Kissing does not transmit gastric disease, but it can transmit the virus that causes gastric disease.1. Since Helicobacter pylori is a virus that spreads by mouth-to-mouth transmission, sharing utensils over meals and kissing can lead to the spread of the virus. This type of virus is transmitted and parasitized in the human mouth and stomach, causing lesions in the gastric mucosa. It has been shown that Helicobacter pylori is the main factor in the development of atrophic gastritis, intestinal epithelial hyperplasia, atypical hyperplasia, and finally gastric cancer.2. If the gastric mucosal damage caused by dietary factors stress factors, mainly manifested as local inflammatory factors, which is a kind of immune response of the human body. Gastritis or gastric ulcer caused by non-Helicobacter pylori infection will not spread to others through kissing. When someone in the family is infected with H. pylori, meals should be shared to avoid transmission to immunocompromised members of the family.
