How do I prepare for an upper GI or a lower GI test?
Follow your doctor's instructions. You'll probably need to go on a low-fiber diet for two to three days before the test, not smoke for 12 to 24 hours before the test, skip certain medications for up to 24 hours before the test, and not eat anything for 12 hours before the test. You may also need to take oral laxatives and an enema the night before the test.
