Odd sweat is a condition in which the sweat secreted has a special odor or the sweat is decomposed to produce an odor. It is most often seen in areas where sweating, sweat does not evaporate easily and large sweat glands are located, such as the armpits, groin, feet, perianal area, vulva, umbilicus and under the female breast, with foot and axillary hyperhidrosis being the most common. Small sweat glands often accompany hyperhidrosis and are commonly found in the plantar and interdigital areas of the feet, where the odor is produced by bacterial decomposition of sweat. The sweat glands are influenced by endocrine secretion, and only in adolescence begins to secrete actively, so the sweat glands caused by oedema more in adolescence, to old age can be reduced or disappear. As bacteria interact with the secretions of the sweat glands to produce unsaturated fatty acids, the formation of a specific odor is caused. The majority of patients have a family history of oedema caused by sweat glands. The most common sites of oedema are the armpits, groin, feet, perianal area, vulva, umbilicus, and underneath the female breast, with foot and axillary oedema being the most common. Foot hyperhidrosis is often associated with sweaty feet, with a pungent odor, which is obvious in summer. Axillary hyperhidrosis, commonly known as fox, is a specific pungent odor, more pronounced in the summer. Patients are often accompanied by colored sweat, with a predominance of yellow. It is usually easy to diagnose based on the specific odor and its distribution. Patients are usually under great psychological pressure, which seriously affects school work and life, and surgical treatment is feasible for patients who have reached the age of 18 and are mature enough to relieve their worries. Traditional treatments include drug application (applied almost daily, poor results, treating the symptoms but not the root cause, troublesome), local skin excision (large scar range, painful upper arm activities, even limited), laser treatment (inaccurate results, prone to recurrence). Through minimally invasive surgery to remove large sweat glands, surgery pain is small, the postoperative effect is good, female patients after surgery to reduce axillary hair, there is a certain cosmetic effect, caused a good social effect, welcome the majority of patients consulting for help, surgery should be free of bleeding, infectious diseases and long-term oral aspirin and other drugs that cause bleeding (stop 1 week), women avoid menstruation, men avoid smoking and alcohol, wear cardigans loose clothing, postoperative shoulder joint Brake and rest for 10 days as prescribed by the doctor.
