It is possible to test for H. pylori the day after drinking alcohol, and the test results are usually not affected.
H. pylori is mostly found in the stomach and may cause gastritis, gastric ulcer, gastric cancer and other diseases. Clinical tests are usually performed through gastroscopy, carbon 14 or 13 breath test, blood antibodies, etc. There is no data showing that drinking alcohol the day before has an effect on the test results, but drinking alcohol may cause biochemical and other tests to be biased, and drinking alcohol the day before the test is generally not recommended.
When the test result of Helicobacter pylori is positive, it can be treated with a quadruple combination of drugs such as amoxicillin, clarithromycin, omeprazole and bismuth potassium citrate under the guidance of a doctor. The transmission pathway of Helicobacter pylori is mainly mouth-to-mouth, so it is necessary to share meals with family members during the period of treatment, to avoid infecting each other, and minimize going out to gather together for a meal.
