Anemia Flashcards
anemia
lack or loss of red blood cells
aplastic anemia
decreased RBCs and WBCs in the blood
caused by benzene poisoning
associated with degeneration of bone marrow
decreased production of bone marrow can occur in two ways
nutritional or bone marrow suppression
nutritional type 1: iron deficiency
mcc = chronic blood loss (menses)
microcytic
hypochromic
nutritional type 2: pernicious
lack of intrinsic factor
gastritis can be a cause
nutritional type 3: folic acid
in pregnandy
megaloblastic anemia
leads to spina bifida occulta
nutritional type 4: B12
seen in vegetarians
macrogcytic
hypochromic
bone marrow suppresssion type 1: toxins
benzene-> aplastic anemia
bone marrow suppression type 2:chemotherapy
.
loss of blood:
chronic blood loss
decrease iron=microcytic, hypocrhomic anemia
loss of blood:
hemorrhage
normochromic
normocytic anemia
loss of blood:
hemolytic breakdown
do to sickle cell or malaria

aka “Cooleys Anemia”
“Homozygous Beta Thalassemia”
“Midterannean anemia”
