Eat a small amount of warm water (about 20ml) first. If there is no discomfort, then eat rice soup. Please follow the principle of eating less and eating more meals, and the amount of each meal should not be too much. Please have a cup of rice soup in our canteen 3-4 times. On the first day after operation, it is only suitable for eating warm water, porridge soup or rice soup. Do not eat fish soup, milk, etc. It is easy to cause diarrhea, and intestinal bleeding can occur in severe cases. Generally, you can eat semi-liquid with low residue on the second day after operation, but you should eat under the guidance of a doctor, such as porridge and rotten noodles. And eat less and eat more. Avoid eating too much. If you feel unwell after eating, you should report it to the doctor in time so as to relieve the discomfort as soon as possible. Within a week, semi-liquid digestible food, such as porridge, rotten noodles, etc. After a week, it will gradually transition to a normal diet. Eat more raw pear juice, lotus root juice, water chestnut juice, reed root juice, celery juice, carrot, white radish (cooked food), bitter gourd, eggplant, cucumber, spinach, day lily, Chinese cabbage, egg yolk, apple, fig, banana, black sesame, walnut kernel and other foods with the functions of clearing heat from the intestines, nourishing mucous membranes, relaxing bowels and stopping bleeding.

The quality of the diet should start from soft and gradually adapt to the body before adding other diets. Be careful not to eat too much fat. Foods such as sugar, fat, protein, minerals and vitamins should be reasonably matched. There should be grains, lean meat, fish, eggs, milk, various vegetables and bean products every day, and the amount of each should not be too much. Only in this way can we supplement all kinds of nutrients needed in the body. Pay attention to eat more vegetables rich in dietary fiber, such as celery, leek, cabbage, radish and other green leafy vegetables. Vegetables rich in dietary fiber can stimulate intestinal peristalsis, increase defecation times, and take away carcinogenic and toxic substances in feces. If colonic polyps protrude into the intestinal cavity and the intestinal cavity narrows, it is necessary to control the intake of dietary fiber, because excessive intake of dietary fiber will cause intestinal obstruction. At this time, digestible, soft and semi-liquid foods should be given, such as millet porridge, lotus root powder thick soup, rice soup, porridge, corn porridge, egg soup and tofu. These foods can reduce the irritation to the intestine, pass through the intestinal cavity smoothly and prevent intestinal obstruction. What should I eat after colon polyp surgery? 1, suitable for pasta. Pasta is easy to digest and fits the intestines very well. Moreover, patients who eat vegetarian noodles, steamed bread and other foods are conducive to the recovery of the intestines and are not easy to produce all the toxins of other foods. So patients with anorectal diseases are more suitable for eating pasta. 2, appropriate porridge. There are many ways to make porridge. Patients with intestinal polyps are weak after operation and need some supplements. Therefore, some vegetables and fruits, such as red beans, radishes, apples, etc., can be properly added to the porridge, which will be dull and nutritious and conducive to the patient's physical recovery. 3. Suitable for alkaline food. Patients with polyps should eat more alkaline food to improve their acidic constitution. For example, Chinese cabbage, kelp buds, kelp and onions in vegetables are weakly alkaline. What should be avoided after colon polyp surgery? 1, avoid greasy food. For example, fried smoked food and greasy food will stay in the intestines for a long time, causing digestive problems and easily causing intestinal burden, so don't eat them. 2, avoid spicy food. Don't touch irritating food such as liquor, pepper and vinegar in the recovery period after operation, so as not to cause irritation and congestion to the postoperative wound. 3, avoid acidic food. Cheese, persimmon, meat, fish, egg yolk, bread, wheat, cream, etc. They are all acidic foods, and patients with intestinal polyps must avoid these foods after surgery to avoid slow recovery. Alcohol and tobacco are extremely acidic substances, and people who smoke and drink for a long time are prone to acidic constitution. 4, do not eat contaminated food, such as contaminated water, crops, poultry and fish eggs, moldy food, etc. Eat some green organic food to prevent diseases from entering the mouth. At the same time, the recurrence of intestinal polyps is related to living habits. If you still eat fatty food after resection, you can also induce intestinal polyps. It is suggested that patients with intestinal polyps should have a light diet, eat less foods that are difficult to digest and stimulate, such as frying, frying and spirits, and eat more fresh fruits and vegetables. Generally speaking, soft and digestible food is the main food. Remember not to drink or smoke, and insist on proper exercise.
