Which anemia is caused due to Microcytic, hypochromic red blood cells?
Show Hint
- Pernicious anemia
- Aplastic anemia
- Iron deficiency anemia
- Hemolytic anemia
The Correct Option is C
Solution and Explanation
- Microcytic, hypochromic anemia refers to red blood cells (RBCs) that are smaller than normal (microcytic) and have reduced hemoglobin content (hypochromic), which appears pale under a microscope.
- The most common cause of this type of anemia is Iron deficiency anemia, which results from insufficient iron for hemoglobin synthesis.
- Iron is essential for the formation of hemoglobin, and its deficiency leads to impaired hemoglobin production, producing smaller, less pigmented RBCs.
Analysis of other options:
- (a) Pernicious anemia: A type of macrocytic anemia caused by vitamin B\textsubscript{12} deficiency due to intrinsic factor absence.
- (b) Aplastic anemia: A normocytic normochromic anemia caused by bone marrow failure, not related to cell size or color.
- (d) Hemolytic anemia: Characterized by increased RBC destruction, often with normocytic cells; not microcytic-hypochromic.
