‘’Reasons of
Anemia’’
Ultimately,
only three causes of anemia exist:
Blood loss,
Increased
destruction of RBCs (hemolysis), and
Decreased making
of RBCs.
Each of
these reasons includes a number of disorders that need specific and appropriate
therapy.: ‘’Reasons of
Anemia’’
Vitamin deficiency Anemia.
In addition
to iron, body requirements foliate and vitamin B-12 to produce enough healthy
red blood cells. A diet lacking in these and other key nutrients can reason decreased
red blood cell production.
Certain people
may consume enough B-12, but their bodies lack a substance called ‘Intrinsic
factor’ vital for the proper absorption of the vitamin. This can lead to
vitamin deficiency anemia, also recognized as pernicious anemia. ‘’Reasons of
Anemia’’
Iron deficiency anemia.
This is the
most common kind of anemia worldwide.
Affected by
a shortage of iron in body. Bone marrow needs iron to make hemoglobin. Without
adequate iron, body can’t produce sufficient hemoglobin for red blood cells.
This kind of
anemia occurs in many pregnant women. ‘’Reasons of
Anemia’’
It is also
caused by blood loss, such as from heavy menstrual bleeding, an ulcer, cancer
and regular usage of some pain killers, especially aspirin.
Anemia due to blood loss
It can be of
rapid onset like in cases of trauma and bleeding or slow ongoing procedure like
bleeding from the gut due to peptic ulcers or inflammatory bowel diseases like
crohn’s disease ‘’Reasons of
Anemia’’
Anemia of chronic disease.
Certain long
standing diseases like cancer, HIV/AIDS, rheumatoid arthritis, kidney disease,
Crohn’s disease and other chronic inflammatory diseases, can interfere with the
making of red blood cells.
Aplastic anemia
This rare,
life-threatening anemia occurs when the bone marrow doesn’t create red blood
cells ‘’Reasons of
Anemia’’
Reasons of
aplastic anemia include infections, certain medicines, autoimmune diseases and
exposure to toxic chemicals.
Anemia’s associated with bone marrow
disease.
A variety of
diseases, such as leukemia and myelofibrosis, can reason anemia by affecting
blood production in the bone marrow. Some of these disorders can be life
threatening
Hemolytic anemias.
This group
of anemia’s develops when red blood cells are damaged faster than bone marrow
can replace them. Certain blood diseases increase red blood cell destruction. A
hemolytic anemia can be hereditary, or acquired later in life. ‘’Reasons of
Anemia’’
Sickle cell anemia
This
inherited and occasionally serious condition is an inherited hemolytic anemia.
It’s caused
by a defective form of hemoglobin that forces red blood cells to shoulder an
abnormal crescent (sickle) shape. These irregular blood cells die prematurely, subsequent
in a long term shortage of red blood cells.
Thalassemia
It is
another kind of inherited anemia due to mutation in genes responsible for
globin protein formation leading to abnormal globin protein in the hemoglobin
molecule.
‘’Reasons of
Anemia’’
It is of two
kinds – Alpha Thalassemia and Beta Thalassemia with outcome varying from no indications
to death in infancy depending on the subtype
Anemia’s due to various infections
Viral –
Viral Hepatitis, infective mononucleosis, cytomegalovirus (CMV)
Bacterial –
Clostridial infective (Tetanus), gram-negative bacterial septicemia
Protozoal –
Malaria, leishmaniasis (Kala azar), toxoplasmosis
Anemia due to Drugs or chemicals
They
commonly source the aplastic and hypo plastic group of disorders.
Medicines
like Chloramphenicol (Antibiotic earlier used in Typhoid), sulfonamides or ant
thyroid drugs can source bone marrow suppression and anemia
‘’Reasons of
Anemia’’
Any human
exposed to a adequate dose of inorganic arsenic, benzene, radiation, or the
usual cancer chemotherapy drugs can grow bone marrow depression with anemia.
