Pregnant women who are constipated after straining to defecate will have an impact on the fetus, and may even cause fetal miscarriage and other adverse consequences. Early in pregnancy, the fetus is not stable, pregnant women are mostly in bed rest, less movement, gastrointestinal peristalsis slows down easily caused by constipation. If you force to defecate, it will lead to uterine contraction, causing preeclampsia. In the later stages of pregnancy, the gradual descent of the head of the fetus will cause pressure on the rectum, which may lead to rectal dilatation, which in turn presses the uterus and affects the development of the fetus. If the pregnant woman often exerts herself to defecate, the pressure in the abdominal cavity increases, which may cause the fetus to suffer from hypoxia, bradycardia, or even cause fetal malformation and other serious conditions. If constipation is more serious during pregnancy, straining to defecate may also lead to rectal prolapse and necrosis, aggravate intrauterine infections, and even lead to intrauterine death of the fetus, so it is necessary to pay great attention to it. When constipation occurs during pregnancy, it is recommended to drink a glass of warm water or honey water in the morning on an empty stomach, eat more fresh fruits and vegetables, and exercise appropriately to promote gastrointestinal peristalsis and improve the symptoms of constipation.
