Featured: Gastric Emptying Study Main Article
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. A gastric emptying study often is used when there is a possibility of an abnormal delay in food emptying from the stomach. Medically, this is called delayed gastric emptying. Delayed gastric emptying symptoms are abdominal discomfort after meals, nausea and vomiting. The two most common causes of delayed gastric emptying are gastric outlet obstruction and gastroparesis.
