Upper Gastrointestinal (UGI)

You will be given a barium solution to drink. This allows the stomach to be more visible on the X-rays.

To ensure the best images, your stomach must be empty of food. Do not eat or drink anything after midnight (12:00 a.m.) the night before your exam. In the morning you can have no breakfast or water. If you must take oral medications, please take them with a minimal amount of water, or you may bring your medication to the office and take immediately following the study.

NOTE FOR PEDIATRIC PATIENTS: Infants must be able to bottle-feed. You must bring a clean empty bottle to the office the day of the exam.
