With a colonoscopy
the doctor will not be able to see your fibroids. The colonoscopy is to evaluate the inside your large bowel with a camera, and to check why you have blood coming through your rectum. If your doctor suspects an ulcer due to the amount of ibuprofen
you are taking, it seems that he will also do an upper endoscopy
to look into your stomach, which is the most common place for ulcerations.
Fibroids can be checked with imaging studies such as an ultrasound
, CT scan, etc. Try to decrase the amount of ibuprofen and motrin, and consider taking a pill to protect your stomach from ulcerations such as ranitidine
