Patients can protect their liver health through diet, exercise and sleep. 1. Diet: Excessive intake of sugars, proteins or lipids beyond the normal range can put a strain on the liver and lead to diseases such as fatty liver over time. Alcohol is an important factor in the formation of many liver diseases, such as alcoholic liver disease and cirrhosis. Therefore, patients need to stop drinking or eliminate alcoholic beverages, eat less or no greasy, fried foods, cream, egg yolks and other high-fat, high-cholesterol foods. 2. Exercise: Usually, appropriate exercise helps to reduce blood lipids and the burden on the liver. 3. Sleep: Generally speaking, patients should go to bed early and get up early, do not stay up late, and avoid fatigue, which can help the liver fully recover its physiological functions. If patients have liver function problems, they should actively seek medical treatment to avoid delaying their condition.
