Kwashiorkor vs. Marasmus: Know the Difference
By Shumaila Saeed || Published on January 31, 2024
Kwashiorkor is malnutrition due to protein deficiency with adequate calorie intake, causing edema and liver enlargement; Marasmus results from overall calorie deficiency, leading to severe weight loss.
Key Differences
Kwashiorkor is caused primarily by a protein deficiency in the presence of adequate calorie intake, often resulting in edema and an enlarged liver. Marasmus results from a severe deficiency in overall calorie and nutrient intake, leading to extreme weight loss.

Kwashiorkor affects protein metabolism, impairing functions like enzyme production and immunity. Marasmus impacts overall metabolism, exhausting the body's energy reserves and leading to muscle and fat depletion.
