Gastroparesis Causes

There are many different causes of Gastroparesis, although the connection between disorders is not completely apparent in many scenarios.

Complications from Abdominal surgery such as nissen fundoplication, gastric bypass surgery, and/or gallbladder removal. Surgery may injure the vagus nerve which is responsible for causing the stomach muscles to contract, pushing food out of the stomach. If the vagus nerve is damaged, it becomes paralyzed and is unable to perform this function. In some instances, post-surgical gastroparesis is temporary and the stomach returns to normal after healing but in many situations if the vagus nerve is badly damaged then the gastroparesis remains long term.

Diabetes is another cause of Gastroparesis. Other causes include some disorders of the nervous system, such as Parkinson’s disease, stroke, and some medicines, such as tricyclic antidepressants, calcium channel blockers, and opiate pain relievers.  Sometimes people get idiopathic gastroparesis for no known reason.
