Marasmus is best described as what type of malnutrition?

• A. Excess protein intake
• B. Chronic vitamin deficiency
• C. Primary mineral deficiency
• D. Protein-energy malnutrition due to starvation

Answer: (D)

Marasmus is a form of protein-energy malnutrition caused by chronic energy (calorie) deficiency, typically from prolonged undernutrition or starvation. The body uses fat stores and then lean tissue to meet energy needs, leading to severe wasting and very low weight for age, with little or no edema. This distinguishes marasmus from other conditions that involve micronutrient deficiencies or excess nutrient intake. So, marasmus is best described as protein-energy malnutrition due to starvation.
