malignant anaemia

[LeeTot 0]

a chronic progressive anemia of older adults; thought to result from a lack of intrinsic factor (a substance secreted by the stomach that is responsible for the absorption of vitamin B12)

[Tanya Shivari]

Malignant anemia, also referred to as pernicious anemia, is a blood disorder characterized by the bodys inability to absorb sufficient amounts of vitamin B12 from the gastrointestinal tract, leading to insufficient red blood cell production. As vitamin B12 is essential for the production of red blood cells, this deficient absorption affects the size and number of red blood cells, resulting in symptoms like fatigue, dizziness, pallor, and sometimes serious neurological damage.
