Upper Gastrointestinal Exam (UGE)

UGI is a noninvasive X-ray exam of the pharynx, esophagus, stomach and duodenum (the first part of the small intestine).

UGI helps doctors diagnose and treat medical conditions of the small intestine.

X-ray images are taken while the patient drinks flavored barium sulfate, which allows the radiologist to see the digestive tract on a fluoroscopic screen.

You will be asked to remove some or all clothing, wear a gown, and remove jewelry, eyeglasses, dentures, metal objects, etc. During the exam you will need to stay still and hold your breath when instructed. In what’s called a “double contrast” UGE, the patient will swallow baking soda crystals while the X-rays are taken. This can cause bloating and gas.

The test itself usually takes about 20 minutes. After the exam, you can resume a regular diet and take your normal medications unless told otherwise. For 48-72 hours afterward, your stools may appear grey or white and you may temporarily experience constipation. An over-the-counter laxative can help with symptoms.

Your doctor will give you written instructions prior to your exam. Inform your physician of any allergies, recent illnesses or medical conditions, or if you are or could be pregnant. The stomach must be empty of food, so no food or drink (including regular medications) before the exam. Do not chew gum or smoke after midnight on the day before your procedure.
