H. pylori is detected, know that it can cause disease, may be infectious, need to be eradicated, but “kill” after repeated treatment, even repeatedly, the retest is still positive, just “kill” can not be killed, how to do? Many patients are very confused. First of all, I think we should find out whether your H. pylori belongs to the range of “kill”, that is, the expert consensus that must be eradicated. For example, peptic ulcer, erosive gastritis, atrophic gastritis, post-operative gastric cancer, and family history of gastric cancer are all cases that should be eradicated. Therefore, if you have been tested for H. pylori infection, it is advisable to have a gastroscopy, unless you are younger than 45 years old and do not have any stomach discomfort or family history of gastric cancer. If you have been treated repeatedly, it is best to hold off on treatment for about 6 months, when the H. pylori can return from a curly spherical shape to an antibiotic-sensitive rod shape, which is relatively easy to eradicate. Retreatment, that is, remedial treatment, must be careful, according to the previous treatment, to develop a personalized treatment plan, such as combined medication, extended courses of treatment, new use of old drugs, a combination of Chinese and Western medicine, or completely can strive to eradicate H. pylori. If the test is still not eradicated, and the test is still “positive”, you can not be nervous, we can still use other methods of treatment. It is not true that you can’t treat your stomach disease without eradicating H. pylori. In short, if you do use all the methods, it is not recommended to repeatedly use a large number of antibiotics without certainty, which will only increase drug resistance and bring side effects.
