Will Helicobacter pylori be reinfected after radical treatment?

There is a possibility of reinfection after eradicating Helicobacter pylori, but the probability is low. Helicobacter pylori infection is usually related to factors such as dietary hygiene and close contact, and preventive measures should be taken after eradication. The probability of reinfection after eradicating Helicobacter pylori is usually less than 10%, which is more common in situations where hygiene conditions are poor or there are infected individuals in the family. The standardized cure plan includes a quadruple therapy of proton pump inhibitors combined with two antibiotics and bismuth agents, such as amoxicillin capsules, clarithromycin tablets, colloidal pectin bismuth capsules, etc., which can effectively eliminate bacteria. After treatment, successful eradication should be confirmed through carbon-13 or carbon-14 breath tests to avoid false recurrence caused by incomplete treatment. In daily life, serving of individual dishes, tableware disinfection, avoiding raw food and other measures can significantly reduce the risk of reinfection. In rare cases, Helicobacter pylori may recur due to factors such as drug-resistant strains or immune deficiencies. If symptoms such as upper abdominal pain and acid reflux occur after radical treatment, it is necessary to promptly undergo a breath test. People at high risk of recurrence include children, healthcare workers, or those who have been taking nonsteroidal anti-inflammatory drugs for a long time. Regular screening is recommended for these populations. The treatment of reinfection requires adjusting the antibiotic regimen based on drug sensitivity testing to avoid repeated use of the same medication. After the cure, good personal hygiene habits should be maintained, and family members should be screened and treated simultaneously. Avoiding spicy and stimulating foods in diet and supplementing probiotics such as yogurt in moderation may help maintain a balance of gut microbiota. If gastrointestinal symptoms recur, it is recommended to seek medical attention promptly for targeted examinations.
