Marasmus is a form of severe protein-energy malnutrition characterized by energy deficiency. Other PEMs include kwashiorkor and cachexia.
A child with marasmus looks emaciated and body weight may be reduced to less than 80% of the normal weight for that height. Marasmus occurrence increases prior to age 1 whereas kwashiorkor occurrence increases after 18 months.
[edit] Signs and Symptoms
The malnutrition associated with marasmus leads to extensive tissue and muscle wasting, as well as variable edema. Other common characteristics include dry skin, loose skin folds hanging over the glutei, axillae, etc. There is also drastic loss of adipose tissue from normal areas of fat deposits like buttocks and thighs. The afflicted are often fretful, irritable, and voraciously hungry.
[edit] Treatment
It is necessary to treat not only the symptoms but also the complications of the disorder, including infections, dehydration and circulation disorders, which are frequently lethal and lead to high mortality if ignored.
Ultimately, marasmus progresses to the point of no return when the body's machinery for protein synthesis, itself made of protein, has been degraded. At this point, attempts to correct the disorder by giving food or protein will fail to prevent death.
[edit] Causes
Marasmus is caused by a severe deficiency of nearly all nutrients, especially protein and calories.
