Subtitle: Overview of Hearing Loss
Hearing loss is a natural part of the aging process for many people. Most age-related hearing loss, also known as presbycusis, occurs gradually over time. It is commonly linked to noise exposure, genetic conditions, and medical conditions like diabetes. It is estimated that one in three people between the ages of 65 and 74 has some degree of hearing loss. After age 75, nearly half of all people have hearing loss.
Noise-Induced Hearing Loss
Noise-induced hearing loss (NIHL) is caused by exposure to loud noises. It can occur at any age, but it is most common in people who work in noisy environments or who are frequently around loud sounds such as music or machinery. NIHL is permanent and can worsen over time. The most common symptom is a ringing in the ears, known as tinnitus.
Genetic Hearing Loss
Genetic hearing loss is caused by a gene mutation or a combination of gene mutations. It can be inherited from either a person’s parents or can be acquired during one’s lifetime. It is estimated that about half of all cases of hearing loss are due to genetic factors.
Medical Conditions
Some medical conditions, such as diabetes, can cause hearing loss. Diabetes can damage the tiny blood vessels in the inner ear, resulting in hearing loss. Other medical conditions that can cause hearing loss include high blood pressure, ear infections, allergies, Meniere’s disease, and auto-immune disorders.
Conclusion
Hearing loss is a normal part of aging for many people. It can also be caused by noise exposure, genetic factors, and certain medical conditions. People should be aware of the signs of hearing loss and should seek medical advice if they experience any symptoms.
