immune system abnormalities.
*Normal Range
Relative Percentage: 40%-75%
*Elevated Neutrophil Levels (Neutrophilia)
Causes:
-Infections:
Most commonly bacterial infections, such as pneumonia or abscesses.
-Inflammation or Trauma:
Post-surgery, burns, or acute inflammatory conditions.
-Stress Response:
Triggered by physical exertion, stress, or heart attack.
-Blood Disorders:
Bone marrow diseases, such as chronic myeloid leukemia.
*Effects:
Elevated neutrophil levels usually indicate the body is fighting an infection or managing inflammation.
*Decreased Neutrophil Levels (Neutropenia)
Causes:
-Viral Infections:
Conditions like influenza, dengue, or HIV.
-Drug Effects:
Chemotherapy, immunosuppressants, or antibiotics.
-Bone Marrow Suppression:
Caused by leukemia or aplastic anemia.
-Autoimmune Diseases:
Such as lupus.
*Effects:
Lower neutrophil levels increase susceptibility to infections, often presenting as fever, recurrent infections, or weakened immunity.
*How to Maintain Healthy Neutrophil Levels?
-Balanced Diet:
Ensure adequate intake of vitamins (e.g., B12, folic acid) and protein to boost immunity.
-Prevent Infections:
Practice good hygiene, wash hands regularly, and stay up-to-date with vaccinations, especially for immunocompromised individuals.
-Avoid Harmful Substances:
Limit exposure to toxic chemicals and avoid excessive medication use.
-Regular Checkups:
Those with a history of infections, immune disorders, or chemotherapy should monitor neutrophil levels periodically.
*Conclusion
Neutrophils are the body's first line of defense against infections. Abnormal neutrophil levels may indicate infections, inflammation, or immune system issues. Maintaining a healthy lifestyle and undergoing regular checkups can help ensure neutrophil levels remain within the normal range. If abnormalities occur, seek prompt medical evaluation to determine the underlying cause and appropriate treatment.
