Earwax is a substance produced inside your ears. Its function is to keep the ears clean and free from germs.

Earwax usually passes out of the ears naturally, but sometimes too much can accumulate, blocking the ears. This build- up of earwax is a common problem that in most cases can be easily treated using drops bought from a pharmacy.

Some people are more prone to excess earwax than others. This is due to their body naturally producing too much earwax. Other factors that contribute to an earwax build-up include:

• Having narrow ear canals (the tube that connects the opening of the ear with the ear drum).
• Having excessively hairy ears.
• Naturally producing hard or dry earwax.
• Being elderly – as we age, our earwax can become harder and drier.
• Having bony growths in the outer regions of the ear canal.
• Using cotton buds or ear plugs – frequently inserting objects into the ear can cause a build- up.

Having an excess earwax build-up in your ear can cause the following symptoms:

• Loss of hearing
• Tinnitus (ringing in the ears)
• Earache
• An itchiness in or around the ear(s)
• Vertigo (a dizzy, spinning sensation)
• Ear infections

These symptoms will usually improve after the excess earwax has been removed.

It is recommended to contact your GP should any of the associated symptoms prove particularly troublesome. Also, see your doctor if over-the-counter remedies haven’t been effective after three to five days of use.

Your doctor or practice nurse will usually look inside the ear(s) to check whether they are blocked. They may also perform some simple hearing tests to ascertain the extent of the blockage. Depending on the result, they may suggest perseverance with ear drops, or alternatively, they may perform a minor procedure known as ear irrigation, which uses water to flush out the ear canal.

If these treatments prove unsuccessful, your doctor or practice nurse may refer you to the ENT (Ear, Nose & Throat) department of your nearest hospital. Here they can offer more specialised treatments, such as an aural toilet or microsuction.

It isn’t clear whether there is anything that can be done to prevent a build-up of earwax, although some doctors may recommend using ear drops regularly, which will keep the earwax soft, allowing it to pass from the ear more freely.

It is important not to attempt and scrape out the earwax using a finger or cotton bud. This may only serve to compact the wax, pushing it further into the ear canal. This will likely make the problem worse.
