Has it been proven you overproduce acid? High acid is rarely the cause of GERD.
My mother is free of severe GERD and severe LPR. And when i say severe, standing up with burning acid pouring out of her mouth severe. Doctors all told her she had high stomach acid. Incorrect treatment of tagament for 20 years, then nexium for 5 years along with bucketfuls of gaviscon...this treatment was almost fatal.
Today she takes digestive enzyme supplements - helps digest food and prevent acid reflux, betaine HCI with pepsin supplements - increases stomach acid, corrected her numerous deficiencies - neuralizing stomach acid with acid blockers causes nutrient deficiencies - some of those deficiencies cause acid reflux eg: magnesium deficiency - and voila...goodbye GERD, goodbye LPR...oh and goodbye to 25 years of gastritis!
The baking soda (sodium bicarbonate, not baking powder) test...
The following steps help to determine your stomach's acidity:
1. Perform this test first thing in the morning on an empty stomach (before
eating or drinking)
2. Dissolve ¼ teaspoon of baking soda into an 8 oz glass of cold water
3. Drink the solution and start timing
4. Record the time until you first burp up gas
5. Perform this test for 5 consecutive days (or longer) at the same time each day to give a better estimation of your stomach’s acidity
Time until first burp:
If you burp immediately and excessively your stomach acid level is probably too high
Under 2 min: indicates normal acidity
2 - 5 min: low normal acidity
Over 5 min: possible hypochlorhydria (low stomach acid)
No burping indicates possible achlorhydria (no stomach acid).
You may not have an acid problem at all, maybe you have a problem swallowing. If acid is backing up, in my opinion, you will know it quickly, as it will affect your vocal chords and certainly your teeth in a very, very short period of time.
An Endoscopy will determine if acid is indeed backing up. I'd also ask that you have a test to determine if your swallowing reflex is working correctly.
Keep us informed.
I am curious- what other symptoms were present?
