Is anyone with a VP shunt also experiencing GERD, gastric dumping, etc

In 2008, a ventriculoperitoneal shunt was implanted in my head to drain excess cerebrospinal fluid (from intercranial hypertension) and a hole in the base of my skull was plugged to stop a CSF leak. The shunt catheter was placed in my lower abdomen and ever since I've had chronic diarrhea, bowel urgency, gastric dumping, ulcers and gastritis, GERD/heartburn, and other digestive issues. In 2016, the shunt and catheter were replaced and the catheter was redirected to my upper abdomen so that it ends near my liver. This year, with a new neurosurgeon, the shunt has been reset twice and the headaches and visual disturbances have stopped. I am interested to know if other shunt patients have had GI problems and what was done to correct those problems.
