Pregnant women can’t get rid of flatulence mostly due to the weakened gastrointestinal function of women during pregnancy, resulting in the inability to expel gas in the intestine in time, which is usually a normal physiological manifestation. However, it may also be related to improper diet or gastrointestinal diseases, so we need to identify the causes and deal with them in a targeted manner. I. Physiological reasons: 1. hormonal changes: in early pregnancy, the level of hormones in the body of pregnant women usually changes, so that intestinal peristalsis slows down and the gas in the intestine can not be expelled smoothly; 2. compression of the intestine: as the fetus grows, the uterus will expand to compress the intestine, which will also make the intestine not easy to peristaltic, flatulence is not easy to expel; 3. diet: if the diet of pregnant women prefer high protein and high fat, they are also prone to constipation, bloating, flatulence can not be expelled. The problem of bloating and flatulence can not be discharged. Second, pathological reasons: pregnant women with gastrointestinal disorders, such as indigestion, gastritis, etc., may lead to a weakened ability to digest food, while pregnant women are often accompanied by a weakened intestinal peristalsis, there will be flatulence can not be discharged from the performance. Therefore, it is recommended that pregnant women eat less and eat more, chew slowly, and supplement their diet with more fiber-rich vegetables and fruits, such as leeks, spinach, celery, apples, etc. Also pay attention to drinking more water and taking appropriate walks and activities every day to help defecation and exhaustion. If pregnant women have gastrointestinal diseases such as gastritis, it is recommended that they seek medical attention and treatment under the guidance of a doctor.
