Flatulence in pregnant women has no effect on the fetus, so pregnant women can rest assured. For most pregnant women, especially in early pregnancy may appear abdominal bloating, nausea, vomiting, loss of appetite and other symptoms, mainly with the pregnant woman’s body hormone level changes. If the flatulence is not obvious, most can be relieved by themselves, but if there are serious symptoms of upper gastrointestinal discomfort, leading to malnutrition, it is recommended that pregnant women should go to the hospital, and if necessary, to give the infusion of nutritional fluid treatment. However, for ordinary early pregnancy reaction or ordinary stomach bloating, there is no effect on the fetus. It can not be ruled out that there are a small number of pregnant women who have gastric diseases before pregnancy, such as chronic gastritis or gastroesophageal reflux disease, etc., after pregnancy the clinical symptoms of the above diseases may significantly worsen, but can not eat the drugs as much as possible do not take, because the drugs may affect the fetus.
