Welcome to the forum!!!
As people mentioned before, heartburn is not just about the acid stomach.
What is the exact diagnosis?
What tests were done to diagnose?
What have you tried except atiacid and diet?
Do you feel hungry after your eat?
What are your stress levels?
Have you try alternative medicine?
do you have stomach ache? (what side of the stomach hurt more?)
For how long you have this problem?
Heartburn is just a little inconvenience, a sign that something is going wrong.... what is important that is going on inside!
I hope you all agree that the goal is not to get rid of Heartburn.....but much more complicated.
Atiacid drugs allow all kind of bacteria to enter digestive system. Stomach acid suppose to kill them. In addition in the low acid environment the stomach is not able to prepare the food for further digestion. Hence - waste of food and malnutrition. Moreover, by suppressing production of the acid, you make your stomach produce more acid....and so on....
Speaking of surgery.... since anti-reflux surgery just reinforces the "valve" between the esophagus and the stomach... but ACIDITY LEVELS ARE still high... (only of the acidity and other digestive function are normal - this surgery makes sense. otherwise it is like....mmm...putting a tight lid on the boiling pot...)
And this boiling pot will continue to produce acid....and ruin duodenum...etc....
This problem ( just as many others) requires holistic approach...holistic approach requires some time, effort and persistence... make take months....or longer, depends how bad is the condition.
I have "hight acid", "gerd", "reflux" and whatever my doctor calls is, and I successfully cope with it for many years without drugs. maybe can share some useful hints with you.
