Hello. I've suffered from GERD for many years. It has gotten to the point where it's irritated my esophagus and I've been diagnosed with esophagitis. I don't like taking medications that suppress stomach acid because we need our stomach acid to help digest food and help prevent infection caused by bad bacteria in the digestive tract. I've gotten two stomach/intestinal infections from using such medications.
That led me to research possible root causes of chronic GERD. I've found that it comes from an unhealthy unbalanced ecosystem in the digestive tract. We need enzymes, a lot of friendly gut bacteria, and a healthy diet to keep the digestive tract in balance. Further research led me to believe that a possible source/cause of an imbalanced digestive ecosystem is root canals and silver dental fillings. Root canals harbor infectious bacteria that can harm many parts of the body and upset the delicate balance of the digestive tract. Silver fillings, well, where do I begin?? They contain mercury, - an extremely toxic/poisonous substance, that gets in to the digestive tract whenever you eat food, drink beverages, brush your teeth, or swallow saliva. The mercury upsets the ecosystem of the digestive tract, destroying the friendly bacteria there. This causes a chain reaction which throws your entire digestive tract off.
Just thought I'd throw this information out there for those who are struggling with trying to find the underlying cause of your GERD. This is just one possibility. It may not be the answer for everybody, but it could help some of you. I am personally going to have all six of my silver fillings removed asap. I know they are a big reason I don't have good digestive health.
