What causes gastroparesis?
Gastroparesis occurs when the nerves or muscles to the stomach are damaged or don't work. Diabetes is one of the most common causes. 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 opioid pain relievers. This condition can also be a complication of gastric surgery.
