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.
Gastroparesis is a gastric motility disorder that is characterized by delayed stomach emptying in the absence of a mechanical obstruction. The characteristic symptoms of gastroparesis include nausea, vomiting, bloating and early satiety. Abdominal pain may be a prominent symptom in some patients. The diagnosis of gastroparesis requires ruling out other causes of nausea and vomiting, such as peptic ulcer disease, gastrointestinal infection, pancreatic disease, hormonal disorders and medication side effects. The most common cause of gastroparesis is diabetes.
