Fox odor, or armpit odor, is a special pungent odor emitted from the sweat in the armpit area, often aggravated by hot weather or exercise. Usually, genetic fox odor cannot be completely cured, and can be relieved by general treatment, medication, surgery, etc. 1. General treatment: If the symptoms are mild and there is only a slight odor after exercise and exertion, it can be relieved by general treatment such as diligent changing of clothes and frequent bathing. In daily life, spicy and stimulating foods should be avoided to avoid aggravating the symptoms; 2. Medication: topical medications such as antibacterial agents, antiperspirants and deodorants can be applied to the armpits, or sclerosing agents such as alcohol, sodium cod liver oil and urea can be injected in the skin of the armpits under the operation of a professional doctor to make the sweat glands shrink and the ducts occlude, so as to relieve fox odor. Botox can also be used for underarm injections to reduce sweat gland secretion by blocking the nerve conduction. However, it should be noted that this method requires regular and repeated injections as prescribed by the doctor; 3. Surgery: In clinical practice, those with more severe symptoms can surgically destroy the sweat glands in the armpit area to make them lose their function of sweat secretion, thus achieving the purpose of treating fox odor, but the sweat glands are deep and shallow, so it is impossible to ensure 100% destruction and there is a possibility of recurrence, thus preventing complete cure.
