Starvation

Starvation is a severe reduction in vitamin, nutrient, and energy intake, and is the most extreme form of malnutrition. In humans, prolonged starvation (in excess of 1-2 months) causes permanent organ damage and, eventually, death. The term "inanition" refers to the symptoms and effects of starvation.

According to the World Health Organization, hunger is the gravest single threat to the world's public health.According to the Food and Agriculture Organization of the United Nations, more than 25,000 people died of starvation every day in 2003,and as of 2001 to 2003, about 800 million people were chronically undernourished.The WHO also states that malnutrition is by far the biggest contributor to child mortality, present in half of all cases.Scientists say millions of people face starvation following an outbreak of a deadly new strain of blight, known as Ug99, which is spreading across the wheat fields of Africa and Asia

Symptoms

Individuals experiencing starvation lose substantial fat (adipose) and muscle mass as the body breaks down these tissues for energy. Catabolysis is the process (medical condition) of a body breaking down muscles and other tissues in order to keep vital systems working – vital systems such as the nervous system and heart muscle (myocardium). Catabolysis will not begin until there are no usable sources of energy coming into the body. Vitamin deficiency is also a common result of starvation, often resulting in anemia, beriberi, pellagra, and scurvy. These diseases collectively may cause diarrhoea, skin rashes, edema, and heart failure. Individuals are often irritable and lethargic as a result.

Atrophy (wasting away) of the stomach weakens the perception of hunger, since the perception is controlled by the percentage of the stomach that is empty. Victims of starvation are often too weak to sense thirst, and therefore become dehydrated.

All movements become painful due to atrophy of the muscles, and due to dry, cracked skin caused by severe dehydration. With a weakened body, diseases are commonplace. Fungi, for example, often grows under the esophagus, making swallowing unbearably painful.

The energy deficiency inherent in starvation causes fatigue and renders the victim more apathetic over time. Interaction with one's surroundings diminishes as the starving person becomes too weak to move or even eat.

Psychological effects of starvation

Through several reports and studies, scientists have discovered that starvation has many psychological effects on a person, in addition to its physiological effects.The most extensive and informative study on starvation's psychological effects is called the Minnesota Starvation-Rehabilitation Experiment, which was carried out from 1944-1946. The subjects of this experiment were thirty-two fully informed volunteers, ages twenty to thirty-three.Subjects experienced three phases of the experiment: twelve weeks of control period, twenty four weeks of semistarvation, and then twelve weeks of rehabilitation. During the control experiments the subjects were given 3,492 calories, during the period of semistarvation the calories were decreased to 1,570, and during the period of rehabilitation they were re-increased to normal levels. During the period of semistarvation, subjects were fed foods most likely consumed in European famine areas.The results of the starvation experiment were tested in many ways. According to Josef Brozek, author of Psychology of Human Starvation and Nutritional Rehabilitation, studies "ranged from intelligence and personality tests through ratings to purely descriptive material, provided by the experimenters' notes and diaries kept by the subjects".According to subjects of the semistarvation experiment, tiredness was the worst effect of the low calorie intake, followed by appetite, muscle soreness, irritability, apathy, sensitivity to noise, and hunger pain.Standard personality tests revealed that the starving individuals experienced a large rise in the "neurotic triad" -- hypochondriasis, depression, and hysteria. Also, the subjects of the experiment noticed a marked decrease in the drive for activity, and a remarkable decrease in sex drive. In peer evaluations, other experiment subjects noted great changes in subjects' personalities during the period of semistarvation.; In interviews years later, subjects reported that they felt that they had not returned to normal by the end of the three month recovery period.Subjects' own estimates of the time it took for recovery ranged from two months to two years.Many subjects reported that they grossly overate and put on fat after the experiment due to the urge to eat
