What causes hemorrhoids in pregnancy?
Hemorrhoids, swollen veins in or around the rectum, are a common complaint during and after pregnancy. A form of varicose veins, they are caused by the increased pressure exerted on your veins by the weight of your uterus. During labor, the extreme strain of pushing your baby out also may lead to the formation of hemorrhoids. Once you've got them, these swollen veins can be made worse by constipation.
