Excessive sweating is due to sympathetic over-excitement caused by excessive secretion of sweat glands of a disease. Under normal circumstances sympathetic control of sweating through the heat to regulate body temperature. However, patients with hyperhidrosis sweating and facial flushing completely lost the normal control, sweating and facial flushing make patients feel a daily frustration, irritability, or panic.
What causes excessive sweating? Generalized hyperhidrosis may be an abnormal physiological response, or certain diseases such as hyperthyroidism, diabetes. Local hyperhidrosis may be due to injury or abnormal sympathetic response to acetylcholine secretion increased, leading to excessive secretion of eccrine sweat. From the incidence of causes of excessive sweating can be broadly classified into three categories.
First, as a result of systemic diseases, such as endocrine disorders (hyperthyroidism, diabetes, pituitary hyperthyroidism, etc.), nervous system diseases, some infectious diseases (malaria, tuberculosis, etc.) and long-term illness caused by physical weakness. As long as these systemic diseases are controlled the situation after the hyperhidrosis can be resolved.
Second, the spirit of sweating, due to a high degree of tension and emotion caused because the sympathetic nervous disorder and the oral administration of some sedative drugs (such as atropine, Propantheline, belladonna mixture, etc.) have a temporary effect, but there are side effects such as dry mouth.
Third, the taste of sweat, and belongs to a different physiological phenomena, such as to eat some spicy food (chili, garlic, ginger, cocoa, coffee) caused by hyperhidrosis after, this is rarely necessary to carry out treatment, only stop eating those foods.
