Moderate intestinalization is short for moderate epithelial hyperplasia of the gastric mucosa intestines. With standardized and reasonable treatment, it is not life-threatening. Moderate intestinalization refers to gastric mucosal lesions, which can be diagnosed by taking mucosal biopsy and doing pathology under gastroscopy. It is true that there is a possibility of cancer, but it is not absolute. Generally, it is a slow process to develop to moderate intestinalization and then progress to gastric cancer. The main cause of gastric cancer is chronic inflammation of gastric mucosa, which may be related to Helicobacter pylori infection and irregular diet, etc. If moderate gastric cancer is detected, the cause of gastric cancer should be actively identified, and treatment should be carried out as soon as possible under the guidance of doctor, and the dietary and work habits should be adjusted, then moderate gastric cancer has a great possibility of no further progression, and will not be life-threatening. However, gastroscopy should be done at least once a year. Even if the disease progresses to gastric cancer, if it is detected early and can be treated by surgery, the patient can live for a long time. If there are symptoms of moderate intestinalization, it is recommended to go to the hospital as soon as possible and take appropriate measures under the doctor’s guidance.
