Fatty change in liver, myocardium, and kidney may occur due to hypoxia from anemia. Which organs show these changes?

• A. The liver, heart, and kidney may show fatty change
• B. The brain only shows fatty change
• C. No organ shows fatty change
• D. The lungs show fatty change

Answer: (A)

Fatty change from hypoxic injury hinges on reduced oxygen delivery leading to impaired oxidative metabolism and lipid processing in cells. When anemia lowers oxygen delivery, liver, heart, and kidney are especially susceptible because their cells rely heavily on aerobic respiration to burn fats and export triglycerides. In the liver, hypoxia slows fatty acid oxidation and vesicular export of lipids, causing triglycerides to accumulate in hepatocytes as fat droplets. In the heart, cardiomyocytes under low-oxygen conditions accumulate lipids as the remaining energy pathways falter. The kidney, particularly tubular epithelial cells, can also show lipid vacuolization under hypoxic stress as cells struggle to metabolize fats and maintain energy. The brain is highly sensitive to hypoxia but tends to show edema and neuronal injury rather than fatty change, and the lungs are not typically a site of fatty change in this anemia-related hypoxia scenario. So the organs that commonly exhibit fatty change under these conditions are the liver, heart, and kidney.
