It is not normal for the test result to remain positive after one month of taking eradication therapy for H. pylori. Helicobacter pylori is an anaerobic bacterium, which can induce gastric diseases, and it is necessary to take Helicobacter pylori eradication therapy. If the result is still positive after taking H. pylori eradication treatment, it means that the eradication treatment has failed and another eradication treatment is needed, but at this time, the treatment program should be changed on the basis of the previous treatment, so as to avoid the emergence of drug resistance. If you are infected with H. pylori, you need to use chopsticks during meals to avoid cross-infection. If you are still positive after one month of H. pylori medication, it is recommended that you go to the hospital and have your doctor develop an individualized treatment plan based on your specific condition to avoid delays.
