Pregnancy bloating does not mean fetal abortion, there is no correlation between the two. The increased secretion of estrogen, progesterone and HCG in a woman’s body after pregnancy may stimulate the gastrointestinal mucosa, resulting in slower gastrointestinal motility and indigestion, which may lead to nausea, vomiting and flatulence. In addition, the reduced activity during pregnancy may also slow down the gastrointestinal motility, which in turn may lead to bloating. Fetal arrest is mainly related to the quality of embryo and maternal factors. Generally, when fetal arrest occurs, most pregnant women have no obvious abnormalities, and some of them may have reduced early pregnancy reaction, which may be accompanied by vaginal bleeding, and generally do not show signs of stomach distension. If the HCG gradually decreases and the ultrasound reveals no growth or shrinkage of the gestational sac, the pregnancy should be terminated in time. Pregnant women with bloated stomach can do moderate activities, such as walking and slow walking, to promote gastrointestinal peristalsis and relieve abdominal distension. Eat a reasonable diet with less gas-producing foods, such as sweet potatoes, radishes, beans, etc. Eat fresh vegetables and fruits in moderation, and eat less spicy and stimulating foods.
