        <p>Blood is actually a liquid made up of several different cell
types. One of the most important and most numerous cell types is the red
blood cell. The purpose of the red blood cell is to deliver oxygen to the
body. Anemia describes the condition in which the number of red blood
cells in your blood is low. For this reason, doctors sometimes describe
someone with anemia as having a low blood count. A person who has anemia
is called anemic.<br><br>Anemia is a condition where there is a lower
than normal number of red blood cells in the blood, usually measured by a
decrease in the amount of hemoglobin. Hemoglobin is the oxygen-carrying
part of red blood cells. It gives these blood cells their red
color.<br><br>A person with anemia will feel tired and weak because the
body's tissues are being starved of oxygen. In fact, fatigue is the main
symptom of most types of anemia. The severity of symptoms is in part
related to the severity of anemia. Mild anemia can occur without symptoms
and may be detected only during a medical exam that includes a blood
test.<br><br>Anemia Symptoms<br><br>Other signs and symptoms of anemia
include:<br><br>•   Shortness of breath<br>•  Â
Dizziness<br>•   Headache<br>•   Coldness in the hands and
feet<br>•   Pale skin<br>•   Chest pain<br><br>Anemia
Causes<br><br>Anemia is caused by a deficiency of Hemoglobin. Hemoglobin
is a pigment made up of protein and iron. Hemoglobin’s main job is to
pick up oxygen from the lungs and deposit into the red blood cells, which
in turn carries the oxygen throughout the body. Without Protein and Iron
you have a loss of Hemoglobin, which means you have a lost of oxygen for
the red blood cells.<br><br>Insufficient iron in the diet is the most
common cause of anemia worldwide. There tends to be a lack of vitamin B12
and folic acid in the diet as well. These deficiencies are less common in
North America, but still do occur. People likely to have dietary iron-
deficiency anemia are infants, pregnant women, and teenagers going
through a growth spurt. Slow bleeding can also cause iron-deficiency
anemia.<br><br>Types of Anemia<br><br>Some types of anemia occur because
the body cannot make enough hemoglobin, as is the case with iron
deficiency anemia and pernicious anemia. Other types of anemia occur when
the body makes sufficient hemoglobin, but it doesn't function
properly.<br><br>Iron Deficiency Anemia<br><br>The body needs iron to
produce the hemoglobin necessary for red blood cell production. In
general, most people need just 1 milligram of iron daily. Menstruating
women need double that dose. <br><br>Pernicious Anemia<br><br>Anemia due
to deficiency of Vitamin B12, known as Pernicious Anemia This is less
common, generally affects people over 40 and results due to Vitamin B12
deficiency.<br><br>Sickle cell anemia<br><br>Sickle cell anemia is a
serious blood disorder and is characterized by the red blood cells taking
a crescent – or sickle – shape. It is a hereditary chronic condition.
It is caused by the presence of an abnormal type of hemoglobin in the red
blood cells and is passed via genetic factors from parents to
children.</p>        <!--INFOLINKS_OFF-->
