Pernicious anemia and sickle-cell anemia are two anemias.
A medical condition in which the capacity of the blood to transport oxygen to the tissues is reduced, either because of too few red blood cells, or because of too little hemoglobin, resulting in pallor and fatigue
Having fewer than the normal number of red blood cells, causing symptoms of tiredness, shortness of breath and weakness
The condition of having too few red blood cells If the blood is low on red blood cells, the body does not get enough oxygen A low hemoglobin is a sign of anemia See also Epogen
a condition in which the number of red blood cells is less than normal, resulting in less oxygen being carried to the body's cells
Anemia is a condition in which a deficiency in the size or number of erythrocytes (red blood cells) or the amount of hemoglobin they contain limits the exchange of oxygen and carbon dioxide between the blood and the tissue cells Most anemias are caused by a lack of nutrients required for normal erythrocyte synthesis, principally iron, vitamin B-12, and folic acid Others result from a variety of conditions, such as hemorrhage, genetic abnormalities, chronic disease states or drug toxicity
Below normal levels of red blood cells or hemoglobin, or both, which can be caused by many different conditions, including iron deficiency Symptoms may include fatigue, weakness, headache, and dizziness Appropriate blood tests will confirm the diagnosis of anemia and shed light on its etiology
any condition in which there are too few red blood cells, or the red blood cells are immature or too small, or they contain too little hemoglobin
blood disorder caused by a deficiency of red blood cells or hemoglobin (the oxygen-carrying protein in red blood cells)
Having low red blood cell counts Since red blood cells deliver oxygen to the various organs and muscles, anemia produces fatigue, especially with exertion
A condition characterized by a deficiency of red blood cells Anemia reduces the amount of oxygen available to the body
(a-NEE-mee-a): A condition in which the number of red blood cells is below normal
n (a-NEE-mee-uh) Too few red blood cells in the bloodstream, resulting in insufficient oxygen to tissues and organs
Anemia is a condition characterized by oxygen carrying deficiency caused by a low amount of red blood cells, iron deficiency, or sickle cell formation of red blood cells
a blood disorder caused by a deficiency of red blood cells or hemoglobin (the oxygen-carrying protein in red blood cells)
a condition where there is a deficit of red blood cells that are produced by the bone marrow Anemia can also be the result of cancer treatment
condition caused by a reduction in the amount of red blood cells that are produced by the bone marrow; anemia can be a result of the cancer itself or from the treatments; symptoms of anemia include fatigue and dyspnea
Any condition in which the number of red blood cells per mm3, the amount of hemoglobin in 100 ml of blood, and/or the volume of packed red blood cells per 100 ml of blood are less than normal; clinically, generally pertaining to the concentration of oxygen-transporting material in a designated volume of blood Anemia is frequently manifested by pallor of the skin and mucous membranes, shortness of breath, palpitations of the heart, soft systolic murmurs, lethargy, and fatigability
Any condition where the amount of red blood cells and/or hemoglobin is less than normal This can impair the blood's ability to deliver sufficient amounts of oxygen throughout the body
A medical condition in which the capacity of the blood to transport oxygen to the tissues is reduced, either because of too few red blood cells, or because of too little haemoglobin, resulting in pallor and fatigue
genus of terrestrial or lithophytic ferns having pinnatifid fronds; chiefly of tropical America a deficiency of red blood cells a lack of vitality
see anaemia. the usual American spelling of anaemia (anaimia , from haima ). Condition in which erythrocytes are reduced in number or volume or are deficient in hemoglobin. The patient is usually noticeably pale. Close to 100 varieties exist (including aplastic anemia, pernicious anemia, and sickle-cell anemia), distinguished by cause; erythrocyte size, shape, and hemoglobin content; and symptoms. Anemia may result from blood loss; increased destruction, reduced production, or inhibited formation of red cells; or hormone deficiency. Treatment may involve nutrition, toxin removal, drugs, surgery, or transfusion. See also folic-acid-deficiency anemia, iron-deficiency anemia. aplastic anemia anemia of bone marrow failure folic acid deficiency anemia iron deficiency anemia pernicious anemia sickle cell anemia
{i} condition caused by a lack of red blood cells and characterized by weakness and breathlessness (Pathology); weak, powerless, lack of vitality
A reduction in the number of red blood cells Limits the ability of the blood to carry oxygen and other nutrients around the body, and excretion of waste products (such as carbon dioxide) the reduction in the red blood cells results in the starvation of tissues of oxygen and other nutrients Anaemic fish typically show pale gills, due to the reduced number of red blood cells
anaemia anaemias in AM, use anemia Anaemia is a medical condition in which there are too few red cells in your blood, causing you to feel tired and look pale. anemia a medical condition in which there are too few red cells in your blood
Having a low red blood cell count or lack of red blood cells, resulting in weakness and lack of oxygen in the organs Symptoms of anaemia include feeling tired and weak, and shortness of breath
A shortage of red blood cells in the body, causing tiredness, shortage of breath and pale skin One of the functions of the kidneys is to make EPO (erythropoeitin), which stimulates the bone marrow to make blood cells In kidney failure, EPO is not made and anaemia results
A shortage of red blood cells, leading to tiredness and breathlessness Aspiration biopsy A procedure to remove cells from the womb using a long thin plastic tube passed through the vagina Click here for further information
* means less than the normal number of red blood cells Red blood cells are responsible for carrying oxygen If anaemic, a person may feel lethargic, suffer shortness of breath, look pale and feel tired Anaemia may be corrected by blood transfusions
A decrease in the number of red blood cells or the total level of haemoglobin (see below) This makes it harder for the blood to get oxygen to the rest of the body, causing symptoms such as weakness, tiredness or shortness of breath Anaemia in myeloma can be caused by the myeloma cells in the bone marrow interfering with red blood cell production, or as a side effect of chemotherapy
An uncommon disorder characterized by the failure of the bone marrow to produce blood cells It may occur as an inherited condition (see Fanconi's anemia) or, more often, the disease develops later in life This form is called acquired aplastic anemia It leads to a severe shortage of all types of blood cell causing tiredness, susceptibility to infection, and potentially serious problems with bleeding as a result of a deficiency in blood platelets The acquired disease is usually the result of an autoimmune attack of lymphocytes against blood cell progenitors preventing normal blood cell formation
a form of anemia generally unresponsive to antianemia therapy, often accompanied by granulocytopenia or agranulocytosis (decrease in granulocytes) and thrombocytopenia (decrease in thrombocytes), in which the bone marrow may not necessarily be acellular but fails to produce adequate numbers of peripheral blood elements (RBCs, WBCs, and thrombocytes)
one type of anemia that occurs when the bone marrow produces too few of all three types of blood cells: red blood cells, white blood cells, and platelets
A form of anemia in which the capacity of the bone marrow to generate red blood cells is defective. This anemia may be caused by bone marrow disease or exposure to toxic agents, such as radiation, chemicals, or drugs. Also called pancytopenia. or anemia of bone-marrow failure Inadequate blood-cell formation by bone marrow. Pancytopenia is the lack of all blood-cell types (erythrocytes, leukocytes, and platelets), but any combination may be missing. Drug, chemical, or radiation exposure most often causes the disease, but about half of all cases have no known cause. It may occur at any age. Acute disease may be quickly severe, even fatal; chronic disease has symptoms including weakness, shortness of breath, headache, fever, and pounding heart. There is usually a waxy pallor. Hemorrhages occur in mucous membranes, skin, and other organs. Lack of white blood cells lowers resistance to infection and becomes the major cause of death. Very low platelet count may lead to severe bleeding. The treatment of choice is bone-marrow transplantation. Otherwise treatment involves avoiding any known toxic agent and giving fluids, glucose, and proteins (often intravenously) as well as blood components and antibiotics
a fatal form of homozygous thalassemia (inherited from both parents) in which there is no hemoglobin; skeletal deformations; heart and spleen and liver enlarged
Anemia resulting from too little folic acid, needed for red-blood-cell maturation (see erythrocyte). White-cell and platelet levels are also often low. Progressive gastrointestinal problems develop. It may result from poor diet or from malabsorption, cirrhosis of the liver, or anticonvulsant drugs; it may also occur in the last three months of pregnancy and in severe hemolytic anemia (in which red cells break down). The blood profile resembles that of pernicious anemia. Taking folic acid causes rapid improvement; an adequate diet cures cases caused by malnutrition
Most common type of anemia, which may develop in times of high iron loss and depletion of iron stores (e.g., rapid growth, pregnancy, menstruation) or in settings of low dietary iron intake or inefficient iron uptake (e.g., starvation, intestinal parasites, gastrectomy). Much of the world's population is iron-deficient to some degree. Symptoms include low energy level and sometimes paleness, shortness of breath, cold extremities, sore tongue, or dry skin. In advanced cases, red blood cells are small, pale, and low in hemoglobin, blood iron levels are reduced, and body iron stores are depleted. Treatment with iron usually brings quick improvement
a chronic progressive anemia of older adults; thought to result from a lack of intrinsic factor (a substance secreted by the stomach that is responsible for the absorption of vitamin B12)
A severe anemia most often affecting older adults, caused by failure of the stomach to absorb vitamin B and characterized by abnormally large red blood cells, gastrointestinal disturbances, and lesions of the spinal cord. Slow-developing disease in which vitamin B12 (see vitamin B complex) deficiency impairs red-blood-cell production. It can result from a diet lacking in vitamin B12 or when intrinsic factor, a substance needed for intestinal absorption of B12, either is not produced by stomach cells or cannot bind to the vitamin. It causes weakness, waxy pallor, shiny tongue, and stomach, intestinal, and neurological problems. Its slow development can allow anemia to become very severe by the time of diagnosis. Monthly B12 injections into muscle soon reverses the anemia, but the injections must be continued for life
any of various anemic conditions that are not successfully treated by any means other than blood transfusions (and that are not associated with another primary disease)
(Medicine) hereditary disease characterized by anemia resulting from defective hemoglobin production (causes deformed red blood cells, oxygen deficiency, and circulatory problems)
A chronic, usually fatal anemia marked by sickle-shaped red blood cells, occurring almost exclusively in Black people of Africa or of African descent, and characterized by episodic pain in the joints, fever, leg ulcers, and jaundice. The disease occurs in individuals who are homozygous for a mutant hemoglobin gene. Also called sickle cell disease
Blood disorder (see hemoglobinopathy) seen mainly in persons of Sub-Saharan African ancestry and their descendants and in those from the Middle East, the Mediterranean area, and India. About 1 in 400 blacks worldwide has the disease, caused by inheriting two copies of a recessive gene that makes those with one copy (about 1 in 12 blacks worldwide) resistant to malaria. The gene specifies a variant hemoglobin (hemoglobin S or Hb S) that distorts red blood cells (erythrocytes) into a rigid sickle shape. The cells become clogged in capillaries, damaging or destroying various tissues. Symptoms include chronic anemia, shortness of breath, fever, and episodic "crises" (severe pain in the abdomen, bones, or muscles). Hydroxyurea treatment triggers production of fetal hemoglobin (Hb F), which does not sickle, greatly lessening severity of crises and increasing life expectancy, previously about 45 years
