Foot odor is part of body odor and can be caused by a variety of factors, including the patient’s physiological factors, disease factors. Only by first clarifying the causes of foot odor can we develop a suitable treatment plan. First, the cause 1, physiological factors: for example, due to emotional stress or after strenuous exercise, the patient’s feet themselves sweat more, creating a moist environment, conducive to sweat fermentation, breeding a large number of bacteria, mold, thus producing foot odor. If you do not pay attention to their own personal hygiene, do not often wash their feet, cut toenails, too thick old keratin and dead skin, also easy to produce foot odor. In addition, if patients wear non-breathable shoes, polyester, nylon socks for a long time, can lead to increased foot sweating, rapid growth of bacteria, triggering foot odor; 2, disease causes: patients themselves have tinea pedis, which can cause foot odor symptoms. If the patient has foot hyperhidrosis, sweat glands are more excitable, resulting in more sweaty feet, which can cause foot odor phenomenon. Second, treatment 1, topical drugs: patients are advised to visit a hospital, under the guidance of a doctor, to do a fungal examination of the skin of the foot and develop a treatment plan. Alum solution, formaldehyde solution, potassium permanganate solution can be used to play the effect of astringent anti-sweat, sterilization and deodorization; 2, oral medication: under the diagnosis of a professional doctor, if the patient’s foot odor is caused by disease factors, in addition to the application of ketoconazole ointment, nitromycin ointment and other drugs, but also oral itraconazole capsules and other drugs. In life, it is recommended that patients try to choose shoes and socks with better breathability to avoid providing an environment for bacteria to breed and eliminate foot odor. In addition, patients should pay attention to personal hygiene and relieve foot odor by soaking their feet every day. You can also use aromatherapy and deodorant to neutralize foot odor or absorb foot odor.
