Why does your hearing aid cause nasal congestion whenever you wear them?

Hearing aids can cause nasal congestion due to several factors, including the airflow obstruction they create in the ear canal, which may lead to a pressure imbalance that affects the Eustachian tubes. Additionally, the materials used in hearing aids can sometimes trigger allergic reactions or irritation in sensitive individuals. If the fit is too tight or if there’s inadequate ventilation, it could also contribute to discomfort and congestion. If this issue persists, it’s advisable to consult an audiologist or healthcare professional for further evaluation.
