What was done

This narrative review synthesizes the physiological roles of gastric acid, details the downstream consequences of hypochlorhydria and achlorhydria in autoimmune gastritis (AIG), and outlines a theoretical rationale for therapeutic gastric re-acidification.

What was found

The abstract reports no empirical trial data, quantitative metrics, or comparative clinical outcomes. It outlines the rationale that betaine hydrochloride (BHCL) could alleviate gastrointestinal symptoms and theoretically reduce hypergastrinemia and N-nitroso compound formation, while supplemental vitamin C could independently limit N-nitroso synthesis.

Why it matters

Patients with autoimmune gastritis frequently experience acid loss and are sometimes inappropriately prescribed acid-suppressing medications; this framework introduces re-acidification as a prospective therapeutic strategy requiring clinical validation.

Limits

This is an unstructured narrative review providing theoretical and mechanistic proposals rather than empirical or clinical trial evidence. No human trials, dosing protocols, safety endpoints, or efficacy data for betaine hydrochloride in autoimmune gastritis are presented.
