When a pregnant woman develops gastroenteritis, she needs to consult the obstetrics and gynecology department or the gastroenterology department, and the preferred department is obstetrics and gynecology. Obstetricians and gynecologists will routinely perform obstetrical examinations and instruct pregnant women to use probiotics to regulate their intestinal flora and to correct dehydration with rehydration if necessary. If the symptoms of gastritis, such as nausea and vomiting, are obvious and require the use of medication, the pregnant woman can register with a gastroenterologist instead and be treated with stomach-protective medication under the guidance of the gastroenterologist. However, for most stomach medications, including proton pump inhibitors and H2 receptor antagonists, almost all the instructions state that they are prohibited or used with caution in pregnancy and childbirth. In the case of obvious gastroenteritis, symptomatic medication should be given, and proprietary Chinese medicines that are not contraindicated for pregnant women can be used, such as rehabilitative new liquid, in consultation with a specialist.
