There are many causes of hearing loss. Some people are born with it due to a genetic condition or malformation of the structures that make up the auditory system. Other people may develop a hearing loss later in life as part of a hereditary condition. Here in San Antonio, one of the most common populations to demonstrate hearing loss are members of the military. This demographic is exposed to noise from aircraft engines, generators, weapons firing, and explosions. We also see hearing loss due to noise exposures such as fireworks or a surprise gunshot. Experiencing any loud sound, such as musical instruments, for extended periods is also responsible for hearing loss. Other causes of hearing loss may be related to medical conditions such as diabetes, heart disease, or even COVID-19. The treatments for different medical conditions, including certain antibiotics or loop diuretics, may also lead to hearing loss. Still, other people experience a sudden hearing loss that may be related to a virus or an autoimmune disease.
