Chronic atrophic gastritis is a very common chronic gastric disease that often presents with discomfort such as epigastric pain, bloating, belching, heartburn, acidity and loss of appetite, and in severe cases, anemia and weight loss. Therefore, chronic atrophic gastritis combined with intestinal epithelial hyperplasia or atypical hyperplasia is usually given sufficient clinical attention by doctors and patients. The cause of chronic atrophic gastritis is not very clear, but it is generally believed that a variety of causes are related to the onset of the disease. In the elderly, long-term gastric diseases are not well treated, resulting in the degeneration of gastric secretion and motor function, while adolescents may be related to high study pressure, cold and spicy food, and study or strenuous exercise without rest after meals. In conclusion, the long-term stimulation of the gastric mucosa by various physical, chemical and biological factors may be the cause of atrophy of the gastric mucosa, among which the most important is the food that we are exposed to every day. How to pay attention to the diet taboos, is to avoid the occurrence of chronic atrophic gastritis is an important aspect, specifically, is ” five appropriate five taboos ” diet taboos: 1, avoid eating spicy cold temperature is too high and too low, should be calm and less stimulating food: especially in the wind and rain, the climate is very dry northern areas, spicy food can consume more water in the body. Not only lead to dry mouth, but also stimulate the mucous membrane of the stomach and intestines, making the mucous membrane congestion and edema; some people like to eat especially hot food, even just cooked hot porridge dare to drink, not hot, too high temperature burns the mucous membrane of the esophagus and stomach, causing congestion and edema inflammation of these parts of the mucous membrane tissue; cold food can lead to gastric capillary constriction, affecting the blood supply of the gastric mucosa, cold food also makes the stomach smooth muscle contraction, aggravating the ischemia of the gastric mucosa. Especially serious is that too cold and too hot food together, the stimulation of the gastric mucosa is more obvious. Long-term hot and cold food stimulation will lead to chronic inflammation of the gastric mucosa. 2, avoid eating pickled smoked, fresh food: starchy food after high temperature frying, can produce carcinogenic acrylamide, food in the process of pickling or smoking, easy to produce a large number of nitrosamines, these are carcinogenic substances; high salt content in the pickled food can damage the gastric mucosa, so that the gastrointestinal mucosa inflammation; in the pickled food to add more preservatives and flavors, colors, etc., all have a bad effect on the human body . 3, avoid tobacco, strong tea and coffee, it is appropriate to ordinary white water: alcohol is one of the few substances that can be absorbed directly by the gastric mucosa, through the observation of gastroscopy, 1-2 days before the examination of alcohol, gastroscopy can be seen in the gastric fundic mucosa a large number of spots and patches of congestion, such congestion spots in the following days can subside, if a large number of long-term alcohol consumption, repeatedly stimulate the gastric mucosa will If a large amount of alcohol is consumed over a long period of time, repeated irritation of the mucosa of the stomach can cause chronic inflammation of the stomach. Nicotine in tobacco can be absorbed in the body to stimulate capillaries, so that the capillary wall thickening, poor blood flow, so as to affect the supply of nutrients to the gastric mucosa, over time there will be a lack of blood oxygen supply and lead to mucosal atrophy. Tea and coffee contain caffeine that can stimulate the secretion of gastric juice, long-term consumption of large quantities can cause a large number of gastric mucosa secretion, stimulating the gastric mucosa caused by inflammation of the gastric mucosa. Therefore, light tea or light coffee, or ordinary plain water is more suitable for the body’s need for water. 4, avoid eating unclean and corrupt, preferably clean and less contaminated food: corrupt and unfresh food can bring a large number of bacteria into the stomach, resulting in inflammation of the gastric mucosa. Modern planting industry in order to improve production, pest control, before and after the planting of vegetables and fruits, as well as after the picking of fresh, promote maturity, need to apply a lot of a variety of chemical fertilizers, pesticides and agricultural chemicals, these chemicals are easy to attach to the leaves and epidermis of vegetables and fruits, and even contained in vegetables and fruits, if not cleaned before consumption, it can enter the body when eating, long-term exposure to these Chemical substances, will cause bad effects on the human body. Therefore, in the consumption of fresh melon fruit pear peach and green vegetables must be fully soaked before cleaning, can be peeled as much as possible, to reduce the intake of chemical substances. 5, avoid hunger and satiety disorders, overeating, it is appropriate to three meals regularly quantitative: some people do not eat breakfast or for some reason can not eat regularly, hunger and satiety disorders, these are not good eating habits, do not eat breakfast, the stomach for a long time in a state of emptiness, making the stomach acidity increased, and, for a long time without food, the concentrated bile in the gallbladder does not have the opportunity to excrete, in a highly concentrated state easy to make the gallbladder inflammation, and even mutual The gallbladder does not function well, which makes it easy for bile to flow back into the stomach, and over time, this is one of the reasons for the formation of atrophic gastritis. The actual fact is that you can find a lot of people who have been in the business for a long time, and they’ve been in the business for a long time, and there’s no food to neutralize the gastric acid, and the gastric acid is too high to stimulate the mucous membrane of the stomach so that the gastric mucous membrane becomes inflamed. On the one hand, a short period of time to make the empty stomach cavity at once full, over time, will cause problems with the tension of the stomach, can not be well retracted, on the other hand, will also increase the burden on the stomach, making the stomach symptoms of indigestion. And three meals at regular intervals, each meal interval of about 4-5 hours is in line with the gastric digestive physiological cycle, because under normal circumstances, the emptying of the stomach according to the different diets and water content, about 3-4 hours, fatty food emptying time is the longest, starchy food is the shortest, protein food between the fat and starch. Eat some time after the stomach has completely emptied, so that the stomach can have a period of rest and restore the physiological function of the stomach. The stomach is very fragile, and once it is out of order, it is not easy to recover, so it is important to protect the gastric mucosa in the daily diet, to protect the gastric function, to minimize the stimulation of the gastric mucosa, to reduce the damage to the gastric mucosa including various physical, chemical and biological factors, to take inhibitory measures when the gastric mucosa is first lesioned so that it does not continue to aggravate, and to take active measures in the early stage of atrophic gastritis to prevent further deterioration into In the early stage of atrophic gastritis, active treatment measures are taken to prevent further deterioration to severe atrophic gastritis and even gastric cancer.
