Are Frequent Ear Infections a Sign of Allergies?

Frequent ear infections are often a symptom of allergies, particularly in children, and may indicate reactions to food allergens such as dairy and wheat or environmental triggers including mold, pollen and dust mites.

  1. Significance

    • Exposure to allergens causes chemical histamine releases. Histamine leads to swelling, which results in mucus production, leading to congestion of the ears, eyes, nose and throat.

    Potential

    • Allergic reactions may include symptoms of allergic rhinitis---a condition resulting from excess fluids with symptoms of sneezing, runny nose, coughing, itchy, watery eyes and ear infections.

    Function

    • The Eustachian tubes typically function to drain the middle ear. Allergic rhinitis causes excess fluid to infiltrate the upper respiratory system connecting to the Eustachian tubes, hindering drainage.

    Effects

    • Allergies cause fluid blockage in the Eustachian tubes, preventing debris, wax and mucus from draining properly. Moisture in the ear promotes the growth of bacteria and viruses, causing ear infections.

    Prevention/Solution

    • Symptoms of ear infections include middle ear pressure, throbbing pain and decreased hearing. Ear infections are remedied with antibiotics and may be avoided by treating allergies with decongestants, antihistamines and corticosteroids.
