It does actually serve a useful purpose. In fact, it serves a few useful purposes. For starters, it protects the skin of the ear canal, assisting in the cleaning and lubrication of the area. It also acts as protection against foreign objects like insects, fungi, bacteria, excess water and dust.
But it can also cause some problems for its hosts. When cleaning the ear, if it does incorrectly can actually cause temporary and permanent hearing problems.
A simple excess of earwax can cause hearing difficulties. But the problem can be exacerbated when cleaning the ear. If the wax is accidentally pushed deeper it can cause more hearing loss and the need for professional help to alleviate the condition.
Luckily, treatment for such a situation can be easily rectified by visiting a doctor or hearing specialist. The treatment is usually fairly quick and painless, and should result in hearing being restored to full capacity.
One of the most common causes for excess earwax is excessive use of earphones when listening to music or other audio. With our reliance on technology these days, this has become more of a prevalent reason for temporary hearing issues.
Excess buildup of earwax should generally come with a range of warning signs apart from the obvious difficulty with hearing. It can also lead to pain in the ear, fever, coughing, and dizziness. If any of these more severe factors are prevalent in your everyday life, then it is definitely time to seek medical help.
So, as you can see there can certainly be a connection between earwax and hearing loss, but thankfully it is usually not linked to anything permanent as long as the issue is dealt with promptly.
