Summary of Gastroparesis
Gastroparesis is a medical condition consisting of a paresis of the stomach, resulting in food remaining in the stomach for a prolonged time. Normally, the stomach contracts to move food down into the small intestine for additional digestion. The vagus nerve controls these contractions. Gastroparesis may occur when the vagus nerve is damaged and the muscles of the stomach and intestines do not properly function. Food then moves slowly or stops moving through the digestive tract.
