“…In these conditions little iron may be absorbed after the oral administration of a ferrous preparation or of 5 g F~ (Badenoch and Callender, 1954), despite the fact that the patients may be iron-deficient. Cartwright and Wintrobc (1952), Crawley (1952) and Thedering and Beck (1953) believe that defective absorption may be responsible for cases of iron-deficiency anaemia in the absence of steatorrhoea or gastric resection. Possibly such patients find it difficult to absorb iron from the food, or metallic iron or ferric iron compounds.…”
