I have been diagnosed with GP. Mine is considered idiopathic (unknown cause) since I do not have diabetes. If you are a diabetic controlling your blood sugar will help and in most cases cure GP. However, for people like myself, there is no cure or cause. I regurgitated food for over 5 years without a diagnosis. I still regurgitate food. Going on a liquid diet and making sure my bowels are moving helps me. I eat baby food, and almond milk with pea protein, and avoid meat. There are medications that claim they help. One that many find successful is Motegrity. I had serious side effects and had to stop this med after 5 days. It is an awful disease because every social event and every Holiday involves foods we cannot eat. Stay away from fried foods, dairy, and all Mexican food and cabbage. There are other foods that are not GP friendly. The list is extensive. It is very distressing and can leave you feeling isolated and alone. Usually, after I follow my liquid/baby food protocol for 3 days I can return to eating simple, nongaseous foods in small portions. Think white. Rice, potatoes, and bread. Think fish and nonfibrous veggies. I sincerely miss eating salads and all heart-healthy foods. Try to remain calm and seek help if you become dehydrated. I hope this helped a little. My sincere sympathy. Life is not easy with GP, but remain optimistic and work to find inner happiness in a world of nausea and stomach pain. Hugs!
