πŸ‘‰What is underarm odorπŸ‘ˆ

Underarm odor, commonly known as “body odor”, is a common disease produced by the axillary apocrine glands, which is decomposed by bacteria after being excreted from the body to produce an unpleasant odor. This disease affects patients’ daily communication and causes their psychological burden.

Broadly speaking, underarm odor is divided into simple underarm odor and underarm bromhidrosis. In addition to underarm odor, the latter also has hypersecretion of axillary eccrine glands and increased local sweat secretion, that is, symptoms of hyperhidrosis. Due to the coexistence of large and small sweat glands in the armpits, the excessive secretion of eccrine glands leads to hyperhidrosis, and the decomposition of apocrine secretions leads to underarm odor.

Studies have shown that most patients with underarm odor have a family history and a history of oily ear cerumen; underarm odor often occurs in adolescence, and this odor will gradually disappear or decrease with aging. The ratio of male to female is 1:1.4. According to the survey, the incidence rate can reach 6.41% in our country. Severe underarm odor can seriously affect the work and life of patients, and even cause depression.


1. Sex hormone levels

Patients with underarm odor usually have no obvious odor from birth to puberty. With the arrival of puberty, the development of the sex glands and the increase of hormone levels, patients with underarm odor begin to emit unpleasant odors. With age, the odor will gradually subside. This phenomenon suggests Hormones are related to underarm odor.

2. Neural factors

Both apocrine sweat glands and eccrine glands are innervated by nerves. Under the action of mental factors, the sympathetic nerves are excited to innervate the apocrine sweat glands to secrete more metabolites. At the same time, the eccrine glands secrete a lot of sweat, which makes the armpits moist and provides for the growth of bacteria in the armpits. Good environment; the sweat in the armpits can dissolve the secretions of the apocrine sweat glands, so that the metabolites are more fully in contact with the bacteria in the armpits. The two complement each other and increase the axillary odor.

Three, genetic factors

A large number of studies have found that the ABCC11 gene is related to the pathogenesis of underarm odor.

Fourth, the level of microorganisms in the armpits

The microbial density in the armpits of patients with underarm odor was significantly higher than that of patients with non-underarm odor.

πŸ‘‰Severity of underarm odorπŸ‘ˆ

Level 0: No smell can be smelled under any circumstances.

Level 1: After strenuous activity, only one can smell a slight odor.

Level 2: After light activity, a strong odor can be smelled, but only within 30cm.

Level 3: In the resting state, a strong odor can be smelled, and it can also be smelled beyond 30cm.

πŸ‘‰How to treatπŸ‘ˆ

Common treatment methods include the use of non-surgical methods such as topical drugs, local injections, local botulinum toxin treatment, high-frequency electroacupuncture, laser treatment, iodine ion, microwave treatment and other non-surgical methods. Surgery includes axillary skin resection method, subcutaneous trimming method, swelling anesthesia suction and scraping method, and thick and medium thickness skin in situ skin grafting along the axillary line incision.

The above treatment methods have their own advantages and disadvantages. The specific treatment method depends on the severity of underarm odor and the communication with the doctor.
