The symptoms of chronic atrophic gastritis with intestinalization are mainly the following: Acid reflux: In clinical practice, we find that some patients with hyperacidic atrophic gastritis are often accompanied by heartburn and acid reflux symptoms. Indigestion: Atrophic gastritis is characterized by a lack of stomach acid and disorders of the spleen and stomach, so that the food ingested by the patient is not completely digested, which leads to symptoms of bloating, belching and burping due to diet. Stomach pain: Due to the vascular permeability of the gastric mucosa and the thinning of the mucosa, the mucosa is worn down by the large amount of food ingested in the diet, and patients with high acidity atrophic gastritis are extremely susceptible to injury to the nerve endings, resulting in pain in the stomach. Anemia: malabsorption of vitamin B12 and megaloblastic anemia. Precancerous symptoms: intestinal metaplasia, atypical hyperplasia and heterogeneous hyperplasia are regarded as precancerous states of the stomach. It rises with age and the ratio of intestinalization increases along with the enlargement of the atrophic zone. The distribution of intestinal hyperplasia and atrophic gastritis sites is also basically the same, with the highest rate of appearance in the gastric sinus, followed by the body sinus migration site. Since atrophic gastritis and intestinal epithelial hyperplasia are closely related to the occurrence of gastric cancer, such patients should be given high priority in clinical practice, with long-term follow-up and regular review to prevent carcinogenesis. Therefore, there are many symptoms of chronic atrophic gastritis with intestinal metaplasia, so when similar symptoms appear, you should seek medical attention as soon as possible to avoid delaying the disease.
