High fatty liver is associated with obesity, alcohol consumption, rapid weight loss, diabetes, infections and other factors. There are more reasons for the formation of fatty liver, commonly due to the factor of obesity. Fat in the liver is directly proportional to body weight, when the body is too obese the liver area will also accumulate fat, so about 30%-50% of obese patients are easy to combine fatty liver. Alcohol damage to liver cells is relatively large, after drinking alcohol, more than 90% of alcohol metabolism is completed from the liver cells, so it is easy to lead to the deposition of fat in the liver cells, the formation of fatty liver. People who lose weight quickly will need to break down a lot of fat in a short period of time through dieting and fasting, so it is easy for liver cells to degenerate and lead to fatty liver. About 50% of diabetic patients may have fatty liver, and after suffering from hepatitis B, they will restrict their activities and often eat high sugar and high calorie food in their diet, which leads to the accumulation of fat in the liver cells, which is also a factor that induces fatty liver.
