Anemia In Adolescents
To understand what is anemia one should begin with
breathing. The oxygen that is inhaled simply doesnt stop in
lungs. It circulates though out the body and fuels the brains
also. Oxygen travels to all parts of the body though
bloodstream and to be precise in the RBCs I.e. red blood cells.
Now, these RBCs are produced in the bone marrow of the body and
they serve as boats carrying oxygen in the bloodstream. RBCs
have something called hemoglobin, a protein which holds oxygen.
To make adequate hemoglobin body requires iron in plenty. The
iron is supplied by the foods that we take along with other
nutrients. When these RBCs are fewer in number than what is
needed anemia occurs in the body. There can be 3 primary
reasons: RBCs are lost due to some reason, the production of
RBCs is slower than what is needed and lastly the body is
destroying the RBCs. Different types of anemia are linked to at
least one of these causes.
The bone marrow replaces small amounts of blood is lost due
to some reason without making a person anemic. But in cases
where considerable amount of blood flows in small amount of
time as a result of an injury due to a serious example for
instance, it may not be possible for bone marrow to replace
RBCs so quickly resulting in anemia. Also, losing small amounts
of blood over long periods of time may also lead to anemia.
Example of this situation can be seen in girls who get heavy
periods attributed mainly to deficiency of iron in the
diet.
Anemia due to iron deficiency is the most common kind of
anemia in the United States. It occurs mainly due to lack of
iron in a persons diet. A teen with iron deficiency would have
lower hemoglobin production and consequently lower RBCs. When
the production of RBCs is low the person is regarded as anemic.
The signs of anemia are paleness and tiredness. There can be
other reasons as to why enough RBCs are not produced in the
body. Folic acid and Vitamin B-12 are also essential to produce
RBCs. Getting these in adequate quantities is this important
too. There can be a problem with bone marrows working too
resulting in anemia.
Hemolytic anemia occurs when a person has RBCs whose
lifespan is shorter. The bone marrow may not be able to produce
new blood cells if the blood cells die too early. This can
result due to many reasons including person having disorders
like sphenocytosis or sickle cell anemia. In some cases the
immune system of the body may itself destroy the RBCs. In some
cases certain antibodies can form in the blood as a result of
reaction to certain drugs or infections and may attack the
RBCs.
Teens get anemia as they grow rapidly the amount of iron
intake may not be enough to keep up with the pace of the growth
as it needs more nutrients in this process. In the case of
girls they need more iron after puberty and are at risk due to
heavy blood loss during menstrual periods. In some cases
pregnancies also leads to anemia. Also, teens who diet
excessively to lose weight may also be at risk of having iron
deficiency. Meat eaters especially red meat eaters are at less
risk compared to vegetarians as meat has rich iron in it.
