Atrophic gastritis, also known as chronic atrophic gastritis, is a type of chronic gastritis that manifests clinically as a granular mucosa with revealed blood vessels, grayish color, and small folds. It is often accompanied by erosion or with bile reflux. It may manifest as discomfort in the upper and middle abdomen, fullness, vague pain, burning pain without rhythm, or indigestion symptoms such as loss of appetite, belching, acidity and nausea. Signs are not obvious, and sometimes there is light pressure pain in the epigastrium. Atrophic gastritis combined with pernicious anemia often has generalized weakness, fatigue, may appear obvious anorexia, weight loss, anemia, while the digestive symptoms can not be obvious. There is no effective treatment, mainly symptomatic treatment, treatment includes the following ways: 1. Patient education: food should be diversified, avoid partial diet, pay attention to supplement a variety of nutrients, do not eat moldy food; eat less smoked, pickled, rich in nitrate and nitrite food, eat more fresh food; avoid too rough, strong, spicy food and a lot of long-term drinking, quit smoking; maintain a good mental state and Adequate sleep. 2, drug therapy: ① improve gastric mucosal inflammation and slow down the progress: for Hp-positive patients, eradication therapy is still the most basic treatment for CAG and intestinal eradication of Hp can reverse or slow down the progress of atrophy. A quadruple therapy consisting of bismuth + PPI + 2 antibacterial drugs is recommended. Supplementation of folic acid and vitamin C can be used as CAG to prevent gastric cancer. ②Symptomatic treatment can be used according to patient’s symptoms with prokinetic drugs: digestive enzyme preparations, etc. For those with epigastric fullness, nausea or vomiting as the main symptoms, prokinetic drugs can be used, while those with bile reflux can apply prokinetic drugs and/or gastric mucosal protective agents with bile acid binding effect; those with obvious indigestion symptoms such as feeding-related bloating and poor appetite can be considered to apply digestive enzyme preparations; for epigastric pain and acid reflux, PPI, H2 receptor blockers or gastric acid neutralizing drugs can be used moderately; those with mental psychological factors, sleep disorders or those with obvious psychiatric factors, those with ineffective conventional treatment and poor efficacy, psycho-psychotherapy can be considered to eliminate or relieve patients’ psychological stress as well as symptomatic treatment of clinical symptoms, which has certain significance in improving prognosis. ③ Specific identification according to the basic theory of Chinese medicine: at the same time, identification according to the symptoms of medical history, endoscopic pathology and laboratory test results, clarify the gastric mucosal lesions and pathophysiological changes of each patient, and individualize the combined treatment of Chinese and Western medicine by combining the disease and evidence. 3, for the cause: the foci of infection in the nasopharynx should be removed, and smoking and alcohol should be avoided. Diet should be soft, easy to digest, avoid too rough, avoid food containing strong seasoning or taking drugs that stimulate the stomach. Geriatric gastric mucosa of varying degrees of atrophy and intestinalization is difficult to reverse, when there is active inflammation to actively treat. 4, on the question of surgery: atrophic gastritis and intestinalization is not an absolute indication for surgery, for those with polyps, heterogeneous hyperplasia or focal depressions or bulges, follow-up should be strengthened. When chronic atrophic gastritis with severe anisotropic hyperplasia or severe intestinal hyperplasia, especially large intestinal hyperplasia, endoscopic ESD surgery may be considered. These are the symptoms and treatment of atrophic gastritis. When similar symptoms appear, you should go to the hospital as soon as possible to find out the specific causes and treat them under the guidance of a clinician, and do not use drugs blindly on your own.
