Bromhidrosis is a condition of abnormal grotesque body odor. Humans have 2 primary secretory glands: apocrine and eccrine. Eccrine glands are all over the entire skin surface and their most important role is thermoregulation through sweat. Ussually eccrine secretion is odorless, but can emanate an stale smell due if bacteria on the skin get a chance to break down. Apocrine glands are limited in the axilla, genital skin, and breasts. Apocrine glands are in charge of the pheromonic odor (personal scent). Apocrine sweat is also odorless, but within an hour of being on the skin the that bacteria live on the skin break down the sweat to produce an disagreeable body odor.
Hyperhidrosis. The body requires perspiration to regulate the body temperature. Sweat glands are are highly concentrated in the hands, feet, armpits and the genital regions. In this medical condition a person produces unpredictably excessive amounts of sweating even when the person is at rest or in a cool environment. Although perspiration is practically odorless, it can emanate an unpleasant smell when it comes into contact with bacteria on the skin.
c. Athlete's Foot
Athlete's foot is a skin infection caused by a fungus, usually between the toes, but it can spread to your toenails and the soles and sides of the feet. The fungus likes to attack the feet because shoes create a dark, warm, and damp environment which encourages fungus growth. Under cool, dry skin conditions, fungi remain inactive. But the more moisture there is, the more bacteria proliferate, and the greater the odor.
Scleroderma it is defined as excessive deposits of collagen in the skin, joints or other organs. When it hits the esophagus, it leads to difficulty swallowing, chronic heartburn and constant halitosis for 2 reasons: a. The scar tissue in the esophagus makes food from the stomach to go back up the esophagus, leaving a bitter, acidic taste in the mouth all the time.
e. Pitted Keratolysis
Pitted keratolysis is a skin disorder that affects the sole of the feet and, occasionally the palms of the hand. The feet become white with clusters of punched-out pits. It affects those who perspirate profusely especially if they wear shoes or boots for long periods. It is due to corynebacteria, and/or possibly the bacteria Dermatophilus congolensis. The infection of the soles causes very smelly feet.
