achlorhydria

Absence of the normal hydrochloric acid in the stomach as a result of wasting (atrophy) of the acid-secreting cells in the lining. Achlorhydria is commonly found in PERNICIOUS ANAEMIA when autoimmune damage to the stomach lining is associated with loss of secretion of an intrinsic factor in the stomach that leads to failure of vitamin B12 absorption.
