Excessive earwax build-up can occur when the natural production of earwax, which serves to keep the ears clean and free of germs, becomes too much and causes a blockage. While earwax usually exits the ears without causing any issues, in some cases, it can accumulate and obstruct the ear canal. Excessive earwax build-up can have various causes. Some individuals are more prone to blocked ears due to their natural tendency to produce a higher amount of earwax. Additionally, factors such as naturally hard or dry earwax, narrow or hairy ear canals, and aging can contribute to an increased risk of accumulating too much earwax. As people grow older, earwax tends to become drier, which can lead to blockages. Furthermore, the presence of bony growths in the outer part of the ear canal can obstruct the flow of earwax. It is worth noting that inserting objects into the ear canal can also cause earwax blockage. Practices like frequently using cotton buds, wearing ear plugs, or using hearing aids can disrupt the natural process of earwax removal and contribute to the build-up of earwax in the ear canal. It is advisable to avoid inserting such objects into the ears to prevent the risk of blockages and related complications.
