What is a G.I. Series?
An Upper G.I. series is an examination of the stomach, esophagus, and sometimes the small bowel. You are required to drink a liquid called barium for this exam.
How do I prepare for this exam?
You are to have nothing to eat or drink after midnight prior to your exam. Also, do not eat or drink anything the morning of your exam. If your stomach is not empty, the study will not be satisfactory or may be canceled.
Essential medication may be taken with a sip of water. If your are diabetic, please consult your doctor before taking any medication on the morning of your exam.
What will the exam be like?
You will be asked to change from your clothes to a hospital gown. A preliminary film will be taken of your abdomen to assure that you are properly prepared.
You will be taken to an X-ray room by a technologist. When the radiologist arrives, you will be asked to drink the barium. The barium fills your stomach and small bowel so they can be seen on X-rays. The radiologist will watch this on a special screen, periodically, films will be taken and you will be asked to change your position and hold your breath.
How will I learn the results?
You should contact your doctor for the results, not the Radiology Department.
When may I eat?
You may eat as soon as the exam is over. You should drink plenty of fluids to avoid constipation from the barium.
Remember:
- Tell your doctor or the technologist if your are pregnant or think you may be.
- Tell your doctor or the technologist if you have any allergies.
