"Microcytic anemia Microcytic anaemia is any of several types of anaemia characterized by small red blood cells (called microcytes). The normal mean corpuscular volume (abbreviated to MCV on full blood count results) is 80-100 fL, with smaller cells (<80 fL) described as microcytic and larger cells (>100 fL) as macrocytic (the latter occur in macrocytic anemia).The MCV is the average red blood cell size. In microcytic anaemia, the red blood cells (erythrocytes) are usually also hypochromic, meaning that the red blood cells appear paler than usual. This is reflected by a lower-than-normal mean corpuscular hemoglobin concentration (MCHC), a measure representing"

The name is derived from """", meaning ""lack of blood"", from ἀν- ""an-"", ""not"" and αἷμα ""haima"", ""blood"". Anemia goes undetected in many people and symptoms can be minor. The symptoms can be related to an underlying cause or the anemia itself. Most commonly, people with anemia report feelings of weakness or fatigue, and sometimes poor concentration. They may also report shortness of breath on exertion. In very severe anemia, the body may compensate"
"Anemia Anemia is a decrease in the total amount of red blood cells (RBCs) or hemoglobin in the blood, or a lowered ability of the blood to carry oxygen. When anemia comes on slowly, the symptoms are often vague and may include feeling tired, weakness, shortness of breath or a poor ability to exercise. Anemia that comes on quickly often has greater symptoms, which may include confusion, feeling like one is going to pass out, loss of consciousness, or increased thirst. Anemia must be significant before a person becomes noticeably pale. Additional symptoms may occur depending on the underlying cause."
"anemias. These are generally featuring jaundice and elevated lactate dehydrogenase levels. The roots of the words ""anemia"" and ""ischemia"" both refer to the basic idea of ""lack of blood"", but anemia and ischemia are not the same thing in modern medical terminology. The word ""anemia"" used alone implies widespread ""effects"" from blood that either is too scarce (e.g., blood loss) or is dysfunctional in its oxygen-supplying ability (due to whatever type of hemoglobin or erythrocyte problem). In contrast, the word ""ischemia"" refers solely to the lack of blood (poor perfusion). Thus ischemia in a body part can cause localized anemic"
"Anemia is a condition in which an individual does not have enough healthy red blood cells. This will consequently lead to reduced oxygen flow to the body's organs. Most commonly, this is caused by not consuming enough iron. Anemia is used as a marker for overall micronutrient deficiency. Symptoms usually involve overall fatigue and tiredness, as a result of reduced oxygen flow. There are various treatments for anemia, including iron supplements and vitamin B supplements. Blood transfusions may also be used if blood production is low. According to the CDC, “an evaluation of anemia prevalence in the Zaatari refugee camp"
"Asemia Asemia is the term for the medical condition of being unable to understand or express any signs or symbols. It is a more severe condition than aphasia, which is the inability to understand linguistic signs. Asemia is caused by damage to the areas of the brain that process communication – more specifically, when there is damage to the left side of the brain in the areas that process communication such as Broca's and Wernicke's areas. Damage can be inflicted by physical trauma to the brain, but is more commonly caused by stroke and sometimes tumors. The onset of this"

Pyaemia Pyaemia (or pyemia) is a type of septicaemia that leads to widespread abscesses of a metastatic nature. It is usually caused by the staphylococcus bacteria by pus-forming organisms in the blood. Apart from the distinctive abscesses, pyaemia exhibits the same symptoms as other forms of septicaemia. It was almost universally fatal before the introduction of antibiotics. Sir William Osler included a three-page discussion of pyaemia in his textbook ""The Principles and Practice of Medicine"", published in 1892. He defined pyaemia"

The anemia is also classified by severity into mild (110 g/L to normal), moderate (80 g/L to 110 g/L), and severe anemia (less than 80 g/L) in adult males and adult non pregnant females. Different values are used in pregnancy and children. Anemia is typically diagnosed on a complete blood count. Apart from reporting the number of red blood cells and the hemoglobin level, the automatic counters also measure the size of the red blood cells by"
"Greenwood. Mackay discovered that iron deficiency had a very important role in the cause of anemia in infants. She further discovered that breastfed infants had a lower chance of becoming anemic than those fed with artificial milk. Her research also provided compelling evidence that showed infants who were given iron developed fewer infections, gained more weight, and were overall healthier. The findings of her studies were summarized in “Nutritional Anaemia in Infancy” and published in 1931. Helen Mackay was the first person to try to define anemia by defining the lower limit of normal hemoglobin concentration. Today, the World Health"
"Hyperaemia Hyperemia, hyperæmia, or hyperaemia (Greek ὑπέρ (hupér, ""over"") + αἷμα (haîma, “blood”)) is the increase of blood flow to different tissues in the body. It can have medical implications but is also a regulatory response, allowing change in blood supply to different tissues through vasodilation. Clinically, hyperaemia in tissues manifest as erythema (redness of the skin) because of the engorgement of vessels with oxygenated blood. Hyperaemia can also occur due to a fall in atmospheric pressure outside the body. Functional hyperaemia is an increase in blood flow to a tissue due to the presence of metabolites and a change"
"generally expressed as blood hemoglobin concentration (Hb). As anemia develops, there is even more of a significant reduction in the concentration of hemoglobin. Normally this stimulates a significant increased production of erythropoietin (EPO), but this response is diminished in premature infants. Dear, Gill, Newell, Richards and Schwarz (2005) conducted a study to show that there is a weak negative correlation between EPO and Hb. The researchers recruited 39 preterm infants from 10 days of age or as soon as they could manage without respiratory support. They estimated total EPO and Hb weekly and 2 days after a blood transfusion. The"
"Hypochromic anemia Hypochromic anemia, or Hypochromic anaemia, 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. This decrease in redness is due to a disproportionate reduction of red cell hemoglobin (the pigment that imparts the red color) in proportion to the volume of the cell. Clinically the color can be"

"poorer populations only have access to limited diagnostic facilities together with blood transfusions. In some developing countries, there are virtually no facilities for diagnosis or management of thalassemia. The word ""thalassemia"" () derives from the Greek "" thalassa"" (θάλασσα), ""sea"", and New Latin ""-emia"" (from Greek ""haema"" (αἷμα), ""blood""). It was coined because the condition called ""Mediterranean anemia"" was first described in people of Mediterranean ethnicities.

The mechanisms involved are multifactorial and not limited to malabsorption but mainly related to chronic intestinal inflammation, which causes dysregulation of hepcidin that leads to decreased access of iron to the circulation. There are a number of definitions of anemia; reviews provide comparison and contrast of them. A strict but broad definition is an absolute decrease in red blood cell mass, however, a broader definition is a lowered ability of the blood to carry oxygen. An operational definition is a"

The first clear description was by Thomas Addison in 1849. The term ""pernicious"" means ""deadly"", and was used as before the availability of treatment the disease was often fatal. The symptoms of pernicious anemia come on slowly. Untreated, it can lead to neurological complications, and in serious cases, death. Many of the signs and symptoms are due to anemia itself, when anemia is present. Symptoms may consist of the triad"
"Anemia of chronic disease Anemia of chronic disease, or anemia of chronic inflammation, is a form of anemia seen in chronic infection, chronic immune activation, and malignancy. These conditions all produce massive elevation of Interleukin-6, which stimulates hepcidin production and release from the liver, which in turn reduces the iron carrier protein ferroportin so that access of iron to the circulation is reduced. Other mechanisms may also play a role, such as reduced erythropoiesis. Anemia of chronic inflammation is the preferred term since not all chronic diseases are associated with this form of anemia. Anemia is considered when RBCs count"

In addition, anemic patients may experience difficulties with memory and concentration, fatigue, lightheadedness, sensitivity to temperature, low energy levels, shortness of breath, and pale skin. Symptoms of severe or rapid-onset anemia are very dangerous as the body is unable to adjust to the lack of hemoglobin. This may result in shock and death. Mild and moderate anemia have symptoms that develop slowly over time.[5] If patients believe that they are at risk for"

"Aplastic anemia Aplastic anaemia 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 the inability of stem cells to generate mature blood cells. It is more frequent in people in their teens and twenties, but is also common among the elderly. It can be caused by heredity, immune disease, or exposure to chemicals, drugs, or radiation. However, in about half the cases, the cause is"
"anemia are ""hypochromic"" (lacking the red hemoglobin pigment) and ""microcytic"" (smaller than normal). Other anemias are rarer. In hemolysis (accelerated breakdown of red blood cells), associated jaundice is caused by the hemoglobin metabolite bilirubin, and the circulating hemoglobin can cause renal failure. Some mutations in the globin chain are associated with the hemoglobinopathies, such as sickle-cell disease and thalassemia. Other mutations, as discussed at the beginning of the article, are benign and are referred to merely as hemoglobin variants. There is a group of genetic disorders, known as the ""porphyrias"" that are characterized by errors in metabolic pathways of heme"
"Nutritional anemia Nutritional anemia refers to the low concentration of hemoglobin due to poor diet. According to the World Health Organization, a hemoglobin concentration below 7.5 mmol/L and 8. mmol/L for women and men, respectively, is considered to be anemic. Thus, anemia can be diagnosed with blood tests. Hemoglobin is used to transport and deliver oxygen in the body. Without oxygen, the human body cannot undergo respiration and create ATP, thereby depriving cells of energy. Nutritional anemia is caused by a lack of iron, protein, B12, and other vitamins and minerals that needed for the formation of hemoglobin. Folic acid"
"anemia, they are often vague, which may limit their contribution to determining the diagnosis. Anemia is often discovered by routine blood tests. A sufficiently low hemoglobin (Hb) by definition makes the diagnosis of anemia, and a low hematocrit value is also characteristic of anemia. Further studies will be undertaken to determine the anemia's cause. If the anemia is due to iron deficiency, one of the first abnormal values to be noted on a CBC, as the body's iron stores begin to be depleted, will be a high red blood cell distribution width (RDW), reflecting an increased variability in the size"
