3 Questions About a Gastric Emptying Test

If a clinic orders a gastric emptying test, ask which test you are having before arranging the day.

Three questions before the appointment

1. What will this test measure? In a scan, you eat a meal containing a small amount of radioactive material, and a camera tracks it. In a breath test, a substance in the test meal is later measured in collected breath samples. Ask which method the clinician ordered and why.¹

2. Which health details do you need? Bring your prescriptions, over-the-counter medicines and supplements. Mention diabetes, previous digestive surgery and other relevant diagnoses. The diagnostic history includes these details, and some medicines can slow stomach emptying or produce similar symptoms.¹²

3. What preparation does this appointment require? Request the clinic’s written instructions for food, medicines and the test meal. Ask how long to reserve and whom to contact if an instruction is unclear. Have the clinical team specify any medicine changes before you make them.

Why there may be other tests

Blood or urine tests can check for associated problems such as dehydration. Endoscopy or imaging may investigate other explanations, including a blockage. Ask how the emptying-test result will be considered alongside those findings.¹

Symptoms that should not wait for testing

Seek medical help right away for severe abdominal pain, blood or coffee-ground material in vomit, prolonged vomiting, fainting or difficulty breathing. Dehydration signs, including reduced urination and light-headedness, also need medical attention.²
