Patients with underarm odor may be due to the secretion of sweat from the underarm sweat glands, which is decomposed by local bacteria and produces a pungent odor. It is recommended that patients should increase the frequency of underarm cleaning and always keep the underarms dry, which has a certain effect on relieving underarm odor. In addition, patients can also consider using topical drugs, injection therapy or surgical treatment to relieve the symptoms of axillary odor: 1. Topical drugs: Patients can consider spraying some disinfectants in the armpits, such as aluminum chloride solution, povidone iodine solution, etc., which can get rid of some of the bacteria in the armpits and relieve the symptoms of axillary odor. In addition, patients can also apply some items with antiperspirant effect in the armpits, such as zinc oxide ointment, antiperspirant beads, antiperspirant lotion, etc. to reduce the secretion of sweat, thereby reducing the underarm odor. Because it cannot completely destroy the sweat glands, it can only play the role of temporary relief, so such methods are more suitable for patients with mild armpit odor; 2, injection therapy: patients can choose to carry out injections of botulinum toxin, thereby reducing the symptoms of underarm odor to some extent, but usually need to repeat the treatment several times; 3, surgical treatment: small incision scratching method and large sweat gland trimming method are common clinical surgical methods. When taking the small incision scratch method of treatment, the patient’s surgical incision is smaller, faster recovery after surgery, the local scar is smaller after surgery, but easy to recur. In the case of the large sweat gland trimming method, the surgical incision is relatively large, but the removal effect is better and the treatment is more effective. Patients with underarm odor should pay attention to personal hygiene, bathe regularly, change clothes regularly, and it is recommended to wear breathable cotton-type clothes so as to relieve underarm humidity, avoid bacterial growth and reduce the symptoms of underarm odor.
