How did it continue for you ?Hypochloridia or worse, no acid can cause so many issues that many on this forum complain about.
As someone earlier pointed out, stomach acid decreases with age. This affects nutrient absorption as you all know.
But low acid can also cause dumping syndrome,when the food is not broken down and gets to the small intestine.
Huge blood sugar disregulation, IBS and IBD, bloating, tachycardia, SIBO, and too much serotonin from irritation of the intestinal lining . Followed by leakiness , allergic reactions and endotoxin issues.
The issues that stem from low acid could account for most complaints people have.
While thyroid and sugar ala RP are great, if the body does not have the required elements via poor digestion it becomes a chicken or the egg issue.
I suffer from post prandial tachycardia. Eat or drink and about 30-60 minutes later I have a heart rate of about 130,that stays elevated for about 2 + hours. Magnesium, potassium, t3/T4 at night,increased sugar and salt etc had no effect.
But i noticed that about 6 betaine hcl with meals seemed to keep the heart in a more manageable rate. Glycine doesnt do much for me, imho because I am not digesting it. If I am not digesting it, I doubt I get any of the benefits of it.
