I had the GES this week and got a gastroparesis diagnosis. I have to see the doctor to find out what to do. I went on the Livestrong website. It's not very encouraging. I also have silent reflux, type II diabetes and kidney disease. I hope the silent reflux goes away with treatment. Feeling like you have postnasal drip 24/7 is not fun, along with the constant throat clearing and coughing. The vagus nerve can be damaged by other things like chronic constipation. The way to deal with it is through a drastic change in your diet and meds like Reglan. Hope this helps.
