Explanation

Marasmus is a form of severe protein-energy malnutrition, characterized by a lack of sufficient protein and calories in the diet.

It is most commonly seen in children under the age of 5, particularly in developing countries where access to nutritious food is limited.

Marasmus is caused by a severe deficiency of protein and calories, leading to:

• Wasting of muscles and tissues
• Weight loss
• Fatigue
• Weakness
• Poor growth and development
