If you’ve experienced multiple ear infections in a short period, you may wonder why they keep returning. Chronic ear infections occur when fluid gets trapped in the ear, causing an infection, and does not fully heal.
The following could be reasons for chronic ear infections:
Eustachian Tube Dysfunction
The Eustachian tubes are small passageways that connect the middle ear to the back of the throat. They help equalize pressure in the ear and drain fluid that may accumulate in the middle ear. However, if the eustachian tubes are not functioning properly, fluid can become trapped, creating an environment where bacteria and viruses can thrive, leading to infections.
Eustachian tube dysfunction can occur for several reasons. In children, the tubes are smaller, making it easier for fluid to become trapped. Allergies, colds or sinus infections can also cause inflammation and block the Eustachian tubes, increasing the risk of chronic ear infections. In some cases, structural abnormalities or enlarged adenoids can also interfere with proper eustachian tube function.
Treatment for Eustachian tube dysfunction may include the placement of tubes in the ears to drain the fluid.
Recurrent Respiratory Infections
Another common cause of chronic ear infections is recurrent respiratory infections. When you have a cold, flu or sinus infection, fluid can build up, leading to an ear infection.
Children are particularly susceptible to recurrent respiratory infections because their immune systems are still developing, and they are often in close contact with other children in settings like schools and daycare centers. Adults with weakened immune systems or underlying health conditions may also be more prone to these infections, which can contribute to chronic ear infections.
Persistent Allergies
Allergies can be another culprit behind chronic ear infections. Allergic reactions cause inflammation in the nasal passages and throat, which can lead to Eustachian tube dysfunction. Additionally, allergic reactions often produce excess mucus, which can accumulate in the middle ear and create a breeding ground for bacteria and viruses.
Common allergens like pollen, dust mites, pet dander and mold can trigger these reactions. If you suffer from seasonal allergies or have a known sensitivity to certain allergens, managing your allergy symptoms may help reduce the frequency of ear infections. In some cases, identifying and avoiding specific allergens can make a significant difference.
If you get recurrent ear infections, contact your doctor. Additionally, contact your doctor if your ear infection is accompanied by persistent fever or doesn’t resolve after treatment.
