HP is an acronym for helicobacter pylori. Helicobacter pylori is mainly parasitized in the pylorus of the stomach, sometimes in the form of a spiral, sometimes in the form of a rod, so it is called Helicobacter pylori, which is a kind of normal bacteria in the stomach. However, under certain circumstances, if the body’s resistance is relatively poor, or some other reasons lead to a large number of H. pylori bacteria multiply and cause disease, the clinic can detect H. pylori by carbon 13 or carbon 14 breath test. If the titer is greater than 700DPM or more, anti-HP treatment is needed, if it is less than 200DPM or less, it can usually be considered to continue clinical observation. If there is H. pylori infection, along with gastric ulcer, residual gastric cancer, and gastric erosion, gastric triple and gastric quadruple medications can be considered to be given for anti-HP treatment.
