Pernicious Anemia Vitamin B12
Pernicious anemia is a type of anemia that used to be deadly. Pernicious, means deadly, this type of anemia was deadly due to the lack of available treatment. Nowadays it is very well treated with B12 shots. Anemia is when the body does not have enough healthy red blood cells. Red blood cells are important because they carry oxygen through the whole body.
Pernicious anemia is when there is a decrease in red blood cells due to the intestines not being able to absorb vitamin B12 efficiently. Vitamin B12 is crucial for red blood cell production and function in the body. Pernicious anemia is rare.
Causes of Pernicious Anemia
Pernicious anemia is when your body cannot absorb vitamin B12. This can happen if you have an autoimmune process where you are unable to produce an intrinsic factor in the stomach. Intrinsic factor helps your body to absorb vitamin B12 in the small intestines.
Another cause of Pernicious anemia is weakened stomach lining.
In extremely rare cases Pernicious anemia may be passed along in a family, this is known as congenital Pernicious anemia. In congenital Pernicious anemia babies do not produce enough intrinsic factor.
Having someone in your family with it also raises your risks.
If you have one of these conditions you are also at a higher risk of developing Pernicious anemia; Addison’s disease, Grave’s, hypothyroidism, hypoparathyroidism, myasthenia gravis, type 1 diabetes, testicular dysfunction, or celiac disease.

A person on a vegetarian diet can also be at higher risk of Pernicious anemia because of the lack of foods with vitamin B12.
