Some people are naturally prone to earwax building up in their ears and may need frequent treatment to remove it when it becomes a problem.
It's not clear if there's anything you can do tostop earwax blocking your ears, although some doctors recommend using eardrops regularly to keep your earwax soft.
Don't try to scrape out the earwax with your finger or an object inserted into your ear, as this this can make the problem worse.
Speak to your doctor for advice if earwax builds up in your ears regularly.
