Gastric Emptying Scan at UPMC Susquehanna
Gastric emptying scans determine and measure gastric motility disorder, especially in patients with symptoms of nausea, bloating and abdominal pain. This scan evaluates the effect of medication or surgical intervention on gastric motility.
Preparing for a Gastric Emptying Scan
You will need to fast for eight hours, and abstain from smoking before the test and during the test. Your physician should have been informed that certain medications affect the test. If you take some of these medications, you will be instructed not to take them two days prior to the test. Please follow your doctor’s instructions. Please bring your list of medications. If you are diabetic, please monitor your blood sugar the day of the test.
If your blood sugar is greater than 275 mg/dl, call our office at (570) 321-2400 to reschedule the test. You will be in our department for four hours. It may help to bring a book, iPod, or Kindle, to occupy your time.
