During pregnancy, women need more nutrients and eat more than usual due to the development of the fetus, and they are less mobile and less active, which can easily lead to constipation. If a pregnant woman has severe constipation, it will have certain effects on the fetus. For example, it can cause miscarriage, premature birth and normal development of the fetus. Constipation in pregnant women often leads to hemorrhoids or aggravates the appearance of hemorrhoids, and when constipation is particularly difficult to defecate, it may even lead to intestinal obstruction. The presence of intestinal obstruction can induce fetal miscarriage, or fetal miscarriage can occur when the bowel movements are particularly forceful. If a pregnant woman is often constipated during pregnancy, the growth and development of the fetus will also be affected, because the constipation of a large amount of stool accumulation in the rectum will compress the uterus, resulting in fetal distress symptoms, which is not conducive to the growth and development of the fetus.

Therefore, pregnant women must take care of their intestines and try to avoid constipation.
