The problem is I have he symptoms all the time. It doesn't matter what I eat. It is definitely worse on an empty stomach and therefore I was very thin to begin with and now I am overweight. Foods like pretzels and carbs soothe it while i'm eating but it comes back right after. I am constantly chewing gum. I also have gall stones and My Hida scan showed a reduction of function but some say operate and others say it won't help. Endoscopies are normal. One GI doctor said gastritis . The nausea accompanies the acid taste. It comes from my stomach, up my esophagus to my mouth
