The most effective treatment for smelly feet in 10-year-old children does not exist. Foot odor can be caused either by physiological factors or due to certain pathological factors, and in some patients there is a family genetic history. Treatment includes general therapy and medication. 1. Physiological factors: human feet have a lot of sweat glands, easy to sweat, but foot sweat itself does not have odor. When the foot movement is large, the foot sweat increases, the warm and moist environment in the shoes is conducive to the growth and reproduction of bacteria and molds, which produces an unpleasant odor. At this time, let the children wash their feet diligently, change shoes and socks, and try to wear cotton socks as well as breathable shoes, which can improve the odor of the feet. 2. Pathological factors: tinea pedis (commonly known as foot fungus) is the most common, when a fungal infection occurs in the foot, the fungus can break down the local keratinocytes, resulting in the formation of an abnormal odor, the main is to take local antifungal medication, such as ketoconazole cream, miconazole cream and so on. 10-year-old children’s foot odor if the symptoms are more serious, especially when it leads to itchy feet, should be timely to the hospital dermatology department, with the doctor standardized treatment.
