|
Hemorrhage, nutritional deficiency,
aplastic disorders, inherited disorders, chronic renal disease,
immune issues
|
|
General manifestations of anemia
|
Weakness & syncope due to
diministed O2 carrying capacity, pallor due to low blood volume &
blood pressure, hyperbilirubinemia & jaundice, splenomegaly due
to spleen breaking down bad RBCs
|
|
What happens in nutritional deficiency
anemia?
|
Red blood cells/erythrocytes fail to
mature
|
|
Iron deficiency anemia is also known as
|
Microcytic hypochromic anemia
|
|
In iron deficiency anemia the RBCs are
|
Small and pale
|
|
If iron is deficient...
|
Hemoglobin can't be formed and RBC
production slows
|
|
Pernicious anemia results from
|
Lack of vitamin B12 or lack of enzyme
needed to transport B12
|
|
Enzyme needed to transport B12 is
called
|
Intrinsic factor
|
|
Macrocytic/megaloblastic anemia
|
Giant, immature cells resulting from
lack of B12
|
|
Macrocytic/megaloblastic anemia is
characterized by:
|
Anisocytosis and poikilocytosis
|
|
Anisocytosis is:
|
Variation in RBC size
|
|
Poikocytosis is:
|
Variation in RBC shape
|
|
Manifestations of nutritional
deficiency anemias (7)
|
Neutropenia & thrombocytopenia,
,tingling, ataxia, dementia
|
|
Hyperbilirubinemia occurs because of
|
Excessive RBC breakdown and shortage
|
|
Neutropenia
|
Low white blood cell count
