What about Helicobacter pylori?

Helicobacter pylori is found in the stomach. It is a bacterium that damages the gastric mucosa. It mainly parasitizes the gastric antrum and pyloric area. It is directly related to gastritis, gastric erosion, peptic ulcer and even gastric cancer. When Helicobacter pylori infection is found in the stomach, it needs to be eradicated by quadruple therapy. At this stage, amoxicillin, clarithromycin, colloidal bismuth pectin and omeprazole are commonly used in clinical treatment. The course of treatment is 14 days. If the patient is allergic to amoxicillin or shows resistance to clarithromycin, he/she can be switched to antibiotics such as levofloxacin lactate or furazolidone. The course of treatment is the same, for 14 days. After stopping the drug for more than 14 days, the carbon 14 breath test will be repeated to determine whether it will be eradicated. If gastritis, gastric erosion and peptic ulcer caused by Helicobacter pylori infection are eradicated, drugs that inhibit gastric acid and protect gastric mucosa need to be used after the bacteria are eradicated.
