Because hearing loss is so prevalent among older individuals, researchers have sought to find factors that will help identify those at increased risk. This research has recently yielded the finding that “sudden sensorineural hearing loss” (SSHL), during which hearing is severely reduced over a three-day period, is linked with “iron deficiency anemia” (IDA). This common condition is caused by a lack of iron in the body, which leads to fewer red blood cells that carry oxygen around the body. As a result, IDA reduces the amount of oxygen to tissues. While the exact mechanism by which anemia leads to hearing loss is unknown, IDA is easy to treat. This correlation may prompt new ways to diagnose and treat SSHL. Sudden deafness usually occurs in one ear, and a medical evaluation along with a hearing evaluation by an Audiologist should happen within 24 hours for appropriate treatment.
If you or someone close to you is suffering from loss of hearing, you may want to know more about its causes, as well as what you can do to seek help. While seeing an Audiologist is the best course of action to take for hearing help, the supportive professionals from Cortland Hearing Aids in New York have provided a brief, but informative, overview to familiarize you with the different types of hearing loss below.
The three types of hearing loss are categorized according to the part of the auditory system that has been compromised and include:
- Sensorineural Hearing Loss: Called SNHL for short, sensorineural hearing loss is a result of inner ear damage. It can also occur when the nerve pathways traveling from the inner ear to the brain become damaged. It is the most common type of permanent hearing loss and can be caused by age, genetics, serious illnesses, certain drugs, head trauma, and exposure to loud noises.
- Conductive Hearing Loss: Unlike SNHL, conductive hearing loss happens when sounds aren’t carried properly through the outer ear, eardrum, and bones in the middle ear. This specific form of hearing loss can often be corrected and may be a result of infections, allergies, fluids, impacted earwax, or benign tumors.
- Mixed Hearing Loss: Just as its name suggests, mixed hearing loss takes place when a patient experiences both SNHL and conductive hearing loss. This means both the inner ear and the middle or outer ear are somehow damaged.
An evaluation can help determine which type of loss of hearing you’re experiencing. This will aid your audiologist in suggesting targeted solutions for your unique needs. To set up an evaluation at Cortland Hearing Aids, call (888) 614-8064, or visit their website.
