In our country, the problem of fatty liver and steatohepatitis is becoming more and more prominent due to economic development and improvement of people’s living standards. A significant proportion of my daily outpatients are patients with fatty liver disease. Before diagnosing fatty liver or steatohepatitis, other common chronic liver diseases must be ruled out. In our country, especially chronic hepatitis B needs to be ruled out, which can be done by performing a hepatitis B two-to-one test. In addition, to rule out chronic hepatitis C, an anti-HCV test is required. For fatty liver, the key to treatment is to lose weight. Weight loss includes diet control and exercise. Diet control includes: control the amount of diet, only about 7 layers full per meal; control high cholesterol food and greasy food, such as fatty meat, animal offal, shelled seafood; abstain from alcohol. Exercise should be done daily, with emphasis on moderate intensity, at least half an hour to an hour a day, and be consistent! If there is steatohepatitis, i.e. on top of simple fatty liver, there is also elevated transaminases, in addition to the above-mentioned dietary control and exercise, medication is also needed. Because steatohepatitis can also gradually develop into liver cirrhosis and liver cancer, it needs to be given high priority.
