It is often said that disease enters through the mouth, because the first thing that you eat is the stomach. The stomach has the function of storing, digesting and transporting food. Therefore, eating disorders are an important factor in causing gastric diseases. Chronic gastritis is a very common gastrointestinal disease, with non-specific inflammation of the gastric mucosa as the main pathological change. The common clinical symptoms are: epigastric distention, pain, frequent warmth, acidity, loss of appetite, emaciation and diarrhea. Chronic atrophic gastritis patients, especially those with moderate to severe atrophic gastritis with intestinal glandular hyperplasia or atypical hyperplasia, have a higher incidence of gastric cancer than the general population, and it is reported that about 5-10% of patients can eventually be transformed into gastric cancer, but there is no necessary connection between atrophic gastritis and gastric cancer. However, there is no necessary link between atrophic gastritis and gastric cancer. Moreover, the lesions of the gastric mucosa can be reversed if treated properly. Therefore, it is very important for patients with chronic atrophic gastritis to be reviewed regularly. The treatment of chronic atrophic gastritis is mainly symptomatic. Also avoid drugs that damage the gastric mucosa, such as aspirin, anti-inflammatory pain, erythromycin, cortisone, etc. In particular, some drugs for cold may also stimulate the gastric mucosa. According to personal experience, if the upper abdominal discomfort, belching and acid reflux symptoms worsen after taking that kind of cold medicine, you should try to avoid taking such drugs in the next cold. For patients with positive H. pylori detection, antibiotics should be taken, such as amoxicillin capsules, which can directly kill the bacteria, Lizudra should also be used, his main component is colloidal bismuth subcitrate, the drug can and inflammatory exudate and mucin to form a complex, wrapping bacteria so that they lose the ability to adhere to the epithelial cells, bismuth ions into the bacteria to kill them. At the same time, gastric mucosal protective agents can be used. Protect and enhance the gastric mucosal defense function, commonly used gastric mucosal protective agents are colloidal sub raffinate button (such as Denox or Delo), magnesium aluminum carbonate, Metzolim-S, prostaglandin, etc.. In addition, improve gastric motility, is also the key to treatment, such as morpholine, mosapride can increase the tension of the lower esophageal sphincter, enhance gastric peristalsis, promote gastric emptying, coordinate gastric and duodenal movements, prevent bile reflux, regulate and restore gastrointestinal motility, and have good effect on eliminating the feeling of fullness, bloating, postprandial discomfort, epigastric burning sensation, nausea, etc., with little side effects. In addition, because of the important role of dietary factors in the development of chronic gastritis, good eating habits are the key to preventing and treating gastritis, which is different from other diseases. In general, the following points should be done when eating: First, chew slowly to reduce the stimulation of food to the gastric mucosa. The actual fact is that you can find a lot of people who are not able to get a good deal on a lot of things. Third, pay attention to dietary hygiene, to eliminate the infringement of external microorganisms on the gastric mucosa. Fourth, try to eat more fine and easy to digest, rich in vitamin food. Five, light and less fatty, sweet, thick, greasy, spicy food, less alcohol and strong tea. Six, drink two servings of milk every day. Seven, do not eat pickled products (such as pickled vegetables, dried roti, salted fish, salted meat, salted duck eggs, etc.) and smoked food. Eight, do not eat leftovers, that is, do that eat, because the leftovers in the nitrite content is very high, carcinogenic effect.
