There are two types of increased H. pylori antibody tests: one is clear that there is a present infection; the other is that there has been an infection, but it is not certain whether it is currently infected. The details are as follows: 1. Clear infection: If the H. pylori antibody test is elevated, along with nausea, vomiting, stomach pain and discomfort, decreased appetite and other digestive symptoms, it is generally clear that there is H. pylori infection. It is often treated by medication, and there will be slight differences in medication depending on the condition. Patients with ulcers should be treated with triple or quadruple radical therapy in combination with proton pump inhibitors plus antibiotics, if available. Please consult a professional doctor for guidance on the specific use of drugs; 2. Unclear infection: If it is unclear whether the current infection is present, endoscopy, H. pylori antigen test, urea breath test, etc. can be added for confirmation. If there is no infection, there is no need for treatment, regular check-ups can be done; if there is an infection, medication can be used according to the treatment recommendations after clear infection. During the treatment period, avoid overeating and avoid eating spicy, greasy and irritating foods such as fried and pickled foods. Diet should be based on light and easily digestible food, you can eat more easily digestible pasta as well as vegetables, fish and meat, etc., to maintain the regularity of life.
