hemolytic anemia Hemolytic anemia is a disorder in which the red blood cells are destroyed faster than the bone marrow can produce them.The term for destruction of red blood cells is hemolysis. There are two types of hemolytic anemia, intrinsic and extrinsic:he destruction of the red blood cells is due to a defect within the red blood cells themselves. Intrinsic hemolytic anemias are often inherited, such as sickle cell anemia and thalassemia. These conditions produce red blood cells that do not live as long as normal red blood cells.

Aplastic anemia From Wikipedia, the free encyclopedia. Aplastic anemia (AA) is a disease in which the bone marrow, and the blood stem cells that reside there, are damaged. This causes a deficiency of all three blood cell types (pancytopenia): red blood cells (anemia), white blood cells (leukopenia), and platelets (thrombocytopenia). Aplastic refers to inability of the stem cells to generate the mature blood cells.

Iron-refractory iron deficiency anemia In people with this form of anemia, red blood cells are abnormally small (microcytic) and pale (hypochromic). The symptoms of iron-refractory iron deficiency anemia can include tiredness (fatigue), weakness, pale skin, and other complications.ron-refractory iron deficiency anemia is one of many types of anemia, which is a group of conditions characterized by a shortage of healthy red blood cells.

Anemia, Megaloblastic Pernicious anemia is a rare blood disorder characterized by the inability of the body to properly utilize vitamin B12, which is essential for the development of red blood cells. Most cases result from the lack of the gastric protein known as intrinsic factor, without which vitamin B12 cannot be absorbed.

pernicious anemia Definition. Pernicious anemia is a disease in which the red blood cells are abnormally formed, due to an inability to absorb vitamin B 12. True pernicious anemia refers specifically to a disorder of atrophied parietal cells leading to absent intrinsic factor, resulting in an inability to absorb B 12.s noted, true pernicious anemia refers specifically to a disorder of atrophied parietal cells leading to absent intrinsic factor, resulting in an inability to absorb B 12. However, there are other related conditions that result in decreased absorption of B 12.

Aplastic anemia Aplastic anemia is a rare disease in which the bone marrow and the hematopoietic stem cells that reside there are damaged. This causes a deficiency of all three blood cell types (pancytopenia): red blood cells (anemia), white blood cells (leukopenia), and platelets (thrombocytopenia). Aplastic refers to inability of the stem cells to generate mature blood cells. It is most prevalent in people in their teens and twenties, but is also common among the elderly. It can be caused by exposure to chemicals, drugs, radiation, immune disease, and heredity. However, in about half the cases, the cause is unknown. The definitive diagnosis is by bone marrow biopsy; normal bone marrow has 30–70% blood stem cells, but in aplastic anemia, these cells are mostly gone and replaced by fat.

Hypochromic anemia Hypochromic anemia is a generic term for any type of anemia in which the red blood cells (erythrocytes) are paler than normal. (Hypo-refers to less, and chromic means color .) A normal red blood cell will have an area of pallor in the center of it; it is biconcave disk shaped. In hypochromic cells, this area of central pallor is increased.

Anemia Anemia - Practice Essentials. 1  Anemia is strictly defined as a decrease in red blood cell (RBC) mass. 2  Anemia, like a fever, is a sign that requires investigation to determine the underlying etiology. 3  Methods for measuring RBC mass are time consuming and expensive and usually require transfusion of radiolabeled erythrocytes.

- Anemia (uh-NEE-me-uh) is a condition in which your blood has a lower than normal number of red blood cells. Anemia also can occur if your red blood cells don't contain enough hemoglobin (HEE-muh-glow-bin). Hemoglobin is an iron-rich protein that gives blood its red color. This protein helps red blood cells carry oxygen from the lungs to the rest of the body. If you have anemia, your body doesn't get enough oxygen-rich blood. As a result, you may feel tired or weak.
