B12 deficiency from low intake can also mimic pernicious anemia as they both result in anemia from reduced available B12 for red blood cell creation. The condition can run in families and is an autoimmune condition. This type of anemia occurs when your body cannot absorb vitamin B12, which is needed to make healthy red blood cells and to keep the nervous system working properly. Pernicious anemia refers toВ vitamin B12В deficiency caused by autoantibodies that interfere with vitamin B12 absorption by targeting intrinsic factor (IF), gastric parietal cells, or both. Sickle cells also have a shorter life span than normal red blood cells, leading to an overall shortage of red blood cells and, consequently, anemia. Sickle cells are stiff and sticky and tend to block blood flow in the vessels of the limbs and organs, causing pain and raising the risk for infection.

The disorder is caused by a mutation in the gene that tells the body to make hemoglobin, a protein found in red blood cells that binds to oxygen in the lungs and carries it to tissues throughout the body.ДЄs a result of the mutation, the body produces a defective form of hemoglobin called hemoglobin S, which causes red blood cells to sickle, or develop a crescent shape. Sickle cell anemia is an inherited blood disorder characterized by both a deficiency of healthy red blood cells and painful episodes called sickle cell crises. ( 3) In Western countries, the incidence is approximately two per million per year, and estimated to be two- to threefold higher in Asia. While the condition is rare, each year between 600 and 900 people in the United States are diagnosed with aplastic anemia, according to the Aplastic Anemia and MDS International Foundation, although the accuracy of the epidemiological data for the United States is still being determined. Because of this, it is sometimes referred to as bone marrow failure. Not having enough working red blood cells may lead to tiredness and shortness of breath.ДЄplastic anemiaВ is a blood disorder in which the body's bone marrow - the soft tissue in the center of bones - doesn't make enough healthy blood cells. Red blood cells carry oxygen to the body's tissues and remove carbon dioxide. The World Health Organization (WHO) states that this type of anemia, which is the most common and widespread nutritional disorder in the world, largely contributes to the fact that more than 30 percent of the world's population is anemic. Iron-deficiency anemia,В which is the most common type of anemiaВ and occurs when your blood doesn't have enough iron to produce healthy red blood cells and hemoglobin. There are different types of anemia, including, but not limited to: Red blood cells carry oxygen to the body's tissues. The reason for this is that anemia occurs when your body doesn't have adequate healthy red blood cells. The condition is often associated with being tired and weak.

Anemia is a condition that develops when your red blood cell count or hemoglobin is less than normal.
