This research study is tracking how stomach bacteria (H. pylori) are becoming resistant to antibiotics over time in Korea. Researchers are examining bacterial samples collected from patients who have had this infection, looking at which antibiotics are becoming less effective and why. This information will help doctors choose better treatment plans in the future.
When antibiotic resistance develops, treatments that used to work stop working, leading to treatment failures. By understanding which antibiotics the bacteria are resisting and how these patterns are changing, researchers can help develop better strategies to treat this infection more successfully.

If you qualify, you will undergo an endoscopic procedure (where a thin camera is passed down your throat) to collect bacterial samples from your stomach. These samples will be sent to a laboratory where researchers will test them against various antibiotics to see which ones the bacteria resist. You may be contacted periodically as part of this long-term tracking study, but there are no ongoing medications or visits required after the initial sample collection.
