During pregnancy, it is more common to experience constipation than frequent bowel movements, notes WebMD. This is most commonly caused by the slow transit of content through the bowels due to hormones, notes KidsHealth. The uterus also pushes against the bowels in late pregnancy, making constipation worsen.
Some other causes of this constipation include a lack of fiber in the diet and not consuming enough fluids, according to WebMD. Constipation also occurs after giving birth due to the consumption of antacids, iron supplements or pain medication given during labor.
If a woman has problems with constipation during pregnancy, a doctor may suggest eating more fiber, drinking more fluids and exercising regularly, according to KidsHealth. He may even recommend a stool softener.
