If a pregnant woman develops hemorrhoids, the first department to consult should be the anorectal department. However, if a pregnant woman needs to use medication for her hemorrhoids, the anorectologist should still communicate with the obstetrician and gynecologist in a timely manner to combine specific medications that can be used for pregnant women with those that can be used after consultation. The main reasons why pregnant women cause hemorrhoids or aggravate the symptoms of hemorrhoids in the course of pregnancy are also clinically common: 1. The process of pregnancy will lead to an increase in the blood volume of the pelvis; 2. The level of sex hormones will increase during pregnancy, which will cause vasodilation and tissue relaxation. 3. It is the fetal pressure that will lead to impaired local blood circulation.
