The purpose of the 10-year follow-up of atrophic gastritis with enterocolitis is mainly to determine the survival of the patients, whether they are cancerous and their treatment, and to conduct evidence-based research. Atrophic gastritis with enterocolitis is a precancerous lesion with the possibility of malignant transformation into gastric cancer. Once it develops into gastric cancer, it will have an impact on the patient’s quality and duration of survival, and the follow-up will help to know whether it is malignant or not, and whether it affects the patient’s life or not. There is no definitive treatment for atrophic gastritis that can reverse this change, and the main focus is on improving symptoms. Follow-up visits are used to find out if treatment and tests are appropriate and how effective they are, and to test current treatment options through evidence-based medicine. If you have atrophic gastritis with enterocolitis, you should follow your doctor’s instructions and cooperate with tests and treatment. It is important to actively improve the quality of life to avoid its development into gastric cancer.
