Pathophysiological mechanism of iron deficiency anemia
Anemia is a condition that involves a lower number of red blood cells and the amount of hemoglobin in
the red blood
drops below normal, this prevents the body’s cells from getting adequate oxygen.
(Heuther & McCance,2017). Iron deficiency anemia is the most common form of anemia in both the
developed and developing countries. ( Heuter & McCance, 2017). IDA occurs when iron is depleted and
there is a reduction of hemoglobin synthesis, this can be caused by in adequate dietary intake or chronic
blood loss (Heuther & McCance, 2017). People at risk for developing IDA include people living in poverty,
females of child bearing age and children under 2 years of age due to their rapid growth.
IDA Development.
In the first stage, the body’s iron storage, used for blood cell reproduction is depleted. In the 2

phase is
where red blood cells that are deficient in iron is transported to the bone marrow where iron deficient
red cells blood begins.
In the third phase symptoms usually begins because iron deficient red blood cells
enters into venous circulation and this causes a decrease in hemoglobin. The body tissues do not
