Hearing Loss: What Causes It and How Can You Address It?
Published: Aug 07, 2024
Hearing loss is a common issue that many people face as they age, but it can also occur for several other reasons. Understanding the different types of hearing loss and their causes can help in managing this condition effectively.
Understanding Hearing Loss
Hearing loss can be categorized into three types: sensorineural, conductive, and mixed. Sensorineural hearing loss involves the inner ear or auditory nerve and is often permanent. Conductive hearing loss is related to problems in the outer or middle ear that block sound waves. Mixed hearing loss is a combination of both types, affecting multiple parts of the ear.
Causes of Conductive Hearing Loss
Conductive hearing loss can be caused by issues in the outer ear, such as earwax buildup or infections, or in the middle ear, like otitis media or eustachian tube dysfunction. These conditions often block the passage of sound waves, resulting in reduced hearing ability.
Causes of Sensorineural Hearing Loss
Sensorineural hearing loss can result from age-related changes, known as presbycusis, or from exposure to loud noises, which damages the inner ear structures. It may also be caused by infections, genetic factors, or certain medications that are toxic to the ear.
