Anemia
The
literal meaning of the word
Anemia (also spelled
Anaemia) is
lacking blood or without blood.
People
suffering from the condition known as
Anemia have
a deficiency of
red
blood cells and/or
hemoglobin.
Hemoglobin
is a protein found in red blood cells that carries oxygen
throughout the body.
Anemia
reduces the ability of your blood to transfer oxygen to the
various tissues throughout the body. There are three main
causes of
Anemia.
The causes include the following:
-
Hemorrhage – excessive blood loss.
-
Hemolysis – excessive red blood cell destruction.
-
Deficient red blood cell production
Of all
possible blood disorders,
Anemia is
the most common. There are several kinds of
Anemia.
produced by a variety of underlying causes. Consider the
following Anemia classifications:
-
Decreased Anemia
( Microcytic
Anemia)
-
Normal
Anemia
( Normocytic
Anemia)
-
Enlarged
Anemia
( Macrocytic
Anemia or
Megaloblastic Anemia).
Anemia
goes undetected in many people; however, understanding what
the potential symptoms may be will help people to diagnose
Anemia.
The following is a list of symptoms, which should be reviewed
carefully:
-
Weakness
-
Fatigue
-
Shortness of breath
-
Palpitations
-
Sweatiness
The
most common type of
Anemia is
Iron Deficiency
Anemia.
Iron Deficiency Anemia
is caused when a person’s dietary intake or iron absorption is
insufficient. Iron is a critical part of
hemoglobin.
Thus, low iron level will decrease the quantities of
hemoglobin
in red blood cells causing poor oxygenation of the various
tissues of the body. Much less common causes of
Anemia are
hemoglobinopathies such as
Sickle-Cell Disease
and
Thalassemia.
Anemia
develops for a variety of reasons although many of the causes
are rare in relation to
Iron Deficiency Anemia.
As a result of the variety of
Anemia Causes,
Anemia
is referred to and named using the following distinctions in
addition to the classifications listed above:
-
Sideroblastic Anemia
– caused by abnormal production of red blood cells.
-
Aplastic
Anemia
– caused by the bone marrow’s inability to produce blood
cells.
-
Megaloblastic Anemia
– caused by a deficiency of either vitamin B12 or folic acid
-
Pernicious Anemia
– caused by the inability to absorb vitamin B12 from food.
