Hypoglycemia occurs when the blood glucose concentration is less than 2.8 mmol/L in normal people and less than 3.9 mmol/L in diabetic patients. Patients often experience symptoms of panic, accompanied by cold sweats, hunger, trembling hands, dizziness, and in more severe cases, psychiatric symptoms, delirium and epilepsy. In addition to hypoglycemia, cardiac conditions such as diffuse goiter with hyperthyroidism, hypermetabolic syndrome, viral myocarditis, cardiomyopathy, hypertensive heart disease, etc., can also cause panic, so patients should pay attention to differentiate. If the panic is caused by hypoglycemia, the common causes are: 1, insufficient intake: prolonged fasting, dieting, gastrointestinal dyspepsia and other causes of insufficient intake; 2, catabolic disorders: liver disease, glycogen storage disease and other diseases, resulting in hepatic glycogen decomposition disorders or glycogen decomposition disorders; 3, overconsumption: strenuous physical activity, renal diabetes mellitus and other causes of excessive consumption of sugar; 4, conversion of too much: hypoglycemic drugs Excessive use of glucose-lowering drugs or insulinoma causes excessive sugar conversion. After the occurrence of hypoglycemia, patients should replenish sugar in time, can drink sugar water, if necessary, intravenous infusion of glucose.
