Types of Anemias:
1. Anemia Secondary to Renal Disease: Anemia d/t lack of erythropoietin.
2. Iron Deficiency Anemia: Anemia resulting from low iron levels; the iron stores are depleted first, followed by hemoglobin stores.
3. Aplastic Anemia: Bone marrow suppression of new stem cell production resulting in deficiency of circulating WBCs, platelets, and/or RBCs. Can be d/t medications, viruses, toxins, and/or radiation exposure.
4. Pernicious Anemia: anemia d/t lack of dietary intake or absorption of vitamin B12.
5. Folic Acid Deficiency Anemia: Anemia d/t folic acid deficiency. Symptoms similar to vitamin B12 deficiency, but nervous system functions remain normal.
6. Hemolytic Anemia: A group of anemias that occur when the bone marrow is unable to increase production to make up for the premature destruction of RBCs. Sickle cell and Thalassemia are hemolytic anemias.
7. Sickle Cell Anemia: A genetic defect found in clients of African American or Mediterranean origin, in which the Hgb molecule assumes a sickle shape and delivers less oxygen to tissues; the sickle cells become lodged in the blood vessels, especially the brain and the kidneys.
8. Thalasemmia: Inherited blood disorder in which the body makes an abnormal form of hemoglobin, resulting in excessive destruction of RBCs, which leads to anemia.
