Eosinophils: Role in Allergy and Parasite Defense

*Eosinophils are a type of white blood cell involved in combating parasitic infections, allergic reactions, and regulating immune responses. Changes in eosinophil levels help assess allergic conditions, parasitic infections, or certain blood disorders.

*Normal Range
Relative Percentage: <6%

*Elevated Eosinophils (Eosinophilia)
Causes:
-Allergic Diseases:
Conditions such as asthma, allergic rhinitis, or eczema.
-Parasitic Infections:
Hookworms, roundworms, or schistosomiasis.
-Drug Reactions:
Drug allergies or rashes caused by medications.
-Blood Disorders:
Hodgkin’s lymphoma or chronic eosinophilic leukemia.
-Other Conditions:
Autoimmune diseases like lupus.

*Effects:
Can lead to tissue damage, particularly in the airways or skin.

*Reduced Eosinophils (Eosinopenia)
Causes:
-Acute Infections:
Bacterial infections or sepsis.
-Stress Response:
Trauma, burns, or post-surgery stress.
-Steroid Therapy:
Long-term use of corticosteroids suppresses eosinophil production.

*Effects:
Often associated with stress or suppressed immune function.

*How to Maintain Healthy Eosinophil Levels?
-Prevent Allergies:
Avoid allergens like dust mites and pollen to reduce allergic reactions.
-Treat Parasitic Infections:
Maintain personal hygiene and ensure clean water and food intake.
-Avoid Medication Misuse:
Use antibiotics and steroids only under medical supervision.
-Regular Checkups:
Individuals prone to allergies or at high risk for parasitic infections should monitor eosinophil levels periodically.

*Conclusion
Eosinophils play a vital role in allergic reactions and parasite defense. Abnormal levels may indicate immune system issues or underlying diseases. Adopting healthy habits, practicing hygiene, and undergoing regular checkups can help maintain normal eosinophil levels. If abnormalities occur, seek medical evaluation for proper diagnosis and treatment.
