What is a person suffering from marasmus?

A person suffering from marasmus experiences severe malnutrition, typically due to a significant deficiency in calories and protein. This condition often manifests in extreme weight loss, wasting of muscle and fat, and stunted growth, particularly in children. Symptoms may include dry skin, brittle hair, and a weakened immune system. Marasmus is often associated with poverty, inadequate food supply, and chronic illnesses.
