Armpit odor (commonly known as fox) has always been a sensitive problem for many young people, especially young women, suffering from armpit odor, often distressed; especially in the summer, the armpits emit a strong special odor, seriously affecting their daily lives such as dating, marriage and job hunting. Consultation on the treatment of armpit odor has been a hot topic. Question 1: How is armpit odor produced? Doctor: There are two types of sweat glands in the human body: the sweat glands and the small sweat glands. The former is relatively limited in distribution, only in the armpit p external ear canal and vulva, the latter is distributed almost everywhere in the body; sweat secreted by the sweat glands, containing a large number of unsaturated fatty acids, fatty acids are decomposed by bacteria on the surface of the skin, you can produce a strong odor of small molecules of organic matter, is the main source of armpit odor; and the secretions of small sweat glands are mainly various types of salt and water. It can be seen that the production of axillary odor requires two conditions: bacteria on the body surface and secretions from the sweat glands. By adolescence, the secretion of the sweat glands is more, the skin of the armpit is warm and moist, poorly ventilated, often with a large number of bacteria, so the smell of armpit odor is obvious in summer when sweating is more, and poor hygiene habits of people with armpit odor will be very obvious. Question 2: What are the symptoms of armpit odor? Is it harmful to the human body? Doctor: People with axillary odor generally show: wet or sticky ear canal; sticky underarm sweat, yellow underwear odor; white crystals in the armpit hair, unpleasant odor after touching the armpit; 2-3 meters away, others can smell the pungent odor; body odor is obviously different from normal people, the smell of sweat in the normal state is heavy. Axillary odor is not harmful to the human body, so it can not be said that it is a disease, but axillary odor can seriously affect normal life and social life, so it can also be said that axillary odor is not good for health. Question 3: What are the treatment methods for armpit odor? Doctor: There are mainly surgical treatments and non-surgical treatments. The production of armpit odor is related to the above two factors, so methods that can reduce the secretion of sweat glands and reduce the number of bacteria on the surface of the armpit skin can be effective. People with armpit odor should bathe regularly, change clothes regularly, use neutral soap such as comfortable good to clean the sweat glands more concentrated places, and develop the habit of bathing in the morning and evening. Topical application of ice chips, talcum powder, cecropia, to reduce sweat secretion. Topical application of 75% alcohol or 0.5% androlatum (PVP-I disinfectant) can be used to kill local bacteria. If the odor is more pronounced and topical medications are not effective, then surgical treatment is required. Question 4: I have seen a lot of advertisements on the internet selling topical medication for armpit odor, saying that rubbing it for a month will completely eliminate the odor and it will never come back. I wonder if it is credible? Doctor: Topical medication is the application of a variety of antibacterial, astringent, antiperspirant, antiseptic, anti-odor and other effects of drugs applied to the armpit, so as to achieve the elimination of armpit odor treatment method. The advantages are simple and easy, non-invasive and painless, but only effective for those with mild symptoms, because the sweat glands are not destroyed, so it is easy to relapse and requires repeated medication, and some patients may have local allergic reactions. Therefore, if the topical medication is produced by regular manufacturers and approved by the state, those with mild symptoms can give it a try, but the claim of no more relapses is not credible. Question 5: Recently, I saw a piece of information that you can use local injections to treat good armpit odor, I wonder if it is effective? Doctor: Local injection is to inject alum liquid, anhydrous alcohol, elimination of hemorrhoid liquid, etc. into the bilateral axilla subcutaneously, so that the surrounding tissue produces sterile inflammation, and then adhesions occur, thus achieving the purpose of destroying the gland or blocking its elimination pathway. However, this method is generally suitable for patients with mild symptoms and fear of surgery. The advantages are simple operation, little pain, and short treatment time. The disadvantage is that the amount of drug injection is not easy to control: if too much drug is injected, it can lead to vascular embolism and cause subcutaneous necrosis; too little injection cannot achieve the purpose of treatment, and there may be subcutaneous sclerotic nodules appear after the injury heals. Question 6: I suffer from armpit odor, and the nature of my work is to deal with people frequently, so armpit odor makes me feel very distressed and affects my work life very much. I learned that many institutions are now treating armpit odor by laser, and they say the results are very good. However, I read some information on the Internet and it said that there is still a possibility of recurrence after laser treatment. Will it come back or not? Doctor: Freezing, laser, electrocoagulation and other methods are used to destroy the sweat glands by producing a thermal or cold effect in the axillary hair area, so that the skin forms scar tissue and blocks the discharge of glandular secretions, thus achieving the purpose of treatment. The advantage of this method is that it is easy to operate and the damage is small, but the disadvantage is that the requirements for operation are relatively high, and some patients may be left with cauterization scars in the axilla, and serious scar hyperplasia may occur, even causing bilateral upper limb activity restrictions; laser therapy can destroy or damage the sweat glands in the axillary area, but the distribution of sweat glands is very complex, and it is difficult to ensure the destruction of all sweat glands in practice, so a high recurrence rate can occur after three months The relapse rate is higher after three months; cryotherapy can damage the sweat glands and hair follicles to a certain extent, but due to the varying degrees of damage, relapse is more common in about three months. Question 7: I heard that armpit odor can only be completely treated by surgery, is it really so? Doctor: From the physiological anatomy, sweat glands are located in the deep skin and fat layer, sweat ducts open in the upper third of the hair follicles, a few directly on the surface of the skin, axillary odor surgical treatment is through surgery to destroy the human sweat glands or cut off the sweat ducts, to prevent the discharge of sweat, so that the root of the purpose of getting rid of sweat odor. Therefore, the current method of complete treatment of armpit odor or surgical methods. Commonly used surgical methods are axillary skin excision and minimally invasive axillary odor stripping, the latter more commonly used. Axillary skin excision: the purpose of this method is to remove the sweat glands, surgery along the axillary hair growth area to make a shuttle-shaped incision, using a knife to separate the skin to reach the edge of the axillary hair, all the skin with axillary hair will be removed, and finally suture the incision. The advantage is that the treatment is clean, thorough and not easy to recur. However, the disadvantages are very obvious: the incision is large, and often because too much skin is removed, the tension at the incision is too great, which affects healing, or scar contracture is formed after healing, and in serious cases, the upper arm is lifted up to produce a pulling sensation, which affects the movement of the upper limbs. When wearing swimsuits or lifting the arm in summer, the scar is often visible and affects the aesthetics, which makes it unacceptable to many patients. Therefore, this procedure is only suitable for patients with severe armpit odor. Axillary odor stripping: The principle of this method is to destroy the sweat ducts and make them break, thus preventing the secretion of sweat.
