Also known as delayed gastric emptying, gastroparesis is the more accurate term because the older name fails to adequately describe completely the motor impairments that can happen within the stomach. There is not even expert agreement on the use of the main term; some reserve it solely for grossly impaired stomach emptying. Regardless, gastroparesis is the name of a clinical syndrome characterized by slow, sluggish emptying of solid food from the stomach, or more seldom, liquid nutrients as well, causing persistent digestive symptoms, particularly nausea, abdominal pain, reflux, bloating, early feelings of fullness, and vomiting. It primarily strikes in young to middle-aged women, but younger children and males may also have gastroparesis. Diagnosis relies on a radiographic gastric emptying exam. The two largest groups of gastroparesis patients have diabetes, and those with idiopathic cases, or cases for which there is no known cause.
