Loss of the Gag Reflex
The vagus nerve is the 10th cranial nerve that extends from the brainstem down to the chest. It is a mixed nerve consisting of both motor and sensory fibers. The vagus nerve plays an important role in many bodily functions, including controlling the gag reflex.
And when it comes to the gag reflex, damage to this nerve can result in a complete loss of the reflex or a partial loss. A complete loss of the gag reflex means that a person will not experience any sensation when something triggers their gag reflex, such as when food or vomit is touching their throat. A partial loss means a person may still have some sensation, but it will be significantly reduced.
For people experiencing symptoms associated with vagus nerve damage, it’s important to see a doctor so they can perform tests to rule out any other potential causes. Treatment for vagus nerve damage will depend on the underlying cause. In some cases, such as with certain infections, treatment may be able to reverse any damage that has been done. However, the damage may be permanent in other cases, such as with certain autoimmune diseases or cancer treatments.
