The symptoms of gastroparesis are best understood in the context of the physiology of gastric emptying (GE). The stomach functions as a reservoir for food and nutritional content, which are broken down to produce chyme.

It usually does not develop until less than 2 m (6.6 ft) of the normally 6.1 m (20 ft) small intestine remains. [1] [3] Treatment may include a specific diet, medications, or surgery. [1] The diet may include slightly salty and slightly sweet liquids, vitamin and mineral supplements, small frequent meals, and the avoidance of high fat food. [1]
Other common symptoms that stomach disease might cause include indigestion or dyspepsia, vomiting, and in chronic disease, digestive problems leading to forms of malnutrition. [ 5 ] : 850–853 In addition to routine tests, an endoscopy might be used to examine or take a biopsy from the stomach.
