Axillary odor, also known as smelly sweat, means that the secreted sweat has a special smell or the sweat decomposes to produce a bad smell. If it is light, there is no need for treatment. Take a bath frequently, change clothes and socks frequently, and keep parts clean and dry. Hyperhidrosis patients are mainly treated locally, such as local wet compress or soaking in 20%-25% aluminum chloride solution, 1% povidone iodine solution, 1: 8000 potassium permanganate solution or 0.5% neomycin solution, which can sterilize and deodorize. Patients with severe bromhidrosis can choose laser or surgery, and the cure rate of surgery is also high, but it is easy to leave scars after invasive treatment, and the recovery is relatively slow. Laser treatment is minimally invasive, and it is not easy to leave scars after operation, but the cure rate is relatively low. .
