The main consideration for not sweating in the armpits, but having an odor, is that it is related to bad breath. Fox odor, also known as stinky sweat, is a skin disease that produces an unpleasant odor by the secretion of sweat from the top secretory sweat glands in the armpits by the bacterial decomposition of the skin. The etiology of bad breath is not yet clear, may have a certain relationship with heredity, mostly because of bacterial decomposition of sweat odor, perianal, umbilical and other parts of the corresponding odor can also appear, some patients may appear in the external auditory canal of the soft earwax. Fox odor patients usually show that when they do not sweat, the smell is not heavy; when the weather is hot and sweat a lot, the smell is usually heavier. Therefore, when the armpits are not sweating, the odor may be localized as well. Odorant sweating usually does not affect physical health, but it can increase psychological burden and lead to psychological stress. If the patient has increased sweating without exercise or emotional stress, it is recommended to visit a hospital dermatologist. Antiperspirants, deodorants, local injections of botulinum toxin or surgery can be given in conjunction with the doctor’s advice.
