I am a 34-yr-old female diagnosed with iron deficiency anemia two years ago. gi has not recommended colonoscopy. should i be concerned?

No: most females of child bearing age who are iron deficiency can attribute it to their menses. if you are not having GI symptoms or black or bloody stools, I would see that as appropriate.

Yes. Get checked.: If you have iron deficiency anemia, there can be several causes: 1) Diet-you could be iron deficient if you are a vegetarian 2) Heavy periods or irregular vaginal bleeding 3) GI bleeding from gastritis (inflammation in your stomach) or a growth in your colon. I would recommend checking stool cards for occult (microscopic) blood. If these are positive, you definitely need a colonoscopy.
