There are no epidemiologic surveys that clearly indicate the probability of gastroscopic detection of non-atrophic gastritis. Non-atrophic gastritis is one of the most common diseases in gastroenterology, which is related to Helicobacter pylori infection and abnormal gastric acid secretion, etc. The environment, dietary factors, mental stress, and bad hobbies are all causative factors, and it usually manifests itself as epigastric discomfort, nausea, vomiting, loss of appetite, and malaise, etc. Anemia or even carcinoma may occur in long-term non-intervention. Gastroscopy is the gold standard for non-atrophic gastritis, and some studies have shown that patients with chronic gastritis, including atrophic gastritis, account for about 80% to 90% of patients who undergo gastroscopy. It is clear from this that the probability of gastroscopic detection of non-atrophic gastritis is insufficient to reach 90%, although there are no epidemiologic surveys that clearly indicate the probability of gastroscopic detection of non-atrophic gastritis. Patients with non-atrophic gastritis should be treated as early as possible under the guidance of a medical professional.
