How to regulate abnormal sweat gland secretion

Different physiques reflect different conditions. Many people change clothes twice a day in summer because their sweat glands are very developed and they sweat severely when the temperature is high. Many women want to improve the problem of sweating easily. How to regulate abnormal sweat gland secretion? Here we will introduce to you the causes of abnormal sweating.

1. What are the causes of abnormal sweating?

1. Eccrine sweat glands There are 2 to 5 million eccrine sweat glands in adult skin, with an average of 143 to 339 per square centimeter. The palms and soles of the feet have the most, with about 620 per square centimeter, while the thighs have the least, with only 120 per square centimeter. The activity of the eccrine sweat glands is controlled by the sympathetic nervous system, mainly choleretic fibers. Experiments have shown that local injection of choline acetate can cause the eccrine glands to secrete large amounts of sweat. Local injection of epinephrine can also cause increased secretion of sweat glands and the discharge of a small amount of sweat. The secretion of sweat glands in normal people is obviously related to temperature, amount of exercise and mental factors. Sweat is composed of 99% water and 1% solid. The largest organic substances are urea and lactic acid. The largest inorganic substance is sodium chloride, in addition to calcium, magnesium, phosphorus, and benzene. Sweat also contains a variety of amino acids. The relative density of sweat is 1.001~1.006 and the pH is 5.5+0.5. Factors that affect the secretion of eccrine sweat glands include: ① temperature; ② mental factors; ③ medications such as aspirin; ④ diet such as eating spicy food and drinking hot soup; ⑤ diseases such as night sweats caused by tuberculosis.

2. The apocrine sweat glands have two excretion pathways, one opening in the hair follicles and the other opening in the skin. The components of sweat are water and solid components including iron, odorous substances, and colored substances such as yellow, brown, green, cyan, red, and black. Can form colored sweat in the armpits. Sweat glands also dissipate heat, regulate body temperature, moisturize the skin, remove drugs and metabolites to reduce the burden on kidney function.

2. Congenital hereditary

1. Congenital ectodermal dysplasia anhidrosis.

2. Riley-Day syndrome (Sjögren's syndrome due to dehydration) is an autosomal recessive trait. It is accompanied by hyperhidrosis.

3. Spanlang Tappeiner syndrome (hair loss, hyperhidrosis. Tongue-shaped corneal opacity syndrome is an autosomal dominant inheritance.

3. Mental and neurological damage factors

1. Hyperhidrosis is caused by mental stress, emotional excitement, and nervous stimulation.

2. Psychological factors are an important cause of dyshidrotic eczema.

3. Rhinitis may be a vasomotor nerve disorder.

4. Causes of Disease

1. Night sweats are common in patients with pulmonary tuberculosis.

2. Sjögren's syndrome with generalized anhidrosis.

3. Local anhidrosis is seen in congenital ichthyosis; systemic scleroderma; leprosy; chronic radiation dermatitis; transverse myelitis; and syringomyelia.

4. Hemathidrosis is seen in hemophilia and plague.

5. Drug-induced chromhidrosis

Injecting methylene blue can make sweat blue, taking iodide can make sweat light red, and taking chloropheniramine internally can make sweat red.

6. The mixture of bacteria and organic substances in sweat

For example, bromhidrosis is often seen in the apocrine sweat glands in the armpits.

7. Urea sweat.
