Pernicious anemia is a type of vitamin B12 deficiency anemia (low red blood cells count). Pernicious anemia is most common in Caucasians of northern European ancestry.
Signs and symptoms of pernicious anemia can include
- a tingling sensation of pins and needles in the hands and feet,
- shortness of breath, and
- a bright red, smooth tongue.
Cause of pernicious anemia
Impaired uptake of vitamin B12 due to the lack of a substance known as intrinsic factor (IF) produced by the stomach lining causes pernicious anemia. Doctors believe that the loss of specialized cells in the stomach that produce IF causes the condition. It has been suggested that an autoimmune reaction occurs in the body against these cells that destroys them.
