Flatulence in pregnant women does not directly affect the fetus. If a pregnant woman experiences bloating and distension for a long time, it may lead to loss of appetite, resulting in malnutrition and decreased immune function, which in turn can affect the development of the fetus. Pregnant women’s flatulence may be a normal reaction to pregnancy or incorrect eating patterns, or it may be caused by gastrointestinal indigestion, and patients usually suffer from a combination of nausea and belching. Pregnant women with gastric distension need to be treated promptly to avoid malnutrition affecting the growth and development of the fetus. It is recommended that patients improve their symptoms through dietary modifications, such as eating fewer and more frequent meals and avoiding foods that can easily cause flatulence, such as soy products and sweet potatoes. Medications can be chosen from stomachic and appetite tablets, but care should be taken under the guidance of a doctor to ensure the safety of the fetus. In addition, it is recommended that pregnant women eat a balanced diet and exercise properly during pregnancy to promote gastrointestinal motility, which helps digestion of food and fetal growth and development.
