Oily ears do not necessarily mean fox odor. Oily ears are often found in people who produce more oil and more fat in their bodies. Fox odor is related to the development of sweat glands in the armpits. People with fox odor generally have oilier ears and their skin produces more oil. Oily ears are not a specific symptom of fox odor, and the presence of oily ears alone does not diagnose fox odor. Oily ears are caused by excessive secretion of sweat glands in the external ear canal, which makes the ear wax appear as a soft, thin, yellow or sticky oily substance, which is more common in people with fox odor. Some people may have an endocrine disorder and a strong metabolism, resulting in excess oil in the body, which in turn produces oily ears, but no fox odor. If you have oily ears, try not to use cotton swabs to remove the earwax, as it is easy to push the earwax deeper into the ear canal and cause earwax embolism. If you want to clean your ears, you can go to the hospital and seek help from your doctor.
