Atrophic gastritis is generally not contagious, except for chronic atrophic gastritis that is clearly caused by Helicobacter pylori infection, and it is possible to transmit H. pylori through utensils or food when eating together with the patient, but the chance of transmission is quite low, so you do not need to worry. It is important to emphasize that if the patient has an electrogastroscopy plus pathological examination, it is clear that there is atrophy of the gastric mucosa, i.e. atrophic gastritis. If the infection is caused by Helicobacter pylori, it is necessary to eradicate it. The principle of the entire treatment requires careful use of acid-suppressing drugs, such as omeprazole, lansoprazole, and eprazole-type drugs. At the same time, it is necessary to follow the doctor’s instructions for close review and follow-up until atrophic gastritis is cured mainly to avoid the possibility of further aggravation of gastric mucosal atrophy developing into precancerous lesions and even into gastric cancer.
