What are the causes of osmidrosis?

1, bromhidrosis is considered bromhidrosis. The apocrine glands distributed under the armpits of patients with osmidrosis secrete exuberant sweat, but the sweat secreted by apocrine glands is special, containing sugars, protein and unsaturated fatty acids. After these organic components are decomposed by bacteria under the armpit, they will produce short-chain fatty acids, ammonia and other substances, which will produce a special smell after mixing.

2. Etiology:

(1) Apocrine glands sweat.

Apocrine glands only exist in axilla, areola, umbilical fossa, anus, vulva and external auditory canal, and the function of other parts except axilla is extremely weak, resulting in little sweat. Sweat secreted by apocrine glands is sterile at first. Under the action of microorganisms, the organic matter in sweat decomposes to form short-chain fatty acids and ammonia with special odor, which leads to the occurrence of apocrine glands.

(2) sweating.

Often occurs in the palm and sole, rubbing area, and sweating is often colorless and tasteless. However, in the case of hyperhidrosis, sweat is interpreted by parasitic bacteria on the skin surface to release fatty acids and produce a special smell; Other substances such as garlic and arsenic can be excreted through exocrine glands, thus producing odor.

(3) when the mental or nervous system is damaged (such as paranoia and schizophrenia). ), it will also produce smelly sweat.

(4) The occurrence of bromhidrosis may be related to heredity.
