A normal pylorus may mean that the H. pylori value is within the normal range, or it may mean that the mucosa of the peripheral pyloric region is normal and the pylorus opens and closes normally under gastroscopy. H. pylori can be measured by carbon 13 and carbon 14 breath test, the normal range of carbon 13 breath test is (0~4) dpm/mmol, and the normal range of carbon 14 breath test is (0~100) dpm/mmol, so pyloric normal may mean that the value of H. pylori is within the normal range. In addition to this, a normal pylorus can also be found in the gastroscopy report card. The pylorus is a part of the stomach, and a normal pylorus suggests that the mucous membrane surrounding the pyloric region is normal and that the pylorus opens and closes normally. If the results of gastroscopy or H. pylori test are abnormal, it is recommended to go to the hospital.
