Many pregnant women will have the symptom of dry stool during pregnancy. There are three main reasons for this: the first one is that as the fetus gradually increases, it will increase the pressure and cause the abdominal pressure to rise, which will lead to the slowing down of the peristalsis of the intestines, which will slow down the discharge of stool and cause dry stool after a long time. The second, because of the pregnancy, pregnant women eat more, eat more peristalsis and slow, will lead to food residues in the intestinal tract stay too long, so that too much water absorption, and lead to dry stool. The third one is that pregnant women exercise relatively little, and the gastrointestinal peristalsis will be even slower, thus leading to dry stools.
