H. pylori infection is mainly associated with living habits, family aggregation, age, and medical infection.
1. Lifestyle habits, the pathway of H. pylori infection is not clear, and the possible modes of transmission are oral droplet or fecal-oral route. Therefore, bad living habits, such as drinking raw water, consuming undercooked food, and frequently consuming pickled food, may cause H. pylori infection.
2. Family aggregation. Relevant data show that children of H. pylori infected parents have a higher risk of infection than those of uninfected families, but the genetic susceptibility of H. pylori has not been confirmed.
3. Age, H. pylori infection often has a certain correlation with age, in which the infection rate of elderly people over 70 years old is as high as 80%, and children are also the high-risk group of H. pylori infection.
4. Medical infection, if in the medical treatment, the stomach related examination instruments are not sufficiently sterilized, it may cause medical infection and transmission.
Helicobacter pylori infection colonizes the surface of gastric epithelial cells and is difficult to remove itself, producing a variety of enzymes and cytotoxins that have a destructive effect on the gastric mucosa, manifesting itself in a variety of gastric symptoms, so it is important to go to a regular hospital in a timely manner to seek medical treatment after the identification of Helicobacter pylori infection.
