Hyperhidrosis is a condition in which the sympathetic nerves are overexcited or highly stressed, causing excessive sweat secretion. Under normal circumstances, the sympathetic nerve regulates body temperature by controlling sweating and heat dissipation, but in patients with hyperhidrosis, sweating and facial flushing are completely out of control, leaving the patient in a state of helplessness, agitation or panic. The diagnosis of hyperhidrosis-induced sweating relies on a combination of laboratory tests, imaging tests and autonomic function tests in addition to the typical sweating manifestations. The history of high sympathetic nervousness should include detailed questions about the causes of abnormal sweating before it occurs. For example, whether there is mental tension, emotional excitement, history of neurotrauma, medication and disease. For example, hemophilia can cause hematochezia, and chlorpheniramine can cause redness of sweat. Ask if there are similar patients in your family to exclude genetic factors. There are no better measures for high sympathetic nervousness, but the main thing is to prevent related diseases. If there is a genetic syndrome background, preventive measures include the introduction of genetic counseling, carrier genetic testing and prenatal diagnosis and selective abortion to prevent the birth of affected children. Relaxation, attention to personal hygiene, frequent bathing and changing of clothes. The disease can be cured after controlling the primary lesion or predisposing factors, but it is prone to recurrence. Prompt medical attention should be sought.
