Gastric atrophic gastritis with severe intestinalization has a higher chance of becoming cancerous, which needs to be judged according to the severity of gastritis as well as individual’s physique. Gastric atrophic gastritis does not exclude the possibility of cancer, if it is not treated timely and correctly, the condition will progress gradually and eventually develop into cancer. The severity of each person is different, and the effect will be different after the use of medication, such as drugs to inhibit gastric acid and drugs to protect the gastric mucosa, and the specific medication needs to consult the doctor. In addition, it is also affected by autoimmunity. If one’s own resistance and immunity are stronger and one’s physique is better, it is conducive to the recovery of the disease. It is recommended that during the treatment period, patients should have regular body checkups and pay attention to the development of gastritis. There is no need to be overly nervous, as it often takes years or even decades to develop into stomach cancer.
