What condition is caused by impaired bone marrow activity?

• A. Sickle cell disease
• B. Aplastic anemia
• C. Thrombocytopenia
• D. Chronic myeloid leukemia

Answer: (B)

Aplastic anemia is a condition characterized by the failure of the bone marrow to produce adequate amounts of blood cells, which includes red blood cells, white blood cells, and platelets. This impairment in bone marrow activity can lead to a variety of symptoms, such as fatigue, increased susceptibility to infections, and bleeding problems due to reduced levels of these critical components of blood. The underlying issue in aplastic anemia typically involves damage to the bone marrow, which may be caused by autoimmune disorders, exposure to certain chemicals or radiation, viral infections, or even inherited conditions. The result is a diminished ability of the bone marrow to generate essential blood cells, leading to the clinical picture observed in patients. In contrast, conditions such as sickle cell disease involve abnormalities in hemoglobin rather than direct bone marrow impairment, while thrombocytopenia refers specifically to low platelet counts that may arise from various causes, including bone marrow issues or peripheral destruction. Chronic myeloid leukemia represents a malignancy of the bone marrow leading to overproduction of abnormal white blood cells, again differing from the non-production characteristic of aplastic anemia.
