H. pylori does not affect pregnancy, H. pylori is present in the stomach and is highly infectious and can harm the health of the stomach, so it is the digestive system that is mainly harmed. However, pregnancy belongs to the reproductive system and there is little relationship between the two, so H. pylori will not affect pregnancy. Even if you are infected with H. pylori, you can still get pregnant without any problem. It is extremely unlikely that H. pylori can be transmitted through the placenta, so you don’t have to worry about transmitting it to the fetus in the womb. However, infection with this germ leads to stomach upset, which results in indigestion and poor appetite, leading to insufficient nutritional intake, which can affect the health of the fetus and the pregnant woman. Therefore, it is recommended that you can take clarithromycin capsules, colloidal bismuth salts and other drugs for treatment before pregnancy, usually pay attention to dietary hygiene, rinse your mouth in time after eating, and eliminate Helicobacter pylori bacteria before preparing for pregnancy.
