I had that same problem for about 5 months. They tested me for ulcers, bacteria infection, acid reflux etc. They finally found that is was a problem with my gall bladder. You may want to get test done in these various areas to see what it could be. Good Luck!
Thank you for the suggestions, I am just about ready to beg my doctor for a referral. I haven't tried ginger before, I will definitely see if that helps me. Does it matter on how much ginger or how to ingest it?
Ginger is good for nausea and going for a brisk walk can help.
You could always try a bland diet for a while and see if it's related to the types of food you're eating. Since it's happening every time you eat (post-prandially), you might want to visit your Doctor and get a referral to a Gastroenterologist. Hopefully, they'll be able to find and fix the problem.
Good luck and God bless,
Sam
