Gastroparesis is a disorder in which the muscles in the stomach and the intestine do not work normally, causing food to move slowly or to stop moving through the digestive tract. This can prevent your stomach from properly emptying after you eat.
One of the most common causes of gastroparesis is diabetes, though it may also be caused by stomach surgery, viral infections, certain medications, or metabolic disorders.
Symptoms of gastroparesis, which range in severity, include heartburn, pain in the upper abdomen, nausea, bloating, gastroesophageal reflux, or lack of appetite.
