H. pylori mostly grows in the stomach, which can easily lead to gastritis, gastric ulcer and other diseases, and does not exclude the possibility of gastric cancer, “weak H. pylori” is considered to be a weak positive in the H. pylori test. A weak H. pylori positive test is mainly considered to be a mild H. pylori infection. It may also be a false positive during the monitoring process. The diagnosis should also be made in conjunction with clinical manifestations. If H. pylori infection, it can easily lead to the onset of chronic gastritis or gastric ulcer. If the stomach feels uncomfortable, stomach pain, black stool and other symptoms, gastroscopy is needed to clarify the cause and then the correct medication treatment. If the test is only weakly positive, and there is no obvious discomfort, you can temporarily do not do treatment, after a period of time in this laboratory tests to clarify whether the infection of Helicobacter pylori. However, you must pay attention to the maintenance of the stomach and lifestyle adjustments, diet should be regular, such as three meals a day to eat on time, do not eat cold food, leftovers, because H. pylori can be transmitted through the hands, unclean food, utensils, etc., so wash your hands before and after meals, to develop good habits of hygiene.
