1. Ear Infections
- Otitis media – Infection of the middle ear, common in children. Can cause temporary hearing loss due to fluid buildup.
- Otitis externa ("swimmer’s ear") – Infection of the ear canal. Swelling can block sound from entering.
2. Age-related Hearing Loss
- Presbycusis – Gradual hearing loss as you age. It usually affects high-frequency sounds first.
3. Noise-Induced Hearing Loss
- Caused by loud sounds (concerts, headphones, machinery).
- Can be temporary or permanent depending on exposure.
4. Earwax Blockage
- A buildup of wax can prevent sound from reaching the eardrum.
5. Meniere’s Disease
- A disorder of the inner ear causing:
- hearing loss
- tinnitus (ringing)
- vertigo
- Episodes can come and go.
6. Otosclerosis
- Abnormal bone growth in the middle ear prevents proper sound conduction.
7. Acoustic Neuroma
- A benign tumor on the nerve that connects the ear to the brain.
- Causes gradual hearing loss, tinnitus, and balance issues.
8. Autoimmune Inner Ear Disease (AIED)
- When the immune system mistakenly attacks the inner ear.
9. Sudden Sensorineural Hearing Loss (SSHL)
- Rapid, unexplained loss of hearing (often in one ear).
- Needs urgent medical attention.
10. Ototoxic Medications
Some drugs can damage hearing, such as:
- certain antibiotics
- chemotherapy drugs
- high doses of aspirin or diuretics
11. Genetic Conditions
- Some people inherit conditions that cause hearing loss, such as:
- Usher syndrome
- Pendred syndrome
- Waardenburg syndrome
12. Viral & Bacterial Infections
These can damage the inner ear or auditory nerve:
- Measles
- Mumps
- Meningitis
- Syphilis
- HIV
- COVID-19 (in some cases)
13. Tympanic Membrane Perforation (Eardrum Perforation)
- A hole or tear in the eardrum caused by:
- infections
- trauma (e.g., cotton swabs, loud blasts)
- rapid pressure changes (barotrauma)
- Can cause:
- temporary hearing loss
- ear pain
- drainage
- increased infection risk
I will discuss each of the above Diseases & Conditions individually in future posts.
