A colonic transit study is an aX-ray test that evaluates how quickly food passes (transits) through your digestive tract. In simple terms, this test is a measure of how much time it takes for food to pass from the stomach through the intestines into the rectum and out of the body as a bowel motion.
When will you be asked to undergo this test?
You will be asked to undergo this test if you suffer from chronic constipation.
What does the test entail?
You will be given 6 capsules, each of which contains 10 markers or components that can be seen on X-ray. You will be asked to swallow one capsule daily for six days at the same time (preferably morning) before the examination. The capsules are inert and are not absorbed in your gut and so they will pass through your stomach and intestines.
On the 7th day after taking the capsules, you will be asked to come back to the hospital and an X-ray image will be taken of your abdomen.
What precautions need to be taken?
You need to stop taking any tablets that affect your bowel movements during the duration of the test, including laxatives, stool softeners, and other drugs like codeine and iron tablets. You should discuss Dr. Hegde all the tablets you are taking so that she can advise you on which tablets you can continue taking. If for any reason, you are unable to stop your medication for six days, please call us.
You don’t need to follow any special diet before the examination. You can eat and drink as you do normally.
If you are premenopausal, you will be asked to fill the details of your last menstrual period so as to ensure that you are not pregnant at the time of the test.
Is there any risk of radiation?
The dose of X-ray that you will be exposed to in this test is minimal and is equivalent to the background radiation that you naturally are exposed to over a month.
