First, the early symptoms and manifestations of hepatitis: such as: loss of appetite, poor digestive function, abdominal distension after eating, no hunger; Hate to eat greasy food, if you eat it, it will cause nausea and vomiting, and you will be susceptible to fatigue after activities. 1. Have loss of appetite, don't want to eat, and have a bad appetite; 2. The face is dark, yellow and brown, rough, and the lip color is dark purple; 3. The sclera or skin is yellow, or there are three yellow symptoms; 4. There is dull pain and swelling in the liver area; 5. Spider nevus and liver palm symptoms appear. Second, people who are prone to hepatitis 1, obese people. Obese people's subcutaneous adipose tissue decomposes fat, resulting in fat deposition in the liver. 2. Alcoholics. Alcohol is catabolized in the liver, which can lead to obstacles in the decomposition and metabolism of fatty acids. Therefore, the more alcohol you drink, the easier it is for fatty acids in the liver to accumulate, and the easier it is to lead to alcoholic fatty liver. 3. Older people. With the increase of age, people's metabolic function gradually declines, the amount of exercise decreases, and the probability of fat deposition increases. At the same time, middle-aged and elderly people suffer from endocrine diseases, such as diabetes, which can cause metabolic disorders and eventually make fat accumulate in the liver. 4. Those who like meat. Many young people often have family gatherings and banquets with friends. Eating too much high-fat food will increase the burden on the liver, and the intake and synthesis of fat by the liver will increase, or the transportation and utilization will decrease, which will lead to the accumulation of fat in the liver. 5, less active. Long-term inactivity leads to the transformation of excess nutrients into fat. When these fats are deposited under the skin, they show obesity, and when they are accumulated in the liver, they show fatty liver. 6. Hungry people. People who are often hungry, due to the decrease of blood sugar, fatty acids in liver tissue are transferred into the blood, which increases the free fatty acids in the blood and can cause liver fat accumulation. 7. Malnourished people. Due to the lack of protein, the synthesis of very low density lipoprotein (VLDL) is reduced, which leads to the obstacle of triglyceride transport in the liver and the accumulation of fat in the liver. 8, hepatitis. Due to excessive food intake, decreased exercise and incomplete recovery of liver function, it is easy to cause fat accumulation in the liver.
