What Causes Underarm Sweating?

Axillary sweating refers to the phenomenon of perspiration in the human armpit. There are two types of sweat glands in humans. One is small and is distributed throughout the body. Its main function is to wick away sweat and regulate body temperature. The other is a larger gland called the apocrine gland, which is located in special areas such as the axilla and genitals. Among them, the axillary is the most.

Axillary sweating refers to the phenomenon of perspiration in the human armpit. There are two types of sweat glands in humans. One is small and is distributed throughout the body. Its main function is to wick away sweat and regulate body temperature. The other is a larger gland called the apocrine gland, which is located in special areas such as the axilla and genitals. Among them, the axillary is the most.

The serous fluid secreted by the apical plasma glands was originally a odorless liquid, but it became an odorous liquid when it was decomposed by bacteria retained in the armpits, commonly known as fox-odor. Patients with sweaty underarms are prone to bacterial growth and have a particularly strong taste, which causes great distress in life.

Causes of axillary sweating

Hyperhidrosis is caused by excessive secretion of small sweat glands and manifests as abnormally excessive sweating throughout the body (generalized hyperhidrosis) or locally (localized hyperhidrosis). Hyperhidrosis can be secondary to certain mental and neurological diseases, metabolic diseases, endocrine disorders, tumors, drugs, etc., called secondary hyperhidrosis; the cause of primary hyperhidrosis is unknown, and the most common site is the palm , Armpits and soles of the feet, occasionally occur in the head and neck, trunk and lower legs. The age of onset is mostly from early childhood to adolescence and accompanied by life. When the illness is severe, it not only affects the patient's work, life and learning, but also causes the patient to have psychological disorders and dare not participate in normal social interaction. Local hyperhidrosis can be due to sympathetic nerve damage or abnormal response, increased choline acetate secretion, causing the small sweat glands to secrete excessive sweat.

The causes of hyperhidrosis can be roughly divided into three categories. First, it is caused by systemic diseases, such as endocrine disorders (hyperthyroidism, diabetes, pituitary hyperfunction, etc.), neurological diseases, some infectious diseases (malaria, tuberculosis, etc.) and chronic illness resulting in physical weakness. As long as these systemic diseases are under control, sweating can be resolved. The second is mental sweating, which is caused by high tension and emotional agitation, and is caused by sympathetic nervous disorders. Taking some sedatives (such as atropine, probencin, belladonna mixture, etc.) internally has temporary effects, but there are mouth Dry and other side effects. The third is taste sweating, which belongs to another physiological phenomenon, such as excessive sweating caused by eating certain irritating foods (chilli, garlic, ginger, cocoa, coffee). Generally, this condition does not need to be treated. .

Examination and diagnosis of axillary sweating

There is no uniform diagnostic standard for hyperhidrosis. In 2004, the American Dermatological Association John Hornberger organized a collaborative group consisting of experts from more than 20 units to develop a diagnostic reference standard.

The diagnosis can be confirmed if there is no obvious inducement that the sweat glands are hypersecretory for more than 6 months and meet the following conditions:

(1) Symmetrical sweating on both sides.

(2) at least once a week.

(3) The age of onset is less than 25 years.

(4) Have a positive family history.

(5) No sweating during sleep.

(6) Affect daily work life.

If accompanied by fever, night sweats, weight loss, attention should be paid to the possibility of secondary hyperhidrosis.

Differential symptoms of axillary sweating

1. Sweat sweat: Sweat sweat refers to sweat with odor. It is generally thought to be the result of sweat gland secretions and local bacterial work. (1) Clinical manifestations: stinky sweat can be divided into two types: general odor and local odor. Systemic stinky sweat: It is often a physiological phenomenon related to race. It can also be found in people with poor health habits. Taking certain foods such as onions, garlic, mustard or certain drugs such as musk can produce in some people. Sweat. Localized stinky sweating; mainly occurs in the underarms, feet, and perineum, manifested as sweaty and odorous, with the most common underarm odor. The smell of stinky sweat is different, most of which are related to hyperhidrosis, which is aggravated in summer, with the strongest odor during adolescence, which decreases with age.

2. Hand, foot, and hyperhidrosis: often limited to palms and palms, some patients still have axillary hyperhidrosis, usually first in children or adolescence, both men and women can develop the disease, most of which last for several years, some patients may naturally reduce after 25 years of age . Sweat can drip continuously during the onset of the disease, especially during periods of stress, agitation, terror, anxiety, or anger. Sweating can be continuous or intermittent. If it is continuous, the emotional factors are not important. If it is intermittent, it may be caused by anxiety, stress or fear. Hand, foot and hyperhidrosis is mostly caused by abnormal hyperactivity of sympathetic nerves. It is characterized by sweaty hands and feet, and wet hands and feet as a whole. Although it has no direct impact on health, it seriously affects learning, socializing, and work. Some cases may have a family genetic history.

3. Menopausal hyperhidrosis: Paroxysmal hyperhidrosis in women's menopause syndrome has brought a lot of annoyance to patients. Clinically, the prescription prescription walnut nut treatment was used to obtain good results. The method is to use full, nut-free, nutrient-free walnut kernels, with two layers of yellow skin, and chew 4-5 mornings and evenings each day. Generally, it can take effect for 5-7 days, and it can be cured in 15-30 days. .

There is no uniform diagnostic standard for hyperhidrosis. In 2004, the American Dermatological Association John Hornberger organized a collaborative group consisting of experts from more than 20 units to develop a diagnostic reference standard. The diagnosis can be confirmed if there is no obvious inducement that the sweat glands are hypersecretory for more than 6 months and meet the following conditions:

(2) at least once a week.

(3) The age of onset is less than 25 years.

(4) Have a positive family history.

(5) No sweating during sleep.

(6) Affect daily work life.

If accompanied by fever, night sweats, weight loss, attention should be paid to the possibility of secondary hyperhidrosis.

Prognosis of axillary sweating

Keep the area clean and remove the secretions to reduce the proliferation of bacteria. Use local antiperspirant fragrances. Regular scrubbing and rubbing can relieve the odor temporarily. Actively treat primary disease. "Symptoms and Disorders of Treating Sweat": Shaoyang's fever, hellip; hellip; It should be noted that when venting from the interaction between yin and yang, and those who vented from the yin and yang interaction, both yin and yang are not equal to half surface and half syria, and Xiaochaihu decoction and Xiaoyao San are also mixtures.
