Marasmus is a form of malnutrition. It happens in people (especially children) who do not get enough food. A healthy person gets energy from eating food, especially foods with protein and fat in them. Because a person with marasmus is not getting enough food, they do not get the energy they need to survive. This is due to deficiency of both proteins and calories. Generally, this disease when there is an immediate second pregnancy or repeated child births. Lean and weak, swelling limbs, less developed muscles, dry skin, diarrhoea, etc.., are the symptoms of this disease.
