H. pylori Treatment in Seomyeon, Busan
H. pylori treatment is a course of antibiotics combined with acid-reducing medicine to eradicate Helicobacter pylori, a stomach bacterium linked to gastritis, ulcers and stomach cancer. In Seomyeon, clinics usually diagnose it during gastroscopy or with a urea breath test, then prescribe a 7–14 day regimen. A follow-up breath test at least four weeks after finishing confirms whether it worked.

What is H. pylori treatment?
Helicobacter pylori is a spiral-shaped bacterium that lives in the stomach lining. It is usually acquired in childhood and can persist for life. Many people have no symptoms, but it causes chronic gastritis and is a major cause of stomach and duodenal ulcers. Long-term infection is also a recognised risk factor for stomach cancer and a type of stomach lymphoma. Eradication treatment aims to clear the bacteria completely.
Who is it for?
- Anyone with a confirmed H. pylori infection, especially with ulcers or gastritis
- People with a family history of stomach cancer
- Those with persistent indigestion who test positive
- Patients with early stomach cancer removed endoscopically, or with gastric MALT lymphoma
- Long-term aspirin or anti-inflammatory users with a history of ulcers
What happens at the clinic
- Testing: during gastroscopy, a small biopsy is checked with a rapid urease test or examined under the microscope. Without endoscopy, a urea breath test or stool antigen test can be used.
- Medicine review: the doctor checks allergies, especially to penicillin, and other medicines that may interact.
- Prescription: you receive a combination of a proton pump inhibitor and antibiotics. Because resistance to some antibiotics, notably clarithromycin, is significant in Korea, doctors may choose bismuth-based or other regimens, sometimes guided by resistance testing.
- Completing the course: you take all doses for the full 7–14 days.
- Confirmation test: a breath test is done at least four weeks after finishing, with acid-reducing medicine paused beforehand as instructed.
Treatment outlook
A first course clears the infection in most people, and if it fails, a different regimen is used. Once eradicated, reinfection in adults is uncommon. Clearing the infection helps ulcers heal and prevents recurrence, and is associated with a lower risk of stomach cancer, though regular endoscopic screening is still recommended.
Risks and side effects
Common side effects include a bitter or metallic taste, nausea, diarrhea, bloating and dark stools with bismuth. Avoid alcohol if metronidazole is prescribed. Severe diarrhea, rash or allergic reactions should be reported promptly. Missing doses is the main reason treatment fails and resistance develops.
Choosing a clinic for H. pylori treatment in Seomyeon
- Ask which regimen is prescribed and why, given local antibiotic resistance.
- Confirm the clinic schedules a breath test to check eradication rather than assuming success.
- Ask whether resistance testing is available after a failed first course.
- Request clear written instructions on dosing times and food.
- Ask whether family members should be tested.
For residents and visitors
Plan to stay in Busan or arrange testing at home for the confirmation test four or more weeks later. Seomyeon clinics on the Line 1 and 2 interchange make the follow-up breath test a quick visit.

Frequently asked questions
How is H. pylori tested?
It can be detected from a stomach biopsy during gastroscopy, or without endoscopy using a urea breath test or stool antigen test. Blood antibody tests show past exposure but cannot confirm current infection.
How long does H. pylori treatment take?
Treatment courses typically last 7 to 14 days, depending on the regimen. A breath test at least four weeks after finishing confirms whether the infection has cleared.
What are the side effects of H. pylori treatment?
Common side effects include a bitter taste, nausea, loose stools and bloating. These usually settle after the course. Report severe diarrhea, rash or breathing difficulty to a doctor immediately.
Should my family be tested for H. pylori?
H. pylori often spreads within families. Testing is worth discussing for household members with stomach symptoms or a family history of stomach cancer. Your doctor can advise who should be tested.
What if the first treatment fails?
A second course with different antibiotics is used, sometimes guided by resistance testing from a biopsy. Taking every dose on time and avoiding missed doses improves the chance of success.
