Summary
Marasmus is a form of severe malnutrition characterized by energy deficiency. It is typically characterized by muscle wasting, fat depletion, and impaired function of the organs. Infants and young children are at the highest risk for developing marasmus, as they require an adequate intake of protein and other nutrients to grow and develop properly.
Marasmus is different from kwashiorkor in that kwashiorkor is protein deficiency with adequate energy intake, whereas marasmus is inadequate energy intake in all forms, including protein.
