What is pernicious anaemia?
'Pernicious' means having a harmful affect, often in a gradual or subtle way, and anaemia means a low level of red blood cells. However the name pernicious anaemia is used for a specific condition where the body is unable to absorb enough vitamin B12 into the body from the gastro-intestinal tract.
A lack of vitamin B12 causes the condition, but once this form of
anaemia is diagnosed, it can be treated effectively.
