Eosinophils: A Key Biomarker for Allergies & Immunity

Eosinophils are a type of white blood cell that play a key role in the body's immune response, particularly in fighting parasitic infections and mediating allergic reactions.‍Eosinophils are part of the granulocyte family of cells, which are all characterised by the presence of granules that contain enzymes and other proteins used to combat pathogens.‍These eosinophils specifically target and destroy parasites, while also contributing to allergy-related inflammatory responses.‍Measuring eosinophil levels can provide valuable insights into the state of your immune system and your body's response to certain health conditions.

Eosinophil levels are closely related to your healthspan as they reflect the body's capacity to respond to infections and manage inflammation.‍Normal eosinophil counts indicate a well-functioning immune system.

If you have allergic conditions, avoid allergens such as pollen, pet dander, or mold.‍Regular use of antihistamines or steroid inhalers prescribed by a healthcare provider can help reduce allergic reactions and eosinophil levels.‍ If eosinophil elevation is due to a parasitic infection, antiparasitic medications prescribed by a healthcare provider can help lower eosinophil levels.‍ In cases where eosinophilia is linked to inflammatory conditions such as asthma, a diet rich in anti-inflammatory foods like omega-3 fatty acids, turmeric, and green leafy vegetables can help manage inflammation.

Elevated eosinophil counts often indicate allergic reactions, parasitic infections, or autoimmune conditions.‍Conditions like asthma, eczema, hay fever, allergic rhinitis, and eosinophilic esophagitis are commonly associated with increased eosinophil levels.‍Low eosinophil levels are typically not a cause for concern, as they are generally considered normal. However, low levels can sometimes occur in response to acute infections, stress, or steroid use, which suppresses the immune system.‍Eosinopenia is often a temporary condition and may not require specific treatment unless linked to an underlying health issue.
