Armpit odor, also known as fox odor, is considered to be related to heredity and environmental factors, and can be treated by general treatment, medication and surgery to alleviate the patient’s symptoms. 1. General treatment: patients should take bath frequently and change clothes to keep the armpit area dry and clean. It is better to shave off the armpit hair, which can reduce the number of local parasitic bacteria; if necessary, it can also be used with antiperspirant. 2. Medication: For mild to moderate cases of bad odor, injection of botulinum toxin type A under the armpits can significantly inhibit the phenomenon of bad odor, but the maintenance time is not long, and repeated injections are required. 3. Surgical treatment: for patients with moderate-to-severe body odor, small incision minimally invasive sweat gland removal surgery can be chosen, which is more effective and less likely to be repeated. After the diagnosis of armpit odor, patients should combine with their own situation, cooperate with the doctor to give targeted treatment and therapy.
