(from Greek meaning "to waste away"). Symptoms include extreme emaciation, diarrhea, anemia, and apathy. Women with marasmus usually stop ovulating and, subsequently, cannot become pregnant. The loss of insulating body fat makes people with marasmus highly vulnerable to death resulting from a drop incore body temperature when the air falls below 60-65º F. (15-18º C.). Young children who survive marasmus usuallyend up with short adult stature and some degree ofmental retardation. Unfortunately, marasmus is not a rare occurrence around the globe today. Approximately 31 million children die each year from undernutrition, and 178 million are stunted in their growth. About 1 billion people are now undernourished, and essentially the same number are overnourished and suffer the health problems related to obesity.

. Alsocontributing to this condition is an inadequate consumption of vitamins A and E as well as the minerals zinc and selenium. Typical symptoms of kwashiorkor include edema (or swelling) due tofluid retention (especially in the abdomen), stick-like legs and arms with little fat or muscle mass, apathy, and loss of hair and skin pigmentation in patches. As in the case of marasmus, children with kwashiorkor are likely to be apathetic and have impaired immune systems which reduces their ability to fight off infections. If a child survives kwashiorkor, they are likely to have their growth retarded.
