Only after six months may ride a bicycle. 2, either primary or secondary surgery, there will be a legacy of abdominal adhesions and intestinal adhesions. According to our experience, there is no ideal way to prevent adhesions. The general principle is to avoid overexertion, moderate exercise, and better nutrition. The gastrointestinal tract is an emotionally susceptible organ, so try to lead a peaceful life and avoid great joy and grief. 3.After discharge from the hospital, a three-step approach can be taken to resume the diet. The first month is based on flowing juice, such as fish soup, light chicken soup. Eight words of health maxim: think more, think less, move diligently and eat lightly. Soup, soy milk, milk and various fruit juices are the mainstay. The second half of the month can also eat a slightly thinner thin gruel. The second month is mainly semi-juice, such as slightly thicker rice porridge, steamed eggs, noodles, fluffy cakes, etc. In the third month, semi-liquid juice is changed to normal diet. During the whole recovery period, in order to ensure sufficient energy and protein supply, enteral nutrition solution should be fed intranasally at the same time. In the first period, peptide-based nutritional solutions such as Bupropion and Bupropion are the mainstay, and in the later period, whole protein-based nutritional solutions such as Ensure and Energize are the mainstay. The main advantage of nasal nutrition solution is to ensure that the body can have sufficient nutrients in reasonable proportion during the postoperative recovery process. Fish soup and chicken soup can only meet the psychological needs, but not the nutritional needs. 4.Eating ordinary diet also still focuses on high nutrition and high protein easy to digest diet. Food must be fully chewed and adequately crushed food to reduce the burden on the stomach. Preferably supplemented with one-quarter or one-half hear of Ensure powder daily. To supplement the diet with insufficient nutrients and insufficient energy and protein. Protein powder is only a simple protein, can not supplement the body needs a variety of nutrients. 5, it is strictly forbidden to eat persimmons, persimmon cake, hawthorn (including sugar cakes), dates. These foods contain tannic acid, which will clump with the protein in the food, wear the stomach wall and lead to gastric ulcers. Since all patients have varying degrees of adhesions after surgery, they cannot eat whole foods or foods that tend to clump together in the intestines. This can block the intestinal canal and cause intestinal obstruction. There are few patients who are re-operated as a result. Avoid swallowing food in whole pieces. Foods that are easily swallowed in chunks, such as yams and rice cakes, should be eaten sparingly or not at all. The principle is the same, they can cause intestinal obstruction in patients after abdominal surgery. 6, weekly monitoring of weight. If your weight drops, you should eat more food. If the weight keeps dropping, below 10% of the current weight, or if the weight loss is more than 5 kg, you should review it promptly. Find out the reason for the weight loss.
