Smelly sweat

Introduction Bronchidrosis (bromhidrosis) refers to the odor of sweat, there are two types of generalized odor and local odor, the latter is common with odor and foot odor.

Cause

A large amount of odorous sweat on human skin is often caused by abnormal sweat secretion from the apocrine glands. Mainly distributed with ankles, areola and perineum, external auditory canal, often more women. The apocrine glands are affected by endocrine, which gradually increases in childhood and gradually decreases or disappears in old age. Some patients have a family history clinically and may be related to heredity. Foreigners with chronic sweating are more and more serious. Some substances such as curry, onion, wine, and arsenic can have a special odor.

The sweat secreted by the normal small sweat glands is often odorless, but in the case of excessive sweat, the sweat is decomposed by the surface epigenetic bacteria, releasing fatty acids and forming odor, which is the reason for the effective use of topical antibacterial drugs, and the rare form of blisters It can be produced when the mind or nervous system is damaged. Systemic dysentery is often a physiological change, usually related to nerves, only a few are pathological, patients with dysentery are often accompanied by sweating, and some people have statistics of 100 cases of dysthymia with 86 cases of hyperhidrosis .

Differential diagnosis

Differential diagnosis of dysentery:

1, apocrine sweat glandular odor sweat: apical sweat glands only exist in the armpits, areola, umbilical fossa, anus, vulva and external auditory canal, etc., except for the armpit, the gland is extremely weak in other parts, resulting in sweat less. The sweat secreted by the apocrine sweat glands is initially sterile. Under the action of microorganisms, the organic matter in the sweat is decomposed to form a short-chain fatty acid and ammonia with a special odor, which leads to the occurrence of apocrine sweaty gland sweat.

2, small sweat glandular odor sweat: often occurs in the palm sputum and rubbing area, small sweat is often colorless and odorless, but in the case of excessive sweat, sweat is decomposed by the surface of the skin parasitic bacteria to release fatty acids, etc., which produces a special odor Other substances such as garlic and arsenic can cause odor through excretion of small sweat glands.
