The full name of Hp in Chinese is Helicobacter pylori, and some children can recover from H. pylori infection on their own, while adults generally do not recover on their own, but can have no obvious clinical symptoms. H. pylori is a gram-negative microaerobic bacterium that mainly exists in the stomach and duodenum and other digestive tracts, and can cause chronic inflammation of the gastric mucosa, ulcers, and even cancer, resulting in stomach pain, acid reflux, heartburn, and other symptoms. Due to the characteristics of Helicobacter pylori, gastric acid and other digestive juices can not eliminate it, and the symptoms of Helicobacter pylori infection can be exacerbated by irregular diet, living habits, and stimulation of digestive juices, and medical intervention is needed to cure it. After the test suggests that H. pylori is positive, it is recommended that the patient complete the relevant examination, clarify the condition and then give standardized treatment to avoid adverse effects.
