It is recommended that pregnancy be possible 3 months after H. pylori treatment, depending on the doctor’s advice. The current H. pylori treatment regimen is quadruple therapy, which includes two antibiotics, a proton pump inhibitor, and a bismuth agent, and requires 2 weeks of continuous medication, such as amoxicillin, clarithromycin, omeprazole, and bismuth pectin. During the treatment of H. pylori, there is no complete guarantee that there will be no effect on the embryo and fetus, so pregnancy during treatment is not recommended. The medication is usually fully metabolized after three months, so it is recommended to get pregnant after three months of H. pylori treatment. It is also important to note that after 2 weeks of taking the medication, it is necessary to stop taking the medication for 4 weeks before reviewing the H. pylori test. Currently, C13 and C14 are the most commonly used methods, and C14 has a small amount of radiation, so it is recommended to choose C13. If C14 is used for review, it is recommended to get pregnant 3 months after the C14 test, but we will follow the doctor’s advice for specific cases. Treatment for H. pylori should be carried out under the guidance of a specialized doctor, who should be informed in advance if there is any idea of pregnancy.
