Does oily earwax necessarily mean body odor?

Oil-like earwax generally refers to wet cerumen, while body odor usually refers to axillary bromhidrosis. Under normal circumstances, having oily earwax does not necessarily mean a person will have body odor; there is no direct causal relationship between the two. If discomfort occurs, it is recommended to seek timely medical evaluation and treatment at a reputable hospital. The details are as follows:

Wet cerumen is a type of earwax that is characteristically moist and sticky. The formation of oily earwax is primarily related to genetic factors—some individuals naturally produce ear canal secretions with higher lipid content. Axillary bromhidrosis (armpit odor), on the other hand, results from specific bacteria in areas such as the armpits breaking down sweat and producing an unpleasant smell. The development of body odor is closely linked to the types and activity levels of bacteria in certain body regions, as well as personal hygiene habits. Although both oily earwax and axillary bromhidrosis are associated with active apocrine (large) sweat glands, there is no direct cause-and-effect relationship between them. Having oily earwax does not necessarily indicate the presence of body odor, nor do all individuals with body odor have wet cerumen.

In daily life, it is recommended to maintain good personal hygiene and pay attention to one's health. If the above symptoms occur, medical consultation at a hospital is advised to prevent interference with everyday activities.
