Iron deficiency anemia is a common cause of anemia that develops when body stores of an iron drop too low to support normal red blood cell (RBC) production. Inadequate dietary iron, impaired iron absorption, bleeding, or loss of body iron in the urine may be the cause. Iron is a key part of red blood cells. Without iron, the blood cannot carry
Macrocytic anemia is a type of blood disorder where some of the red blood cells are much larger than usual. Sometimes a B-12 deficiency can cause macrocytic anemia. Symptoms of macrocytic anemia Microcytic anemia happens when your red blood cells are smaller than usual because they don’t have enough hemoglobin. Hemoglobin is a protein in your red blood cells. It helps red blood cells carry oxygen throughout your body. Healthcare providers treat microcytic anemia by identifying and treating the condition that causes microcytic anemia. Alcohol’s adverse effects on the blood-building, or hematopoietic, system are both direct and indirect. The direct consequences of excessive alcohol consumption include toxic effects on the bone marrow; the blood cell precursors; and the mature red blood cells (RBC’s), white blood cells (WBC’s), and platelets. Alcohol’s indirect effects Polycythemia is an increased number of red blood cells in the blood. In polycythemia, the levels of hemoglobin (Hgb), hematocrit ( Hct ), or red blood cell (RBC) count may be elevated when measured in the complete blood count ( CBC ), as compared to normal. Hemoglobin levels greater than 16.5 g/dL (grams per deciliter) in women and greater thanHematocrit is the percentage of red blood cells in a person‘s blood. A typical hematocrit range in adults is 36–54%. However, age, sex, and health conditions can influence hematocrit levels.tiFMooy.
