With the improvement of living standard and quality of life, people are more and more concerned about the health of their bodies. Everyone wants to have a good appetite, and a good appetite is also a key factor in a high quality of life. The concern for the stomach is elevated to a higher level. Chronic gastritis is a common disease that refers to various chronic inflammatory lesions of the gastric mucosa caused by different etiologies, with the main clinical manifestations being epigastric pain, fullness, belching, acid reflux, heartburn, etc. Its incidence ranks first among gastric diseases. Once you suffer from chronic gastritis is difficult to cure, a little carelessness in daily life will have naughty ghosts out to torment your stomach, food can not enjoy at will, but also suffer from pain. Chronic gastritis is one of the most common diseases in gastroenterology clinics, especially in China, where food hygiene needs to be improved, and a wide variety of sweet, sour, bitter, spicy and salty foods continue to challenge the limits of people’s gastric mucosa. There are probably not many Chinese adults with completely normal gastric mucosa phase, and most of them have experienced gastritis. Chronic gastritis is very common, accounting for about 80%-90% of patients undergoing gastroscopy, more men than women, and the incidence increases with age. Although some of its causes are closely related to H. pylori infection, there are other causative factors that are still not fully understood. Among the various causes of chronic inflammatory lesions of the gastric mucosa, physical, chemical and biological factors can cause the disease by acting repeatedly on susceptible humans over a long period of time, and chronic lesions can be formed by the persistence or recurrence of the cause. We also found in our clinical work that the incidence of chronic gastritis is significantly higher than the average population of people engaged in competitive and mentally stressful occupations, which shows that mental factors cannot be ignored. Some patients find that gastroscopy in different hospitals, the same chronic gastritis, but the diagnosis is often inconsistent, some for superficial gastritis, some for erosive gastritis, while another hospital may be diagnosed as reflux gastritis. After going around in several hospitals, patients are often confused about what kind of gastritis they have. To clarify this issue, it is important to start with the classification of gastritis. Because the clinical manifestations of chronic gastritis, gastroscopic findings and gastric mucosal biopsies are sometimes inconsistent, there is no unified and reasonable classification standard for chronic gastritis to date. There are classifications by etiology, such as drug gastritis, alcoholic gastritis, and reflux gastritis; by lesion morphology, such as erosive gastritis and warty gastritis; by lesion site, such as gastritis of the sinus and gastric body; and by pathology, such as superficial gastritis and atrophic gastritis. Currently, chronic gastritis is usually referred to as chronic superficial gastritis and chronic atrophic gastritis, and both can often coexist. In chronic non-atrophic gastritis (also known as chronic superficial gastritis), the depth of the inflammatory lesion does not reach deep into the mucosal muscle layer, and therefore does not develop into gastric cancer. However, chronic atrophic gastritis is related to gastric cancer for three reasons: 1. Most gastroscopic biopsies of atrophic gastritis are often accompanied by “intestinal epithelial hyperplasia” and “atypical hyperplasia”, two types of gastric mucosal lesions, which may develop into Gastric cancer. 2.Epidemiological survey found that the incidence of atrophic gastritis is also high in the population with high incidence of gastric cancer. 3.Pathological examination of gastric cancer reveals that atrophic lesions are common in the mucosa surrounding gastric cancer. The hypothesis that gastritis evolves into gastric cancer is: superficial gastritis – atrophic gastritis – intestinal epithelial hyperplasia and atypical hyperplasia – gastric cancer. The chilling statement that “atrophic gastritis is just one step away from gastric cancer” has been made. However, the latest domestic and international research shows that there is a long process from atrophic gastritis to gastric cancer, and there is no conclusion that atrophic gastritis is bound to develop into gastric cancer. The occurrence of gastric cancer is related to the length of history of atrophic gastritis and the severity of the disease. With the current medical technology, the cancer of atrophic gastritis can be controlled through effective medication and minimally invasive treatment, so patients with chronic atrophic gastritis do not need to carry too heavy a burden of thought. Most superficial gastritis can be reversed, and a small percentage can be converted to atrophic. Atrophic gastritis gets progressively worse with age, but mild cases can be reversed. The actual fact is that you can get a good deal of time and effort to get a good deal of time and effort. The treatment of chronic gastritis should eliminate the causes of the disease: remove various factors that may cause the disease, such as avoiding diets and drugs that have a strong stimulus to the gastric mucosa, quit smoking and avoid alcohol. Pay attention to dietary hygiene, prevent overeating, strengthen exercise to improve physical fitness. Drug treatment includes acid suppressants, gastric mucosal protectors, anti-H. pylori treatment and traditional Chinese medicine.
