Gastroparesis is a disorder that affects the digestive system. During normal digestion, the stomach breaks down food and then contracts to push food down to the small intestine. With gastroparesis, there is delayed emptying of the stomach. Food either moves slowly through the digestive tract or does not move at all. This can pose problems since the food can harden causing blockage, nausea, and vomiting. Bacteria can also start to grow. Gastroparesis is a potentially serious condition. It requires care from your doctor.

Movement of food in the digestive system is controlled by the vagus nerve. Gastroparesis occurs when this nerve is damaged.
