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 available 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.
P.S. Considered a medical emergency, “sudden sensorineural hearing loss” (SSHL), also known as “sudden deafness,” usually occurs in one ear, either immediately or over several days.
Hearing loss has many causes such as disease or infection, ototoxic drugs, exposure to noise, tumors, trauma, and the aging process. This loss may or may not be accompanied by tinnitus, ringing in the ears. While most causes of hearing loss are well-understood, researchers are still studying all the possible causes, methods for prevention and treatment options.
