A decrease in red blood cells that occurs when the body cannot absorb vitamin b12
A megaloblastic anemia occurring in children but more commonly in later life, characterized by histamine-fast achlorhydria, in which the laboratory and clinical manifestations are based on malabsorption of vitamin b 12 due to a failure of the gastric mucosa to secrete adequate and potent intrinsic factor. (Dorland, 27th ed)
A type of anemia (low red blood cell count) caused by the body's inability to absorb vitamin b12.
Anemia due to poor intestinal absorption of vitamin b12 caused by defective production of intrinsic factor (a carrier protein) by the gastric mucosa.
Megaloblastic anemia caused by vitamin b-12 deficiency due to impaired absorption. The impaired absorption of vitamin b-12 is secondary to atrophic gastritis and loss of gastric parietal cells.
