1. There are two types of sweat glands in the human body: macrohidrosis and microhidrosis. The former is narrowly distributed, only in the armpit p external ear canal and vulva, the latter is distributed throughout the body; because of the large cell gap of the sweat glands, resulting in its secretions contain a large number of unsaturated fatty acids, by the decomposition of the bacteria present on the surface of the skin can produce small molecules of organic matter with odor, while the secretions of small sweat glands are mainly various types of salts and water. It can be seen that the smell of armpit odor requires two conditions: the body surface bacteria and sweat gland secretions, one without the other. Therefore, the smell of armpit odor is obvious in summer when sweating is more. 2, no matter what people, in the case of a lot of sweating, if not bathing or changing clothes, their armpits more or less smell, that is, usually normal people for various reasons may also suddenly have a bad smell. Some patients hope that they do not smell after treatment is not realistic, because everyone will have body odor, even if there is no armpit odor people sweat more or do not bathe for a long time will have odor. 3, there is no treatment to ensure that a treatment to never recur or completely clean and odorless degree. In terms of minimally invasive surgery in our department, the clinical cure rate can reach more than 90-95% with one treatment, and most patients can be satisfied with one treatment through surgery, individual serious relapse but will be less than before, minor patients are generally not advocated for surgery, to be considered after the development of maturity, individual serious fox odor insist on surgery may need to do a second time with the development of the body. 4, the surgical incision is about 1 cm more, two stitches, stitches in the armpit wrinkles, a month after the basic is not too obvious. You can take a shower on the tenth day after surgery. Female patients should not operate during menstruation to avoid easy formation of post-operative hematoma. Surgical treatment is not recommended for those who have scars. 5.Some patients are worried that they will be heavier than before or metastasis will occur after surgery before they are done, which is unnecessary and does not make sense from the medical point of view. 6.Those who are demanding for the post-operative efficacy or those who are overburdened with psychological burden or those who are too skeptical are not suitable for the treatment. 7, some cleanliness seekers should not confuse the normal body odor with the smell of fox and ask for surgery, just pay attention to cleanliness and hygiene. Those who do not have fox odor but have hyperhidrosis, local injection of BOTOX is recommended.
