Positive antibodies to H. pylori generally indicate a possible infection, and if accompanied by digestive symptoms, such as gastric and epigastric discomfort with nausea, vomiting, abdominal pain or aggravation of existing diseases, early treatment is recommended. This germ is usually associated with acute and chronic gastritis, peptic ulcers such as gastric ulcer or duodenal ulcer, gastric cancer and other digestive system diseases; it can also be cross-infected in daily life by sharing utensils through diet, so regular treatment is recommended to prevent cross-infection. Treatment can generally be done by triple therapy, such as omeprazole, clarithromycin and amoxicillin, or quadruple therapy for about 10 days. Therefore, it is recommended to have regular gastroenterology treatment and gastroscopy if necessary; in addition, it is recommended to eat less spicy and irritating food, stay up less, drink less, eat more fruits and vegetables, and keep the bowel movement smooth, etc.; if there are no symptoms, it is recommended to review regularly.
