One of the first questions you may have is: What caused my baby’s hearing loss? This is a normal reaction. Parents have a need to know a reason for the hearing loss. Sometimes the cause of hearing loss can be determined and sometimes it can not. Your doctor will guide you through the process to determine the cause of your baby’s hearing loss.The first step in the process is a review of your family history, your baby’s birth history, and an examination. The second step includes medical and laboratory tests.The test results will help the doctor determine the cause of your baby’s hearing loss.

Causes

Genetic factors and many diseases can cause hearing loss. Treatment for serious illnesses can also cause hearing loss. Environmental factors including head trauma can cause hearing loss. Sometimes the hearing loss is caused by a combination of factors.

About 50% of infant hearing loss is due to genetic factors. A genetic factor can be inherited or non-inherited and refers to the “code” that determines the unique characteristics of your baby. Twenty-five percent of infant hearing losses are non-genetic.

The remaining 25% are due to unknown causes. Learning about possible causes of hearing loss can help you provide specific information to professionals. The more information professionals have, the more likely they can help you find answers to your questions.
