Further evaluation can be done with a lower endoscopy, either a colonoscopy or flexible sigmoidoscopy. This test can exclude anatomical causes leading to your symptoms, or a mass.
I would also consider blood tests to exclude thyroid disease, which also can lead to constipation.
Another GI opinion can be sought if the diagnosis continues to be non-revealing.

Also, I had the flexible sigmoidoscopy back in July of this year. Had some inflammation but nothing to be concerned about. And the colon did have a slight turn near the end but......... back at square 1 I guess!
I also have been on Synthyroid since I was 14 and was told that I would NEVER be able to go off this medication.
I had a colonoscopy the first of this year and that's why the G astrologist said all he could tell me was that my colon was over 6' long and that it was just going to take "time" for my food to be digested and disposed of properly or take Miralax and other over the counter stimulates to help me.
I have aslo done what they call a "pellet test" where you swallow about 4-5 pellet type pills and watch them after about 2 days to see where they are within the digestive tract but mine went through the tract fine. We are repeating this test in the upcoming weeks before any type of colon reduction surgery is considered.
Any other suggestions doctor?
