anemia
Deficiency in erythrocytes or hemoglobin. The most common type of anemia is iron deficiency anemia; it is caused by a lack of iron, which is required for hemoglobin production.
Other types of anemia include:
aplastic anemia
hemolytic anemia
pernicious anemia
sickle cell anemia
thalassemia
hemochromatosis
Excess iron deposits throughout the body.
polycythemia vera
General increase in red blood cells (erythremia).
hemophilia
Excessive bleeding caused by hereditary lack of blood clotting factors (factor VIII or IX) necessary for blood clotting.
purpura
Multiple pinpoint hemorrhages and accumulation of blood under the skin.
leukemia
Increase in cancerous white blood cells (leukocytes).
Four types of leukemia are:
Acute myelogenous (myelocytic) leukemia (AML)
Acute lymphocytic leukemia (ALL)
Chronic myelogenous (myelocytic) leukemia (CML)
Chronic lymphocytic leukemia (CLL)
granulocytosis
Abnormal increase in granulocytes in the blood
mononucleosis
Infectious disease marked by increased numbers of mononuclear leukocytes and enlarged cervical lymph nodes.
multiple myeloma
Malignant neoplasm of bone marrow.
aplastic anemia
hemolytic anemia
pernicious anemia
Lack of mature erythrocytes caused by inability to absorb vitamin B
