Various liver diseases cause damage to the liver parenchyma and induce disorders of glucose metabolism, with clinical manifestations characterized by hyperglycemia and reduced glucose tolerance. This kind of diabetes mellitus secondary to liver parenchymal damage is called hepatic diabetes mellitus, which is type II diabetes mellitus. However, hepatic diabetes mellitus is different from type II diabetes mellitus. Its etiology has not been fully understood. The treatment should take into account both liver damage and diabetes. The principle is to treat the primary liver disease while keeping the blood sugar under control through modern comprehensive treatment. Therefore, doctors should clarify the treatment purpose of hepatic diabetes mellitus and the attainment standard of lowering blood glucose according to the characteristics of hepatic diabetes mellitus, so as to reasonably carry out comprehensive treatment. 1. Characteristics of hepatic diabetes mellitus: (1) The majority of patients are male, and the prevalence increases with age, half of them develop after one year of liver disease, and about 1/3 of the cases can develop at the same time; (2) It is often characterized by hyperglycemia and hyperinsulinemia, while the typical symptoms of diabetes mellitus, such as polydipsia, polyphagia and polyuria, are not obvious due to the influence of liver disease; (3) Most of the patients with mild disease can be treated by active liver protection and diet control, so that (3) Most patients with mild disease can normalize hyperglycemia and abnormal glucose tolerance through active liver protection and diet control, but patients with severe disease have a poor prognosis. (2) Clinical manifestations of hepatic diabetes mellitus: some are recessive, some are dominant, and the symptoms vary in severity, but the typical symptoms of “three more” are not obvious and are often masked by the symptoms of chronic liver disease, and complications such as ketoacidosis rarely occur. (1) Actively and reasonably treat liver disease and improve liver function by repairing liver cells. The purpose of education is to let patients have a preliminary understanding of the basic knowledge, characteristics, diet, drug therapy, self-monitoring and care of hepatic diabetes, and realize the lifelong and long-term nature of treatment, so that they can actively cooperate to achieve the best treatment effect; (3) Diet therapy, exercise therapy, etc., similar to ordinary diabetes, mildly elevated blood glucose through diet control and appropriate exercise to maintain normal blood glucose level; (4) Insulin therapy for hepatic diabetes: hepatic diabetes (5) Oral hypoglycemic drugs are an important means of diabetes treatment: most oral hypoglycemic drugs are metabolized in the liver and have certain damage to liver function, so drugs with light damage to the liver should be used under the guidance of a specialist, and liver function and blood glucose should be tested at the same time. For patients with liver cirrhosis, oral hypoglycemic drugs are not used as much as possible, and the treatment is with mobile island.
