Why do some fibroids cause constipation?

Fibroids can directly and indirectly cause constipation. The uterus lies directly in front of the distal end of the colon (i.e. rectosigmoid region). Fibroids that develop in the back of the uterus can press on the colon from the outside, and in some cases, cause significant constipation. Women that have fibroids that cause heavy menstrual bleeding can become anemic, which may require them to take iron supplements. These supplements often cause constipation.
