As an important digestive organ, the liver plays an irreplaceable role in the whole organism. As the most thorough and effective treatment for liver tumors, liver resection often requires removal of some liver tissues, which inevitably affects the physiological functions of the liver. Generally, patients need to fast for 2-3 days after hepatectomy, and then gradually transition to liquid food. So what do patients need to pay attention to after discharge from the hospital diet? 1.Less food and more meals Patients should adhere to the principle of less food and more meals after hepatectomy. Bile secretion is an important physiological function of liver, which can promote the digestion of food and convert glucose and fat into daily energy. Patients after liver resection, the volume of the liver is significantly reduced in a short period of time compared with before, and it is often difficult to produce enough bile, so patients after liver surgery can have a small number of meals in a short period of time, 4 meals a day or 6 meals a day, which will facilitate the digestion of food. 2.Balanced nutrition Balanced nutrition is very important for patients after hepatectomy. Because the nutritional value in rice and flour is often not high, the intake of sugar-based nutrition is best to choose fruits and vegetables. Protein should be mainly lean protein, such as fish, chicken, eggs, beans, nuts and so on. In addition, because it is difficult for the liver to produce enough bile to help digestion of fat after surgery, it is best for patients to avoid fried or fatty foods. Patients should not eat spicy, coarse, hard and stimulating foods, because these foods will stimulate the digestive tract and induce nausea and vomiting, which are not conducive to recovery. Patients should also pay attention to abstain from alcohol, because ethanol is the main component of alcohol, and the liver is the main place of its metabolism, too much alcohol can cause degeneration and necrosis of liver cells, which is harmful to postoperative recovery. In addition, excessive nutritional products should be avoided after surgery, as these supplements may increase the load on the liver, which is detrimental to the recovery of liver function. In conclusion, the postoperative diet of liver cancer should be light, small amount of meals, varied food and balanced nutrition, avoiding tobacco, alcohol, stimulating food and fried food. It is believed that a healthy and balanced diet will help patients recover as soon as possible and get back to their normal life and work.
