What kind of anemia is characterized by inadequate production of red blood cells due to bone marrow failure?

• A. Hemolytic anemia
• B. Aplastic anemia
• C. Iron-deficiency anemia
• D. Vitamin B12 deficiency anemia

Answer: (B)

Aplastic anemia is characterized by the failure of the bone marrow to produce an adequate number of blood cells, including red blood cells, white blood cells, and platelets. This condition can arise from various factors such as exposure to toxins, radiation, certain medications, or autoimmune processes that target the bone marrow. Because of this failure, individuals with aplastic anemia experience symptoms associated with low levels of red blood cells, such as fatigue, weakness, and increased susceptibility to infections and bleeding due to the reduced numbers of white blood cells and platelets. In contrast, hemolytic anemia results from the premature destruction of red blood cells, iron-deficiency anemia is due to insufficient iron needed for red blood cell production, and vitamin B12 deficiency anemia arises from a lack of vitamin B12, which is essential for proper red blood cell formation. These conditions involve different underlying mechanisms compared to aplastic anemia, which is specifically linked to the bone marrow's inability to produce blood cells.
