Zhang is a white-collar worker, young and capable, she always gives people the impression of being confident, sunny and cheerful. However, every summer, an embarrassing problem always bothered her, and even caused a heavy psychological burden. Summer clothing is thin, with the increase in sweat secretion, Zhang’s armpits will give off a burst of unpleasant odor, which makes her afraid to get close to her colleagues and friends, seriously affecting her work and interpersonal communication. What is armpit odor? Zhang’s disease is called axillary odor, also known as fox odor, refers to the distribution of the body surface skin such as the axilla, perineum, back parts of the sweat glands (parietal sweat glands) secretions in the production of a special unpleasant odor. The sweating glands of the human body are divided into two types: small sweat glands and large sweat glands. The sweat from small sweat glands consists mostly of water, with only a few salts and metabolic products, and is nearly transparent and odorless in color. The secretion of the sweat glands has a kind of unsaturated fatty acids, and after the acidic decomposition of the fat in the sweat by the bacteria on the surface of the skin, unsaturated fatty acids and other substances will be produced, and these substances will give off a special smell, so that people avoid it and are afraid of it. Axillary odor is a hereditary disease, and most people with fox odor have a family history of inheritance. As the sweat glands in the adolescent secretion, so the disease is mostly seen in young adults, to the older age of the time can be reduced or disappear. Especially in the summer, armpit odor situation is more. This causes a heavy psychological burden to patients with axillary odor, resulting in a sense of inferiority, and then affect learning, work and interpersonal communication. If adolescents suffer from armpit odor, it can easily affect their mental health and even produce autism and depression, so armpit odor should not be ignored. What are the usual precautions? Director Zhao Jingjun of the Dermatology Department of Tongji Hospital suggests that such patients should pay more attention to personal hygiene, bathe regularly, change underwear regularly, keep the armpits dry and clean, do less excessive exercise, eat less stimulating food, maintain a regular life and emotional stability. What are the treatment methods? Topical medication External medication for armpit odor, most of them are to cover the odor with fragrance, which can only relieve or cover up the odor, not to treat the root of armpit odor, but only to relieve the symptoms of some patients and even no effect. Injections therapy external medication is not effective, you can choose local injection of botulinum toxin treatment. Botulinum toxin can paralyze the sympathetic nerves that innervate the sweat glands, blocking the sympathetic innervation of the sweat glands to achieve the effect of controlling sweat secretion. This is one of the newest treatments for the disease in recent years. It is the easiest local injection to achieve maximum benefit with few side effects, and is usually treated once a year in the summer. Botulinum toxin can be injected into the body by a health care professional in a precise location and in a quantitative manner, achieving the most satisfactory results immediately with the smallest dose. This method is convenient and safe, with no significant recovery period and no need for vacation, and is suitable for prepubescent patients and patients with very mild degrees. Surgical treatment Depending on the cause of axillary odor, destruction of the sweat glands is considered the key to its eradication. The parietal sweat glands usually develop rapidly during puberty and secretion gradually reaches its peak, so the best time for patients to receive surgical treatment is after puberty, otherwise they are prone to recurrence. The dermatology department of Tongji Hospital uses minimally invasive sweat gland removal to treat axillary odor, which can achieve more satisfactory results. The method is to open a 3-4 cm size incision in the armpit after local anesthesia and use surgical scissors or special scrapers to completely destroy and remove the sweat glands from the body under direct vision so that they no longer secrete sweat and the armpit odor is fundamentally cured and the problem of armpit odor is solved. The wound is sutured at the wrinkles of the armpit, and gauze and elastic bandage are taken to put pressure on the wound, and the wound is basically less obvious after one month. Within ten days after the operation, the arms should not be completely drooping, at least to maintain an angle of 45 degrees, and the upper arms should be unfolded at night when sleeping as they were during the operation, so that the wound is flatter and better in appearance after healing. It should be emphasized that there is no treatment that can guarantee that a treatment will never recur or be completely clean and odorless. Minimally invasive removal of sweat glands can achieve a clinical cure rate of more than 90% in one treatment, and the vast majority of patients can be satisfied in one treatment.
