The cause of axillary odor is abnormal function of the sweat glands, which in most cases are inherited from one parent. The sweat gland is present in childhood, but its function of driving to secrete odor is stimulated by sex hormones, so it usually does not develop until puberty, when surgical treatment can be performed. Some children develop a stronger odor before puberty, in which case there is no need to wait until puberty to undergo surgery. The youngest armpit odor patient I have done is 8 years old with heavy symptoms and no signs of recurrence even after 3 years of postoperative follow-up. Therefore, it is said that the recurrence of axillary odor is not related to age, but to the surgeon’s surgical skills, and the key is to remove the sweat glands to a sufficient depth and extent. It is not correct to say that surgery at too young an age will lead to recurrence due to the growth of new sweat glands as we grow older. Therefore, the best time for armpit odor surgery is when the odor appears and affects your social and self-image (usually after puberty), not when you have to wait until adulthood.
