The presence of Helicobacter in the body is usually due to infection by germs. When eating together, it is easy to spread through the oral route. If one of the people eating together has Helicobacter, it may cause others to be infected, and people who eat out often are prone to this type of infection. Some patients like to eat uncooked food, but there are many bacteria in uncooked food, which increases the chance of infection with Helicobacter. Improper diet and overexertion can also cause spleen deficiency, and Helicobacter infection is closely related to spleen deficiency, and patients with spleen deficiency are more likely to be infected with such bacteria. Due to the reduced defense function of the gastrointestinal mucosa, the bacteria can easily enter the body and affect the intestinal health.
