Hyperhidrosis

Introduction Hyperhidrosis is a disease caused by excessive secretion of sweat glands due to excessive sympathetic stimulation. Sympathetic innervation dominates the body's sweating. Under normal circumstances, the sympathetic nerve regulates the body's body temperature by controlling sweating, but the patient's sweating and facial flushing completely lose normal control. Hyperhidrosis and facial flushing make the patient daily. In helplessness, anxiety or panic.

Cause

The causes of hyperhidrosis can be generally divided into organic diseases and functional disorders. The former are mainly found in endocrine disorders and systemic diseases such as diabetes, hyperthyroidism, hypertension, hypertrophic pituitary function, congestive heart failure; nervous system Diseases such as concussion, hemiplegia, spinal trauma; tumors, such as metastatic tumor carcinoids; and infectious diseases such as malaria, tuberculosis and wave heat. Functional hyperhidrosis is generally caused by more mental sweating, such as high emotional stimuli, mental stress, horror, anxiety, pain, and anger.

Due to mental impairment or increased emotional impulses due to emotional impulses, acetylcholine secretion increases and hyperhidrosis; may also be due to increased sweat tension in the sweat glands, sympathetic disorders leading to hyperhidrosis, hyperhidrosis during menstruation, hyperhidrosis Can occur in some genetic syndromes.

Hyperhidrosis has two types: systemic and limited hyperhidrosis. Systemic hyperhidrosis can be an abnormal physiological reaction, or one of the symptoms of certain diseases such as hyperthyroidism and diabetes. The skin of a systemic hyperhidrosis is often moist and has paroxysmal sweating. Local hyperhidrosis can be caused by sympathetic nerve injury or abnormality, and increased secretion of choline acetate leads to excessive sweat secretion by the small sweat glands. Local hyperhidrosis is common in the palms, ankles, underarms, followed by the tip of the nose, forehead, genitals, etc., mostly in adolescents, patients often accompanied by peripheral blood circulation dysfunction, such as wet skin, bruising or pale, easy to produce frostbite Wait. The sweat in the foot is weak due to the evaporation of sweat, causing the skin of the sole to be whitened, often accompanied by foot odor. When the armpits and genitals are sweaty, the skin is thin and tender, often wet and rubbed, and it is prone to rubbing erythema, accompanied by folliculitis and phlegm.

According to the clinical manifestations, the characteristics of hyperhidrosis can be diagnosed.

Differential diagnosis

(1) Localized hyperhidrosis: It usually begins in children or adolescence. Both men and women can occur. Some have a family history and can last for several years. After 25 years of age, there is a tendency to naturally reduce. The most common sites of localized hyperhidrosis are palmar and rubbing surfaces such as underarms, groin, and perineum, followed by forehead nose and chest. The sweating of the palmar sputum is persistent or transient, caused by mood fluctuations. There is no seasonal difference. It often occurs when the hands and feet are cold or even sputum, and it can be accompanied by hand and foot keratosis. Sputum sweating can be induced by heat or mental activity, and excessive sweating is caused by excessive activity of small sweat glands, unlike odor, which is mainly caused by apocrine glands.

(2) Generalized hyperhidrosis: Mainly due to other diseases, widespread sweating, like infectious hyperthermia, due to regulation of the nervous system or oral antipyretic to sweat to dissipate heat. Other damages such as the central nervous system including the cortex and basal ganglia, the spinal cord or peripheral nerves can cause excessive sweating throughout the body. According to the clinical manifestations, the characteristics of hyperhidrosis can be diagnosed.
