A positive result for Helicobacter pylori suggests that the patient is infected with H. pylori. H. pylori is mainly transmitted through the digestive tract, and H. pylori infection can be caused by unknowingly sharing utensils with an infected person, sharing a dish of food, or kissing an infected person; it can also be caused by accidental contact with feces containing H. pylori, or H. pylori contaminated food and water. Patients usually have no obvious symptoms in the early stage of H. pylori infection, but as the infection worsens, they may experience upper abdominal distension, abdominal pain, acid reflux, belching, and morning nausea, vomiting and other discomforts. If accompanied by Helicobacter pylori infection, it is necessary to use quadruple therapy for eradication under the guidance of professional physicians, i.e. 1 proton pump inhibitor, 1 bismuth agent and 2 antibiotics, commonly used are clarithromycin, amoxicillin, bismuth potassium citrate, omeprazole and so on. It is recommended to consult the doctor in time and carry out targeted treatment under the guidance of professional physicians.
