General treatment: change clothes and take baths regularly to keep the armpits clean and tidy to avoid bacterial growth. 2. Botulinum toxin injection: Botulinum toxin A injection blocks the peripheral cholinergic nerve endings and inhibits the release of acetylcholine, which can reduce the secretion of sweat, thus relieving armpit odor. 3. Surgical treatment: suitable for more serious armpit odor, through the removal of most of the top secretion sweat glands to achieve the therapeutic purpose, belongs to the better therapeutic effect of the method. If there is a need to treat armpit odor, it is recommended to go to the regular hospital in time, under the guidance of the doctor.
