Clinically, it is often seen that improper diet causes liver disease patients to aggravate their existing liver diseases and even develop serious complications such as gastrointestinal hemorrhage and hepatic encephalopathy. Therefore, it is very important for liver disease patients to have reasonable dietary treatment. 1.All patients with liver disease should abstain from eating alcoholic beverages. 2, acute hepatitis: should supply high protein, high carbohydrate, moderate fat (about 10% ~ 20% of the total calories), light, easy to digest, less flatulence food. Depending on the condition, semi-liquid, soft rice or general food can be used, and the food should be supplied with multi-vitamins. 3, cirrhosis: should supply high protein, high carbohydrate and sufficient vitamins, easy to digest food. Patients with ascites or edema should be supplied with less salt or salt-free diet. When blood ammonia is high, protein intake should be limited. Patients with esophageal varices should be given liquid or soft food, and coarse fiber and food with bone spurs should be prohibited. Those with biliary cirrhosis should be given low-fat and low-cholesterol diet. 4.Hepatic encephalopathy: low protein, low salt, high carbohydrate, high vitamin less residue, semi-fluid or fluid should be given. The intake of protein in the diet should be decided at discretion. If the blood ammonia increases without neurological symptoms, low protein can be given (about 0.5 grams per kilogram of body weight per day); if there are neurological symptoms, protein should be prohibited.
