The following 3 conditions can easily lead to hepatitis: 1, long-term drinking, the main component of alcohol is ethanol, 90% ethanol is metabolized in the liver, after metabolism into acetaldehyde can be combined with protein in the liver, the formation of acetaldehyde protein conjugate, there is a significant toxic effect on liver cells, so drinking can lead to hepatitis. 2, often long and strenuous exercise, such as running marathons or running 10 km per day. Such intensity of exercise, such as half a month in a row, will also have an impact on the liver. The liver is in a state of ischemia and hypoxia, which can easily cause liver function abnormalities. 3, staying up late has a great impact on the liver, which is a detoxification organ, and most of the detoxification and detoxification work is carried out in the second half of the night, and staying up late for a long time can easily lead to slower excretion of toxins and accumulation of toxins, which can easily induce hepatitis.
