Gastroparesis also called delayed gastric emptying, is a medical condition consisting of a partial paralysis of the stomach, resulting in food remaining in the stomach for an abnormally long time.Normally, the stomach contracts to move food down into the small intestine for additional digestion. Vagus nerve stimulation is an attractive therapeutic modality for gastroparesis, but prior methods required invasive surgery. Altered vagal nerve action can also contribute to poor motility, which may be seen in conditions like IBS, functional diarrhea, and functional constipation. .
