How does Marasmus primarily differ from Kwashiorkor in terms of nutritional deficiency?

Marasmus primarily differs from Kwashiorkor in that it involves an inadequate intake of both protein and calories. Individuals suffering from Marasmus experience severe energy deficiency, leading to significant weight loss and wasting of muscle and fat tissues. This condition arises when there is a prolonged lack of adequate nutrition, specifically both macronutrients—carbohydrates and proteins.

In contrast, Kwashiorkor is characterized by significant protein deficiency while caloric intake may still be sufficient. It often presents with symptoms such as edema, which are not seen in Marasmus. Understanding these distinctions is crucial for identifying and treating these forms of malnutrition effectively.
