Heaviness In Stomach After Eating, Burping, Acid Reflux, Unformed Stools, No Feeling Of Completion After Passing Stools. All Tests Normal. No Help From Pantacid, Darolac Etc. Help

Hello Doctor,

I am from India, and I suffer this digestion related problem for many years now. After taking my meals I get a feeling of heavy stomach and fullness(even if I had taken a small meal), When I drink water even after an hour or so after meals I get burping and sour water comes back to my mouth, the motion is not formed or at times I get hard and there is a feeling of not complete evacuation. Have consulted many doctors who have prescribed many tests including Ultrasound of stomach & abdomen, Blood Test for Celiac disease but it has been normal. They have presccribed me medicines like: Pantocid, Darolac, Unienzyme etc. I have felt a little better with these meddicines but the condition relapses after the medical course is over. Plz. suggest.
