Deficiency of vitamin B12 in vegetarian people
This vitamin is necessary for our body and its functions, if we generate a nutritional deficiency in our body, it can provoke very negative avoidable consequences to our health.
By not providing for a long time vitamin B12, the central nervous system can be affected (confusion, loss of balance, depression or dementia), the heart, the immune system and other threats such as tingling in the extremities of the body, problems in the formation and maturation of red blood cells and DNA.
Anemia of vitamin B12 deficiency
Vitamin B12 requires an intrinsic factor (a protein secreted by the stomach) to be absorbed. If there is a deficit of its absorption caused by a gastric involvement (usually 90% of cases is autoimmune), it can cause a decrease in the manufacture of intrinsic factor and vitamin B12 is not properly absorbed even when ingested in the necessary amounts. This malabsorption leads to a type of anemia called pernicious anemia.
Pernicious anemia is another type of megaloblastic anemia. It does not appear as a result of a deficit intake of vitamin B12, but the deficit is produced because an autoimmune disorder.
In contrast, megaloblastic anemia is caused by shortage of intake or absorption of two different vitamins, vitamin B9 or folic acid and / or vitamin B12, either one, the other or both.
Another type of anemia, macrocytic normochromic anemia,can be caused by a deficiency of vitamin B12, due to the combined action of abuse of alcohol intake.
In any case, when you see one of these types of anemias, it means that the health of red blood cells of our blood is being affected negatively and the transport of oxygen, to all the tissues and cells of our body is not performed properly.
