I went to the Mayo Clinic in Rochester, MN to get my diagnosis, as I went through many tests and such here in VA to no avail. Mayo had a test they did (only 6 places in the world do it), that verified my colonic inertia. Was not a pleasant test, the day before the test I had to do a bowel cleanout. The day of the test a gastro insterts a thin plastic tube throughout your colon and then threads a small wire inside it that can measure colon peristalsis. I had to lay still for six hours as readings were constantly taken showing colon activity. At one point you are given a drink that has like 1,000 calories to test colon response. Later, I was given an injection of Neostigmine (a powerful bowel stimulant) and readings were taken. It is much more accurate than the marker test. My colon did not pass the test (no suprise there) and if I had not been having all the other symptoms I had been having (nausea, vomiting at least ten times daily, pain, and fainting) that one test would have been sufficient to have my colon removed (I had to have many more tests due to my symptoms). So at Mayo, one test is needed. Unfortunately it is not possible for everyone to take the time and money to go to Mayo. At the best hospital in my area here in VA, two tests were required, the sitz marker test and a defecogram (that rules out pelvic floor disorder as being the cause of constipation). I cannot imagine you would have to do many tests if your only problem is the constipation. Everywhere is different though, and even two different doctors at the same hospital may do different things. Don't stress about it, ultimately your physician will want to put you out of your misery. Stay positive! Let us know how your visit goes tomorrow, too. Good luck!!!!!!
