Fox odor is getting worse and worse may be due to the lack of attention to personal hygiene or aggravation of the condition, which needs to be timely to the hospital for consultation and active treatment. The exact pathogenesis of halitosis is not clear, and it is generally believed that the odor may be related to a variety of factors, such as insufficient cleansing, consumption of irritating foods, hot weather and so on. The aggravation of the fox odor may be caused by insufficient cleaning of the armpits, or it may be a manifestation of the seriousness of the condition. Patients first need to pay attention to cleanliness and hygiene, showering and changing clothes frequently to keep the armpits dry and clean. Armpit hair can be removed and antiperspirant can be used locally. In serious cases, the patient can be treated with drugs such as trichlorodiphenylurea and zinc oxide nylon powder under the guidance of medical professionals, or local botulinum toxin injections, surgery or physical therapy. If the above situation occurs, it is recommended to go to the hospital in time, and the medication should be used according to the doctor’s prescription.
