High sympathetic tension is one of the symptoms of hyperhidrosis, a disorder in which excessive sweating is caused by overexcitation of the sympathetic nerves or high tension. The sympathetic nerve governs sweating throughout the body. Normally, the sympathetic nerve regulates body temperature by controlling sweating and heat dissipation, but the patient’s sweating and facial flushing are completely out of normal control, and the excessive sweating and facial flushing leave the patient in a state of helplessness, agitation or panic on a daily basis. Its etiology is broadly divided into three categories, one is due to systemic diseases, the second is psychogenic sweating, and the third is gustatory sweating, which is another physiological phenomenon. Systemic hyperhidrosis can be an abnormal physiological response or one of the symptoms of certain diseases such as hyperthyroidism and diabetes mellitus. Localized hyperhidrosis can be due to sympathetic nerve damage or an abnormal response with increased secretion of choline acetate, resulting in excessive sweat secretion from small sweat glands. I. Pathogenesis Hyperhidrosis can be broadly divided into three categories from the pathogenesis. One is due to systemic diseases, such as endocrine disorders (hyperthyroidism, diabetes, hyperpituitarism, etc.), neurological diseases, some infectious diseases (malaria, tuberculosis, etc.) and weakness due to long-term illness. As soon as these systemic diseases are controlled the excessive sweating can be resolved. The second is psychogenic sweating, caused by high tension and emotional excitement, is due to sympathetic dysregulation. Taking some sedative drugs internally (such as atropine, probenecid, belladonna combination, etc.) has a temporary effect, but has side effects such as dry mouth. The third is gustatory sweating, which is another physiological phenomenon, such as excessive sweating caused by eating certain stimulating foods (chili, garlic, ginger, cocoa, coffee), which generally does not need to be treated and must only be avoided. Second, the pathogenesis of hyperhidrosis mainly refers to excessive sweating in multiple parts of the small sweat glands, often involving the axillae, palmoplantar and groin, the cause can be divided into neurogenic and non-neurogenic, neurogenic refers to the control of nerve reflexes; in addition to local thermal stimulation, non-neurogenic refers to the role of peripheral non-neurogenic factors – the excitatory response at the level of the glands .
