Vitamin B12 deficiency anaemia associated with total gastrectomy – http://id.who.int/icd/entity/1965715576
The absence of gastric acid and pepsin in these disorders results in impaired liberation of vitamin B12 (cobalamin) from its binding to food proteins, while the absence of intrinsic factor prevents the normal absorption of food cobalamin.
