Can having a fibroid on the posterior of the uterus cause problems with bowel movements?

Yes: If the fibroid is large and compressing the colon or rectum it can cause problems with bowel movements. Schedule a visit with an Obgyn for an examination and ultrasound.

Fibroids: At 51, you are statistically still producing estrogen, which makes fibroids grow larger over time. The size of a fibroid can cause difficulties with bowel function by pressing on the colon. Obtain a sonogram to estimate the size of the fibroid. They can of course be removed surgically or by obstructing blood flow to the womb.
