Clinical studies have shown that pyloric duct ulcers have a tendency to recur, and that delayed gastric emptying and bile reflux, the action of gastrointestinal peptides, genetic factors, drug factors, environmental factors and mental factors are all related to the occurrence of pyloric duct ulcers. Dietary principles: 1. Reasonable collocation, should not be partial diet: Since many patients are sexually stressed and have the characteristic of being picky about their diet, it is necessary to make a reasonable meal collocation according to the patient’s taste, but also to instruct patients not to be partial to their preferred diet. At the same time, the main and side dishes should be matched, not only to enhance appetite, and can improve the physiological value of protein, which is conducive to the repair of ulcers. 2, develop regular eating habits: the amount and regularity of eating in peptic ulcer patients is directly related to the occurrence of pain, irregular eating destroys the rhythm of gastric juice secretion. When too hungry, there is no food in the stomach to neutralize gastric acid, so that the relative increase in gastric acid and pepsin, thus stimulating the ulcer, causing pain and difficult to heal; when too full, it will make the stomach wall overexpand, which is very easy to damage the self-protection mechanism of the stomach, thus aggravating the ulcer. During the attack period, a small number of meals, 5 to 7 meals per day, the amount of each meal should not be more, easy to choose soft and easy to digest food. After the disease is stabilized, 3 meals per day can be given to normal general food to ensure the balance of various nutrients. 3, pay attention to the main food and side food, dry food and thin food collocation: main and side food coordination can not only enhance appetite, but also improve the physiological value of protein, conducive to the repair of ulcers, the main food to achieve a reasonable collocation of coarse and fine grains, that is, the main fine grains, coarse and fine grains. The main side dishes to do with meat and vegetarian dishes and the variety of varieties. 4, food should be light: the production of food should be used less smoke and oil explosion, especially fish and meat. Salt intake should be controlled and should not exceed 8 grams per day, and vegetable oil should be used in the cooking process as much as possible. 5.Food should be fresh: patients’ diet should be fresh. Improperly stored or too long food may produce carcinogenic substances. 6.Do not eat too cold and too hot food: Because the gastric mucosa is delicate and can only withstand a temperature of 50-60°, too cold or too hot food can stimulate the mucosa of the digestive tract, which is not conducive to ulcer repair. 7, to develop a good habit of chewing and swallowing: eat not too quickly, develop a good habit of chewing and swallowing, chewing and swallowing can increase the secretion of saliva, while reducing the secretion of gastric acid and bile, which is conducive to the protection of the stomach; if swallowing, food rough, it will increase the burden on the stomach, resulting in damage to the gastric mucosa, aggravating the ulcer. 8, the attack period to a small number of meals: regular ration, avoid overeating, the tendency to attack or good season, should eat more neutral and alkaline food, less vinegar and spicy food. 9. Be sure to eat breakfast on time every day: you cannot skip breakfast or postpone it for more than one hour for any reason. 10, develop good cooking and eating habits: the food eaten should be less salt, can use steam, boil, boil, soft boil, braise, stew and other cooking methods, should not use grease, frying, frying, vinegar, cold and other methods. When eating should chew and swallow slowly to facilitate digestion. 11, forbidden to take a variety of ulcer-inducing drugs: patients forbidden to take non-steroidal anti-inflammatory drugs, aspirin, corticosteroids steroids such as reserpine. Because these drugs can directly damage the gastric mucosa, stimulate increased secretion of gastric acid, inducing or aggravating ulcer formation.
