Gastroparesis is a disorder in which the stomach takes too long to empty after eating. The delay is caused by damage to the stomach nerves and results in bloating, heartburn, and possibly serious symptoms because digestion is altered.
Diabetes is the most common cause of gastroparesis. Other causes include some disorders of the nervous system, such as Parkinson's disease and stroke, and some medicines, such as tricyclic antidepressants, calcium channel blockers, and narcotics.
Symptoms are intermittent and most often occur during and after a meal. They include:
Symptoms range from mild to severe. Severe symptoms of gastroparesis may improve with treatment using medicines that help the stomach empty more quickly (motility agents). In very severe cases, a feeding tube placed in the small intestine may be needed.
