What is the term for a disorder causing unpleasant odors from the armpits?

The term that refers to a disorder causing unpleasant odors from the armpits is bromhidrosis. This condition arises from the interaction of sweat with bacteria that naturally reside on the skin, leading to a breakdown of sweat components and the production of odor-causing substances.

Bromhidrosis specifically involves the apocrine glands, which are primarily located in the underarm area and become active during puberty. When these glands produce sweat, if it is not properly managed through hygiene practices, the resultant bacteria can multiply and lead to noticeable odors.

Hyperhidrosis, although related to excessive sweating, does not specifically imply a problem with odor and can occur without the presence of any foul smell. Dermatitis refers to inflammation of the skin and can manifest in various ways, often unrelated to sweat or odor. Acanthosis generally indicates a thickening of the skin and is often associated with different dermatological conditions but does not pertain to odor production. Understanding these distinctions is crucial for recognizing and addressing the specific condition.
