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.
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]
Before iron deficiency anemia sets in, “the body will do everything it can to retain the right number of red blood cells. So, it will deplete the storage iron before it depletes the red blood ...
An anemia is a decrease in number of red blood cells (RBCs) or less than the normal quantity of hemoglobin in the blood. [2] [3] However, it can include decreased oxygen-binding ability of each hemoglobin molecule due to deformity or lack in numerical development as in some other types of hemoglobin deficiency.
The normal mean corpuscular volume (abbreviated to MCV on full blood count results, and also known as mean cell volume) is approximately 80–100 fL. When the MCV is <80 fL, the red cells are described as microcytic and when >100 fL, macrocytic (the latter occurs in macrocytic anemia). The MCV is the average red blood cell size.
Often there is mild to severe anemia (low red blood cells or hemoglobin) as thalassemia can affect the production of red blood cells and also affect how long the red blood cells live. [1] Symptoms include tiredness, pallor, bone problems, an enlarged spleen, jaundice, pulmonary hypertension, and dark urine. [1]
Signs and symptoms may include fever, small areas of bleeding into the skin, heart murmur, feeling tired, and low red blood cell count. [ 1 ] [ 8 ] Complications may include backward blood flow in the heart , heart failure – the heart struggling to pump a sufficient amount of blood to meet the body's needs, abnormal electrical conduction in ...
Anemia – a reduction of the red blood cells in the body. Leukopenia – a deficiency of white blood cells, or leukocytes [1] Neutropenia – a type of leukopenia, with a specific deficiency in neutrophils [2] Thrombocytopenia – a deficiency of platelets
