The most common reason is liver dysfunction. Alcohol is decomposed and metabolized in the liver, and if there is a serious lack or decrease of alcohol transaminase or ethanol dehydrogenase in the liver, it will lead to excessive accumulation of ethanol in the body, and easy drunkenness will occur. In addition, serious liver diseases, such as liver fibrosis, hepatic lobular hyperplasia, acute hepatitis, jaundice hepatitis, infectious hepatitis, hepatitis B, because of the decrease in liver secretion of aminotransferases will be easy to get drunk. 2, in the cardiac function is reduced, will also be very easy to get drunk, for example, coronary artery atherosclerotic heart disease, heart failure patients peripheral compensatory capacity and detoxification ability, will relatively weakened will be easy to get drunk. For example, coronary artery atherosclerosis heart disease, heart failure patients’ peripheral compensatory ability and detoxification ability will be relatively weakened and easy to get drunk. 3, chronic hypertension, diabetes mellitus and cerebrovascular disease patients are especially prone to drunkenness, the body’s blood running state is poor, the liver’s detoxification and metabolism function will be reduced. 4, lastly, the elderly body’s endocrine environment is disrupted and the basal metabolism rate is low is easy to get drunk.
