A shortage of haemoglobin (the pigment carrying oxygen in red blood cells). Symptoms include weakness, pale skin, breathlessness, faintness, palpitations, and lowered resistance to infection.

anaemia (pop)

A condition in which the number of red blood cells is below normal.

occurs when the body doesn't have enough red blood cells

(n) a lack of vitality(n) a deficiency of red blood cells

A condition when the level of haemoglobin, the protein in blood which carries oxygen round the body, is lower than normal. It can be mild or severe and can cause tiredness, breathlessness, fainting, h [..]

A reduced number of red blood cells

lack of sufficient red blood cells, sometimes caused by iron deficiency and worsened by the medical practice of bleeding patients for virtually every condition. Also known as green fever, green sickne [..]

Deficiency of red blood cells (19thC)

Too little haemoglobin in the blood (see ‘Haemoglobin’).

Anaemia is a condition where there is a low level of a substance called haemoglobin in the blood. Haemoglobin is responsible for the transport of oxygen around the blood within red blood cells. The mo [..]

a condition in which the oxygen-carrying haemoglobin pigment levels are below normal in the blood. Signs include pale gums and listlessness.

Anaemia occurs when there is a decreased amount of red blood cells, or the amount of haemoglobin in the cells, in the circulatory system. There are many different causes of anaemia in cats including b [..]

A reduced amount of the substance (haemoglobin) in red blood cells that carries oxygen in the blood. Anaemia can cause tiredness and fatigue, breathlessness and paleness.

When the body does not have as many red blood (oxygen carrying) cells as it should.

A condition that is due to a reduced number of red blood cells or reduced amounts of haemoglobin within them. This results in reduced oxygen carrying capacity and reduced aerobic activity in body cells.

<haematology> Too few red blood cells in the bloodstream, resulting in insufficient oxygen to tissues and organs. Origin: Gr. Haima = blood American spelling: anemia (16 Dec 1997)

A form of anaemia in which the bone marrow fails to produce adequate numbers of peripheral blood elements. American spelling: anemia, aplastic (12 Dec 1998)

Better known today as thalassaemia (or as beta thalassaemia or thalassaemia major).The clinical picture of this important type of anaemia was first described in 1925 by the paediatrician Thomas Benton Cooley. Another name for the disease is Mediterranean anaemia. The name thalassaemia was coined by the Nobel Prise winning pathologist George Whipple [..]

A familial disorder characterised by anaemia with multinuclear erythroblasts, karyorrhexis, asynchrony of nuclear and cytoplasmic maturation, and various nuclear abnormalities of bone marrow erythrocyte precursors. Type II is the most common of the 3 types of congenital dyserythropoietic anaemia; it is often referred to as hempas, based on the here [..]

Anaemia due to decreased life span of erythrocytes. American spelling: anemia, hemolytic (12 Dec 1998)

Acquired haemolytic anaemia due to the presence of autoantibodies which agglutinate or lyse the patient's own red cells. American spelling: anemia, hemolytic, autoimmune (12 Dec 1998)

Haemolytic anaemia due to various intrinsic defects of the erythrocyte. American spelling: anemia, hemolytic, congenital (12 Dec 1998)

Any one of a group of congenital haemolytic anaemias in which there is no abnormal haemoglobin or spherocytosis and in which there is a defect of glycolysis in the erythrocyte. In some cases, pyruvate kinase deficiency has been demonstrated; in other cases, glucose-6-phosphate dehydrogenase deficiency has been demonstrated. American spelling: anemi [..]

Anaemia characterised by a decrease in the ratio of the weight of haemoglobin to the volume of the erythrocyte, i.e., the mean corpuscular haemoglobin concentration is less than normal. The individual cells contain less haemoglobin than they could have under optimal conditions. Hypochromic anaemia may be caused by iron deficiency from a low iron in [..]

Deficiency of iron results in anaemia because iron is necessary to make haemoglobin, the key molecule in red blood cells responsible for the transport of oxygen. In iron deficiency anaemia, the red cells are unusally small (microcytic) and pale (hypochromic). Characteristic features of iron deficiency anaemia in children include failure to thrive ( [..]

Anaemia characterised by larger than normal erythrocytes, increased mean corpuscular volume (mcv) and increased mean corpuscular haemoglobin (mch). American spelling: anemia, macrocytic (12 Dec 1998)

Better known today as thalassaemia (or as beta thalassaemia or thalassaemia major).The clinical picture of this important type of anaemia was first described in 1925 by the paediatrician Thomas Benton Cooley. The name thalassaemia was coined by the Nobel Prise winning pathologist George Whipple and the professor of paediatrics Wm Bradford at U. Of [..]

Anaemia characterised by the presence of megaloblasts in the bone marrow. American spelling: anemia, megaloblastic (12 Dec 1998)

Anaemia characterised by appearance of immature myeloid and nucleated erythrocytes in the peripheral blood, resulting from infiltration of the bone marrow by foreign or abnormal tissue. American spelling: anemia, myelophthisic (12 Dec 1998)

The mildest form of erythroblastosis foetalis in which anaemia is the chief manifestation. American spelling: anemia, neonatal (12 Dec 1998)

A megaloblastic anaemia occurring in children but more commonly in later life, characterised by histamine-fast achlorhydria, in which the laboratory and clinical manifestations are based on malabsorption of vitamin B12 due to a failure of the gastric mucosa to secrete adequate and potent intrinsic factor. American spelling: anemia, pernicious (12 D [..]

Anaemia (a shortage of red blood cells) unresponsive to treatment. American spelling: anemia, refractory (12 Dec 1998)

Chronic refractory anaemia with granulocytopenia, and/or thrombocytopenia. Myeloblasts and progranulocytes constitute 5 to 40 percent of the nucleated marrow cells. American spelling: anemia, refractory, with excess of blasts (12 Dec 1998)

A disease characterised by chronic haemolytic anaemia, episodic painful crises, and pathologic involvement of many organs. It is the clinical expression of homozygosity for haemoglobin s. American spelling: anemia, sickle cell (12 Dec 1998)
