Iron-deficiency anemia is anemia caused by a lack of iron. [3] Anemia is defined as a decrease in the number of red blood cells or the amount of hemoglobin in the blood. [3] When onset is slow, symptoms are often vague such as feeling tired, weak, short of breath, or having decreased ability to exercise. [1]
Aplastic anemia [2] (AA) [3] is a severe hematologic condition in which the body fails to make blood cells in sufficient numbers. Blood cells are produced in the bone marrow by stem cells that reside there. [4] Aplastic anemia causes a deficiency of all blood cell types: red blood cells, white blood cells, and platelets. [5] [6]
Cooley noted similarities in symptoms of children in his care having Greek or Italian ancestry; he named it "erythroblastic anemia," but it became popularly known as Cooley's anemia (now termed beta thalassemia major). [117] The term "thalassemia" was coined by George Whipple in 1932. The word "thalassemia" comes from the Greek word thalassa ...
Anemia (also spelled anaemia in British English) is a blood disorder in which the blood has a reduced ability to carry oxygen.This can be due to a lower than normal number of red blood cells, a reduction in the amount of hemoglobin available for oxygen transport, or abnormalities in hemoglobin that impair its function.
Hemolytic anemia affects nonhuman species as well as humans. It has been found, in a number of animal species, to result from specific triggers. [51] Some notable cases include hemolytic anemia found in black rhinos kept in captivity, with the disease, in one instance, affecting 20% of captive rhinos at a specific facility.
Anemia of chronic disease (ACD) [1] [2] or anemia of chronic inflammation [3] is a form of anemia seen in chronic infection, chronic immune activation, and malignancy. These conditions all produce elevation of interleukin-6 , which stimulates hepcidin production and release from the liver.
Megaloblastic anemia is a type of macrocytic anemia. An anemia is a red blood cell defect that can lead to an undersupply of oxygen. [1] Megaloblastic anemia results from inhibition of DNA synthesis during red blood cell production. [2] When DNA synthesis is impaired, the cell cycle cannot progress from the G2 growth stage to the mitosis (M ...
Dacrocytes (teardrop cells) Dacrocytes compared to other forms of poikilocytosis A dacrocyte (or dacryocyte) is a type of poikilocyte that is shaped like a teardrop (a "teardrop cell").
