10 Differences between Kwashiorkor and Marasmus (Kwashiorkor vs Marasmus)

When balanced diet is not consumed by a person for a sufficient length of time, it leads to nutritional deficiencies or disorders. The nutritional status is called malnutrition. Protein Energy Malnutrition (PEM). PEM is classified as Kwashiorkor and Marasmus. Kwashiorkor or edematous PEM and Marasmus (Greek; “waste”) is nonedematous PEM.

Difference Between Marasmus And Kwashiorkor In Table Form
Kwashiorkor is an African word that means weaning disease. It is a protein energy malnutrition (PEM). It occurs due to deficiency of proteins in the diet of children, through the diet may contain adequate amount of carbohydrates. It is most common among children between 1 to 3 years of age. The symptoms of Kwashiorkor are oedema, stunted growth, mental retardation, wrinkled skin, thin legs, bulged eyes, protruded belly etc.
