Achlorhydria

Adding acid back into the stomach resolves GERD, heartburn, and acid reflux in many cases. Achlorhydria is a condition in which the stomach produces no acid; hypochlorhydria refers to diminished acid production. Hypothyroidism impairs the body's ability to produce stomach acid. H. pylori infection directly depletes stomach acid, making the gastric environment less acidic. Apple cider vinegar and betaine hydrochloride are two approaches to restoring stomach acid.
