Final answer:
Victims of the type of protein-calorie malnutrition known as marasmus have a "skin and bones" appearance, which is caused by severe caloric deficiency leading to the use of fat and muscle as energy. Unlike kwashiorkor, which results primarily from protein deficiency, marasmus is prevalent in regions with famine or severe poverty, and requires interventions focused on improving nutrition.
Step-by-step explanation:
Victims of the type of protein-calorie malnutrition known as marasmus have a "skin and bones" appearance with little or no subcutaneous fat. This condition arises when there is a significant deficiency in caloric intake, leading to a state where the body uses up its fat and muscle reserves for energy. The symptoms include severe weight loss, stunted growth, and emaciation, resulting in a child appearing very thin and frail. Marasmus is particularly prevalent in areas experiencing famine or among children from impoverished families.
Kwashiorkor, on the other hand, is another form of protein-energy malnutrition that is characterized primarily by a lack of protein in the diet, even when calorie intake is adequate. It presents differently, with victims often showing edema of the ankles, feet, and abdomen, making them look swollen rather than emaciated.
Both marasmus and kwashiorkor are severe health conditions that can lead to various complications such as chronic diarrhea, muscle wasting, and in the most extreme cases, death. They are a common concern in developing countries and areas where people do not have access to a diverse and nutritious diet. It's crucial to address these conditions by improving nutritional education and food resources to affected populations.
