Hyperhidrosis is a condition in which the sympathetic nerves are overexcited or highly stressed, causing excessive sweat secretion. The sympathetic nerve governs sweating throughout the body. Normally, the sympathetic nerve regulates body temperature by controlling sweating and heat dissipation, but the sweating and facial flushing of patients with hyperhidrosis completely lose their normal control, leaving patients in a state of helplessness, agitation or panic on a daily basis. The causes are 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. The following diseases are the causes of high sympathetic nervousness: 1, malaria Malaria is caused by the bite of Anopheles mosquitoes or the input of blood with Plasmodium parasites and infected with Plasmodium parasites caused by insect-borne infections. There are four kinds of Plasmodium parasites in human body, namely Plasmodium intergenerum, Plasmodium trisporus, Plasmodium falciparum and Plasmodium ovale. In China, the main parasites are Plasmodium vivax and Plasmodium falciparum; the other two species are rare, and some cases imported from abroad are occasionally seen in recent years. Different Plasmodium parasites cause Plasmodium vivax, Plasmodium trisomy 21, Plasmodium falciparum and Plasmodium ovale respectively. The disease is mainly manifested as periodic regular attacks, generalized chills, fever, and excessive sweating, which can cause anemia and splenomegaly after many long-term attacks. Hyperhidrosis is a disease caused by excessive secretion of sweat glands due to excessive excitation of sympathetic nerves. The sympathetic nerve governs sweating throughout the body. Under normal circumstances, the sympathetic nerve regulates the body temperature by controlling sweating and heat dissipation. In hyperhidrosis, however, sweating and facial flushing are completely out of control. The excessive sweating and facial flushing leave the patient in a daily state of helplessness, agitation or panic. 3. Cortical hyperhidrosis Cortical hyperhidrosis is a type of hyperhidrosis in which excessive sweating is associated with cortical activity. This includes emotional hyperhidrosis, palmoplantar hyperhidrosis, axillary hyperhidrosis, and other disorders with cortical hyperhidrosis. 4, medullary hyperhidrosis medullary hyperhidrosis (medullary hyperhidrosis) because the efferent stimulus often involves taste receptors, so medullary hyperhidrosis is also known as gustatory sweating (gustatory sweating), can be divided into two types of physiological and pathological medullary hyperhidrosis. 5, diabetes mellitus (diabetes) is a series of metabolic disorders such as sugar, protein, fat, water and electrolyte syndrome caused by genetic factors, immune dysfunction, microbial infection and its toxins, free radical toxins, mental factors and other pathogenic factors acting on the body, resulting in hypoglycemia, insulin resistance, etc. Clinically, hyperglycemia is the main feature, and typical cases can appear Diabetes mellitus (blood glucose), once poorly controlled, can lead to complications, resulting in kidney, eye, foot and other parts of the failure of the lesion, and can not be cured.
