What is pernicious anemea?

Answer 1

This is anaemia (lowered blood haemoglobin) due to a lack of vitamin B12 absorbed from the intestinal tract, due to a lack of intrinsic factor usually. This can be due to auto antibodies against the cells that produce intrinsic factor, stomach ulcers crowding out the cells that produce intrinsic factor, a hereditary lack of intrinsic factor or the after effects of surgery, illness or fish tapeworm. This gives a macrocytic anaemia. Pernicious anemia is an autoimmune disease that renders the person unable to absorb sufficient Vitamin B-12. Eventually the person becomes Vitamin B-12 deficient and must be treated. Prior to the availability of treatment persons died from the disease, hence the name pernicious. It is critical that treatment be obtained as soon as possible. You can find more information at the following website: www.pernicious-anaemia-society.org

Answer 2

Pernicius Anemia is when your body is unable to absorb the Vitiman B12, which is what your body needs to produce red blood cells. And if you can't produce these blood cells then you aren't getting the Oxygen you need.

Answer 3

Pernicious Anemia is when the body is unable to absorb the Vitiman B12, meaning your body cannot manifest enough red blood cells for the amount of Oxygen your body needs.

Answer 4

it is an autoimmune desease that renders a person unable to absorb iron

Answer 5

True pernicious anemia refers specifically to a disorder of atrophied parietal cells leading to absent intrinsic factor, resulting in an inability to absorb B12
