Gastroparesis is an abnormally delayed peristaltic movement of the stomach. As a result, it takes this organ a much longer period of time to emptying its food contents into the small intestine. The symptoms of gastroparesis are nausea, bloating, and sometimes vomiting. This partial paralysis of the stomach can be caused by a viral infection that affects the autonomic nervous system, autoimmune disorders, anorexia nervosa, Parkinson's disease, etc.
In most countries, it is treated with a domperidone and simethicone.
