There are a variety of surgical and non-surgical treatments available for the treatment of armpit odor. Whether or not it recurs and how often it recurs is related to the surgical method and the effectiveness of the treatment, as well as the patient’s condition, so there is no generalization. Halitosis is a skin disease in which the sweat excreted by the sweat glands in the patient’s armpits is broken down by bacteria on the skin surface, producing unsaturated fatty acids and a special pungent odor. The odor is usually more pronounced when sweating from exercise, hot weather and perspiration. The disease is usually treated with surgery and usually does not recur. Some patients may have missed treatment after surgery, and it is difficult to completely remove the sweat glands deep in the dermis. When the tissues return to normal, the sweat glands in the armpits may also be produced again, so patients may also suffer from recurrence, but the time of recurrence cannot be generalized. It is recommended that patients pay attention to reducing exercise and eating less spicy food in their daily life so as not to stimulate the sweat glands to over-secrete sweat, and keep the skin in the armpit area clean, dry and prevent infection.
