What Does Your Earwax Reveal About Your Health?

earwaxHealth

Ear wax is a completely natural wax-like substance, secreted by special glands in the skin on the outer part of the ear canal. Earwax assists in repelling water and trapping small dirt and dust particles from entering your inner ear canal.

When you think about it, it’s kind of weird how much the “gross stuff” our bodies produce can tell us about our health. A saliva sample can detect anemia; feces can pinpoint various types of cancer; urine can detect problems of the bladder, kidney and prostate…and so on. Turns out that our earwax can also tell us quite a bit.

First, we’ll talk a bit about the stuff and why it’s there. Then we’ll discuss what earwax tells us our health.

What is earwax?

As its name implies, earwax is a yellow waxy secretion of the ear. It is produced by the cerumen (suh-roo-mun) glands underneath the skin of the external ear canal (the part located between the fleshy and middle parts of the ear).

When most of us (including this writer) think of earwax, we just think of it as some nasty byproduct that needs a Q-tip once in a while. Actually, earwax is quite important. In fact, it serves these roles:

  • Moisturizes and protects the skin.
  • Prevents dry, itchy ears; especially within the ear canal.
  • Contains chemicals that ward off potential ear infections.
  • Helps prevent damage to the ear drum by suppressing outside noise.
  • Traps dirt, dust and other foreign agents that enter the ear canal.

What Does Your Earwax Reveal About Your Health?

The color and consistency of earwax (as with the other “gross stuff”) is important. As with pee, poop and spit, earwax should appear and feel a “certain” way. With that in mind, if your earwax looks like this…it may mean this…

1. It’s dry or sticky

This one is kind of cool, and it’s less about health than it is about genetics (though the two aren’t always mutually exclusive.) In an article published in the journal Nature Genetics, researchers discovered that the consistency of our earwax can clue us in on our ancestry. More specifically, the climate (thereby, location) in which our ancestors lived.

The authors explain: “Human earwax consists of wet and dry types. Dry earwax is frequent in East Asians, whereas wet earwax is common in other populations.” It all depends on the ABCC11 gene, which has a dry consistency. This gene increases according to geographic location, observed as a “north-south and east-west” downward trend.

2. It’s absent

If you notice an almost complete lack of earwax, which is usually noticeable when trying to clean your inner ear, there’s probably not much to worry about. However, it feelings of pain or stuffiness are present, it could indicate a rare condition known as “keratitis obturans.” This condition causes a hard buildup of wax deep within the ear canal.

As a precaution, it may be worth taking a trip to a family physician (FP) or an ear specialist – an otolaryngologist.

3. It’s leaking

When debris accumulates within the ear canal, it usually discharges through natural mechanisms or cleaning of the ear canal. When this debris noticeably leaks from the ear, it may indicate an abnormal skin growth called “cholesteatoma.”

Other symptoms of this condition include feelings of pain or pressure within the ear. These symptoms result from a “cyst-like” growth creating pressure within the canal.

It’s a good idea to see a specialist or FP in this case.

4. It’s scaling or flaky

This is no big deal, really. As with many other glands, the cerumen loses moisture as it ages. As a result, our earwax will also scale or flake.

Chalk it up to getting older.
