Default Culled from Wikipedia

Marasmus is a form of severe malnutrition characterized by energy deficiency. A child with marasmus looks emaciated. Body weight may be reduced to less than 80% of the average weight that corresponds to the height.[citation needed] Marasmus occurrence increases prior to age 1, whereas kwashiorkor occurrence increases after 18 months. It can be distinguished from kwashiorkor in that kwashiorkor is protein wasting with the presence of edema.

The prognosis is better than it is for kwashiorkor.[1]

There is no edema in marasmus!

In kwashiorkor there is decrease in visceral protein that is why edema develops
In marasmus there is major impact on somatic protein with normal visceral protein and no edema
Everything is possible for him who believes (MARK 9:23)
