Gastric erosion refers to limited damage and erosion of gastric mucosal epithelium, which may lead to cancer if no effective intervention is made for a long time. Gastric erosion is mostly seen in gastritis, gastric ulcer and other digestive diseases, which can lead to nausea, acid reflux, belching, abdominal pain, vomiting and other uncomfortable symptoms. Especially people who usually have irregular diet, alcoholism, smoking or infected with Helicobacter pylori are prone to this disease. Without timely intervention, gastric erosion is increasing and may become cancerous. In particular, gastric celiac disease caused by H. pylori infection is one of the most important triggers of gastric cancer. Currently, H. pylori has been classified as a class I carcinogen by the WHO. Once symptoms of celiac disease appear, you should seek medical examination as soon as possible to confirm the diagnosis of the condition.
