Gastric Emptying Study

Medical Author: Dennis Lee, MD
Medical Editor: Jay W. Marks, MD

What is a gastric emptying study?

A gastric emptying study is a procedure that is done by nuclear medicine physicians using radioactive chemicals that measures the speed with which food empties from the stomach and enters the small intestine. Gastric emptying studies are used for testing patients who are having symptoms that may be due to slow and, less commonly, rapid emptying of the stomach. The symptoms of slow emptying are primarily nausea, vomiting, and abdominal fullness after eating. The symptoms of rapid emptying are diarrhea, weakness or light-headedness after eating after eating.

Perhaps only 10% of those affected actually seek medical attention for their dyspepsia. Dyspepsia is not a particularly good term for the ailment since it implies that there is "dyspepsia" or abnormal digestion of food, and this most probably is not the case. In fact, another common name for dyspepsia is indigestion, which, for the same reason, is no better than the term dyspepsia! Doctors frequently refer to the condition as non-ulcer dyspepsia.
