Armpit odor does not always require surgery, but can also be relieved by improving local hygiene, using deodorants, and medication. Armpit odor is due to the decomposition of sweat excreted by the sweat glands in the armpit, by bacteria on the surface of the skin, mainly staphylococcus, which produces unsaturated fatty acids, resulting in a foul odor, mostly seen in young adults. If the patient’s condition is mild, bathe regularly, change clothes regularly and keep the underarm clean, the symptoms may be relatively insignificant and do not affect daily life. Some patients can also use some antibiotic ointment to inhibit the epidermal bacteria in the armpit area to relieve the symptoms, while using deodorant to cover up. However, patients with severe armpit odor can only consider surgical treatment to completely cure armpit odor by surgically removing the sweat glands or cauterizing them with laser. Patients should usually avoid spicy and irritating foods, especially curry and pepper, etc. After surgery, they should take care of the wound and not get wet to prevent infection.
