Helicobacter pylori can usually be cured after about two weeks of treatment, but it depends on the patient’s condition and so on. If the patient is infected with Helicobacter pylori, it can be treated with a quadruple combination of amoxicillin, clarithromycin, omeprazole, bismuth potassium citrate, etc. The course of treatment is 10-14 days, and after a course of treatment, the medication should be stopped for one month, and then rechecked again to see if there is any infection of Helicobacter pylori, if the result of the rechecking is negative, then it represents that the Helicobacter pylori bacteria has been completely cleared. H. pylori is a kind of micro aerobic bacteria that is spiral or arc-shaped under the microscope, and patients may experience clinical symptoms such as abdominal pain, nausea, and loss of appetite. If the patient is still infected with H. pylori after review, the patient should take another course of oral medication after six months and adjust some of the medication regimen to prevent incomplete clearance of H. pylori due to drug resistance or some other factors. It is recommended that patients with H. pylori infection should strictly follow the doctor’s instructions for medication during the treatment period to avoid affecting the effectiveness of drug therapy, resulting in the inability to clear the H. pylori bacteria.
