Gastroparesis is a condition in which the stomach muscles do not work properly. As a result, food empties from the stomach very slowly, or not at all. Children with this disorder may feel full all the time, be very nauseous, have pain or vomit undigested food left in the stomach.
What is Gastroparesis? In this group of uncommon disorders, patients suffer from symptoms which are suggestive of blockage (obstruction) of the stomach, yet investigations show no evidence of a mechanical blockage. The underlying problem is a disturbance of the hormonal and nervous control of stomach emptying. In most cases the cause is unknown.
