The purpose of diet therapy is to improve appetite and digestive function through diet therapy; to correct the cause of the disease and control the development of the disease; to supply rich nutrients, enhance the body’s resistance, promote liver cell repair and regeneration, and liver function recovery. The diet should be high in calories, high in protein, high in vitamins and moderate in fat. 1, caloric energy: the total daily supply of caloric energy is 10.46 ~ 11.72MJ (2500 ~ 2800kcal). 2.Protein: supply 1.5~2g/kg/day according to body weight, or 100~120g/d; pay attention to supply a certain amount of high biomass protein; high protein diet is to promote damaged liver cells repair and regeneration. Fibrous tissue after hepatic sclerosis affects blood circulation, portal hypertension occurs, and water and electrolytes in intestinal microvessels diffuse into the abdominal cavity, causing ascites; plasma protein content decreases, which lowers plasma colloid osmotic pressure and further aggravates ascites formation. High-protein diet can correct hypoproteinemia, which is conducive to ascites and edema subsidence. But when there is liver failure or liver coma tendency, to limit the protein supply. 3, fat: supply 40-50g of fat per day, fat should not be too much, because the synthesis and secretion of bile is reduced in liver disease, the digestion and absorption of fat is reduced; too much fat, more than the metabolic capacity of the liver, it is deposited in the liver, affecting the synthesis of liver glycogen, so that liver function is further impaired. But fat should not be too little, too little can affect the taste of food cooking, so that the patient’s appetite decreased. Patients with biliary cirrhosis should be given a low-fat, low-cholesterol diet. 4, carbohydrates: adequate liver glycogen storage can prevent toxin damage to liver cells; carbohydrate supply should be 350-450g/d is appropriate. 5, vitamin: liver directly involved in the process of vitamin metabolism, vitamin C to promote the formation of liver glycogen; increase the concentration of vitamin C in the body, can protect the resistance of liver cells and promote the regeneration of liver cells. The concentration of vitamin C in ascites is equal to the content in blood, so vitamin C should be supplemented in large quantities when there is ascites. Vitamin K is related to the synthesis of prothrombin, and should be given to patients with prolonged coagulation time and bleeding in a timely manner. 6, sodium and water: patients with edema and mild ascites should be on a low-salt diet, with a salt intake of no more than 2g per day; in the case of severe edema, a salt-free diet is recommended, with sodium limited to about 0.5g per day and sodium-containing foods prohibited, such as seafood, ham, puffed eggs, meat loaf, pickles, etc.; water intake should be limited to less than 1000ml per day. 7, trace elements: patients with hepatic sclerosis have lower serum zinc levels, increased urinary zinc excretion, and lower zinc content in the liver, so attention should be paid to zinc supplementation. It is advisable to use more lean pork, beef, mutton, eggs, fish and other foods with high zinc content. Patients with hepatic sclerosis often have magnesium ion deficiency and should be supplemented with foods containing more magnesium, such as green leafy vegetables, peas, dairy products and cereals. Shanghai Longhua Hospital splenic and gastrointestinal disease department Dai Yancheng 8, cirrhosis portal hypertension patients, should avoid eating rough and hard, irritating food. Should chew slowly, eat food containing less coarse fiber, should not eat leeks, celery, dried bamboo shoots, etc. and dried fruits, keep the stool usually, avoid increasing abdominal pressure action.
