If you often have stomach discomfort, bloating, vague abdominal pain and other indigestion, and you are found to have H. pylori infection, it is recommended to visit a gastroenterology specialist. However, this test is generally inaccurate when H. pylori antibodies are detected in the blood. It is recommended to do a carbon 14 or carbon 13 breath test to clarify the presence of H. pylori infection. Before testing for H. pylori, you should not take proton pump inhibitors or antibiotic drugs for one month. If you take these drugs and go straight to the H. pylori test, the value may be inaccurate. If H. pylori infection is clearly established, it is still necessary to see a gastroenterologist. If there is a combination of pyloric ulcer or a family history of tumor, or if the stomach discomfort is more severe, eradication of H. pylori is recommended. Usually after 10-14 days of treatment, it is recommended to stop the medication for one month and then recheck whether H. pylori has been eradicated to avoid recurrent episodes of gastric disease. Therefore, H. pylori testing is a common and general test in gastroenterology and should be treated by a specialist.
