Gastroparesis

Gastroparesis is a condition in which the stomach empties its contents into the small intestine more slowly than normal, without any blockage. It causes bloating, nausea, vomiting of undigested food, upper abdominal discomfort and feeling full after just a few mouthfuls. Long-standing diabetes is a common cause, through damage to the nerves controlling the stomach. A gastric emptying study confirms it.
