Helicobacter pylori was classified as a Group 1 carcinogen by the International Agency for Research on Cancer (IARC), part of the World Health Organization, back in 1994, and it is the most important modifiable risk factor for stomach cancer. The good news: eradicating it usually takes nothing more than a 14-day oral medication regimen. In China, the path from a breath test to a prescription can be completed within days; apart from a gastroscopy biopsy, the entire process is non-invasive, and the combined cost of testing and treatment for most patients comes to a few hundred to just over one thousand RMB (about US$70–200) — well below typical out-of-pocket prices in Western countries.
This guide is written for foreign patients and families considering H. pylori testing or treatment in China. It covers three things: how to get tested, how it is treated, and what it costs.
H. pylori: the clearest modifiable risk factor for gastric cancer
H. pylori is a bacterium that colonizes the stomach lining, causing chronic gastritis and closely linked to peptic ulcers, gastric MALT lymphoma, and stomach cancer. IARC classified it as a Group 1 carcinogen (carcinogenic to humans) in 1994, and research since has repeatedly confirmed that it is the primary cause of non-cardia gastric cancer and that eradication therapy reduces gastric cancer risk.
Infection rates in China are markedly higher than in most Western countries: epidemiological data show that roughly 40–50% of Chinese adults carry H. pylori, with a slow downward trend in recent years. This is precisely why Chinese physicians have extensive experience screening for and eradicating this bacterium — the testing and treatment you receive in China takes place in a setting with a large infection base and mature clinical pathways.
What does an infection feel like?
Most infected people have no noticeable symptoms, which is one reason it spreads so easily within households. Some people experience:
Dull upper abdominal pain, bloating, belching
Acid reflux, nausea, loss of appetite
Recurrent indigestion
Symptoms of peptic ulcer (post-meal pain, night pain)
To be honest: being infected with H. pylori does not mean you will get stomach cancer — the vast majority of infected people never develop it. But the mainstream medical consensus is "test positive, no contraindications, treat," particularly for people over 40 and those with a family history of gastric cancer.
Choosing among the three main testing methods
International patients most commonly use one of three testing routes, each suited to a different situation:
| Testing method | Reference price (RMB) | Features and who it suits |
|---|---|---|
| C13 urea breath test | approx. 150–250 RMB | No radioactivity, high accuracy, suitable for children and pregnant women; most common |
| C14 urea breath test | approx. 50–150 RMB | Cheaper, contains a trace of radioactivity; not suitable for pregnant women or children |
| Gastroscopy biopsy | Included in gastroscopy fee | Also assesses gastritis, ulcers, and early cancer; suits those who need a gastroscopy anyway |
Stool antigen testing is available at some hospitals as a non-invasive alternative, especially for screening infants and young children. If you have an independent indication for gastroscopy (chronic dyspepsia, alarm symptoms), a biopsy during the procedure handles "assessment + testing" in one go; if you simply want to know whether you are infected, the breath test is the fastest and most cost-effective choice.
Preparing properly for the breath test
The most common cause of a false-negative breath test is not the technology — it is inadequate preparation:
Stop proton pump inhibitors (PPIs such as omeprazole or esomeprazole) for at least 2 weeks before the test
Stop antibiotics and bismuth for at least 4 weeks before the test
Fast on the day of the test, or wait at least 2 hours after eating
If you are taking acid-suppressing medication or have recently used antibiotics, tell the doctor when booking; otherwise the result may be unreliable and the trip wasted.
The standard eradication regimen: 14-day bismuth quadruple therapy
The Chinese H. pylori Infection Treatment Guideline (2022) gives a strong recommendation for both first-line and repeat treatment: a bismuth-containing quadruple regimen for 14 days. The four components, taken twice daily, are:
A proton pump inhibitor (PPI) — suppresses stomach acid
A bismuth agent — protects the gastric lining and helps kill the bacteria
Two antibiotics — the eradication workhorses
The 14-day regimen achieves significantly higher eradication rates than the 10-day version; with proper adherence, the success rate reaches about 90%. Even if symptoms disappear quickly, take the full course at full doses — stopping early is one of the most common causes of treatment failure.
Resistance and individualization: no one-size-fits-all regimen
Antibiotic resistance is the key variable affecting eradication rates. Six antibiotics are commonly used in China: amoxicillin, clarithromycin, levofloxacin, furazolidone, tetracycline, and metronidazole. Resistance to clarithromycin, levofloxacin, and metronidazole is relatively high, while resistance to furazolidone and tetracycline remains low — one reason the bismuth quadruple regimen still performs so well in China. The World Gastroenterology Organisation makes the same recommendation: when clarithromycin resistance exceeds 15% or is unknown, first-line therapy should be bismuth quadruple.
For patients who have failed treatment more than once, some centers offer H. pylori culture with antibiotic susceptibility testing, using the results to guide second- and third-line therapy. Whether individualized susceptibility testing is worthwhile is a decision your doctor makes based on your medication history.
Costs: what testing plus treatment adds up to
Below are reference ranges for 2026; actual prices vary by city, hospital tier, and drug brand:
| Item | Reference range (RMB) | Approx. USD |
|---|---|---|
| C13 breath test (per test) | 150–250 RMB | US$21–35 |
| C14 breath test (per test) | 50–150 RMB | US$7–21 |
| 14-day quadruple therapy medications (mainly generics) | approx. 100–300 RMB | US$14–42 |
| Regimen including an imported PPI | approx. 500–1,000 RMB | US$70–140 |
Counting registration, the initial consultation, testing, and the confirmatory retest, most patients spend a few hundred to just over one thousand RMB in total (about US$70–200). For comparison, that amount would not even cover one specialist copayment in many Western health systems.
Confirming eradication after treatment
You cannot retest immediately after finishing the medication — the drugs temporarily suppress the bacterial count, producing false negatives. The correct approach:
Retest at least 4 weeks after finishing treatment
Stop PPIs for at least 2 weeks and antibiotics/bismuth for at least 4 weeks before the retest
Prefer a C13 breath test or stool antigen test
Only a negative confirmatory test completes the eradication. If the retest is still positive, the doctor will usually switch the antibiotic combination and move to second-line treatment.
Household co-treatment: why family members should be tested too
H. pylori spreads mainly via the oral-oral route between people living together long term, so "one person positive, the whole family screened" is a common scenario. Chinese gastroenterology consensus promotes household co-management: adults living with a positive patient should be tested, those positive treated, and shared meals, serving chopsticks, and similar habits encouraged to reduce the risk of re-infection after treatment.
A practical approach for international patients: complete testing and treatment yourself in China while family members living with you get tested either at home or during a trip to China.
The international patient pathway: done in days
For patients who do not need a gastroscopy, the whole process can be very compact:
Pre-trip teleconsultation: submit your history and current medications; the doctor assesses whether you need to stop any drugs first
Day of arrival: see the gastroenterology or international clinic and complete the C13 breath test
Within 1–2 days: receive the eradication prescription and medication guidance; you can take the medicines home
Four weeks after finishing: retest with a breath test, either at home or on a return trip to China
Everything except a gastroscopy is non-invasive, and most international patients complete testing and prescriptions within 2–3 working days in China. If you also need a gastroscopy evaluation, see our painless endoscopy page or our complete gastroscopy vs colonoscopy guide. Patients from countries covered by the visa-free transit policy can arrange a compact trip using the 240-hour visa-free transit.
Honest limitations and FAQs
Treatment is not 100% successful: even with correct adherence, about 10% of patients fail first-line treatment and need a different regimen.
Side effects are real: during the course you may notice a metallic taste, nausea, diarrhea, or black stools (caused by bismuth and harmless); most people tolerate them fine.
Tell the doctor about penicillin allergy: amoxicillin in the regimen will need to be replaced.
Re-infection is uncommon but possible: annual re-infection rates after successful eradication are low; household co-management and shared-meal hygiene reduce it further.
Not every stomach complaint comes from it: symptoms do not always disappear completely after successful eradication; a gastroscopy may still be needed.
