Overview
Other Diagnostic Studies
Upper Endoscopy
After giving you a sedative to help you become drowsy, the doctor passes a long, thin tube called an endoscope through your mouth and gently guides it down the throat, also called the esophagus, into the stomach. Through the endoscope, the doctor can look at the lining of the stomach to check for any abnormalities.
Breath Test
After ingestion of a meal containing a small amount of isotope, breath samples are taken to measure the presence of the isotope in carbon dioxide, which is expelled when a person exhales. The results reveal how fast the stomach is emptying.
SmartPill
Approved by the U.S. Food and Drug Administration (FDA) in 2006, the SmartPill is a small device in capsule form that can be swallowed.The device then moves through the digestive tract and collects information about its progress that is sent to a cell phone-sized receiver worn around your waist or neck. When the capsule is passed from the body with the stool in a couple of days, you take the receiver back to the doctor, who enters the information into a computer.
