Armpit odor (commonly known as fox) has been a sensitive problem plaguing many young people, especially young women, suffering from armpit odor, often distressed by this; especially in the summer, the armpits emit a strong special odor, seriously affecting their daily lives such as dating, marriage and job hunting. Question 1: How does armpit odor arise? There are two kinds of sweat glands in the human body: the sweat glands and small sweat glands. The former is relatively limited in distribution, only in the armpit p external ear canal and vulva and other parts of the body, the latter is distributed almost everywhere; 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 two conditions are needed for the production of axillary odor: bacteria on the body surface and secretions from the sweat glands. By adolescence, more secretion of the sweat glands, warm and moist skin in the armpits, poor ventilation, often a large number of bacteria breeding, so the smell of armpit odor is obvious in summer when sweating more, poor hygiene habits of people with armpit odor will be very obvious. Question 2: What are the symptoms of armpit odor it is harmful to the human body People with armpit odor generally show: damp or sticky at the ear canal; sticky underarm sweat, underwear with odor yellow; armpit hair with white crystals, hand touching the armpit after an unpleasant smell; distance 2-3 meters, others that can smell the pungent odor; body odor is obviously different from the norm, the smell of sweat in the normal state is heavy. Armpit odor is not harmful to the human body, so it can not be said that it is a disease, but armpit odor can seriously affect normal life and social life, so it can also be said that armpit odor is not good for health. Question 3: What are the treatments for armpit odor? The main points are surgical 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 gland secretion. Local use of 75% alcohol or 0.5% androlatum (PVP-I disinfectant) to kill local bacteria. If the odor is more pronounced and topical medications are not effective, then surgical treatment is required. Topical medication is a treatment method to eliminate axillary odor by applying various medications with antibacterial, astringent, antiperspirant, antiseptic and anti-odor effects to the armpits. 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 it is a topical medicine produced by regular manufacturers and approved by the state, those with mild symptoms can give it a try, but the claim of no more recurrence is not credible. Local injection is to inject alum liquid, anhydrous alcohol, and anti-hemorrhoid liquid into the bilateral axilla subcutaneously to produce sterile inflammation in the surrounding tissues and then adhesions, thus 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 after the injury heals. Freezing, laser, electrocoagulation and other methods are used to destroy the sweat glands by generating thermal effect or cold effect in the axillary hair area, so that the skin forms scar tissue and blocks the discharge of glandular secretion, thus achieving the purpose of treatment. The advantage of this method is that it is simple 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 armpit, 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, the phenomenon of relapse is more common in about three months. Question 4: I heard that axillary odor can only be completely treated through surgery, is it really so From the physiological anatomy, the sweat glands are located in the deep skin and fat layer, sweat ducts open in the upper third of the hair follicle, a few direct opening on the skin surface, axillary odor surgical treatment is through surgery, the destruction of human sweat glands or cut off the sweat ducts, to prevent the discharge of sweat, so that you can fundamentally achieve The purpose of getting rid of sweat odor. Therefore, the current method of complete treatment of armpit odor or surgical methods. The common 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 the healing, or scar contracture is formed after healing, and in serious cases, the upper arm is lifted 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 is unacceptable to many patients.
