Hi, my particular condition has little to do with food or digesting food as it can happen on a totally empty stomach. The esophageal sphincter closes or mostly closes and won’t relax. It is true that if there is excess stomach acid it makes things even worse but that isn’t the primary cause .
Perhaps examine these possibilities at Earthclinic.com to see if anything here may provide some relief:
