Anorexia Nervosa
Eating disorders are grouped in three different categories: 1. Refusing to maintain a minimally normal body weight (anorexia nervosa), 2. Bingeing and purging (bulimia nervosa) 3. Bingeing without purging (binge eating disorder). All types of eating disorders are dramatically more common in women than in men. Anorexia Nervosa This condition is characterized by a distorted body image, a great fear of becoming obese, refusal to maintain a minimally normal body weight, and in women, the absence of menstrual periods. Hereditary factors have been shown to play a role in the development of anorexia nervosa. Social factors are also important. The desire to be thin is obsessive in Western society, and obesity is considered unattractive, unhealthy, and generally undesirable. Even before adolescence, children are aware of these beliefs and almost seventy percent of all adolescent girls’ diet or take other measures to control their weight. Yet only a small percentage of these girls develop anorexia nervosa. Other factors, such as physiologic susceptibility, probably predispose certain people to developing anorexia nervosa. In areas where starvation is common or genuine food shortage occur, anorexia nervosa is rare. Approximately ninety five percent of people who have anorexia nervosa are female. This disorder usually begins in adolescence, seldom earlier, and less commonly in adulthood. Anorexia nervosa principally affects people in middle and upper socioeconomic classes. In Western society, the number of people who have this disorder seems to be on the increase. The latest estimates show that this condition affects about 1% of girls ages 12 to 18. Symptoms Anorexia nervosa may be mild and transient or severe and persistent. Because numerous people who develop anorexia nervosa are meticulous, compulsive, and intelligent, with very high standards for achievement and success, an eating disorder may easily go undetected. The first indication of the looming disorder may be a subtle increased concern with diet and body weight. Such concerns seem out of place, because most people who have anorexia nervosa are already thin. Obsession and anxiety about weight increase as the person becomes thinner. Even when emaciated, the person claims to feel fat, denies that anything is wrong, does not complain about weight loss, and usually does not seek medical attention until a concerned relative or family member takes drastic action. The literal meaning of Anorexia is “lack of appetite,” but people who have anorexia nervosa are actually hungry and preoccupied with food. They count calories and study diets; they hoard, conceal and waste food on purpose; they collect recipes; and they prepare elaborate meals for others. About fifty percent of people with this condition binge and then purge by vomiting or taking laxatives. The other half simple limit the amount of food they consume. They also commonly fib about the amount of food they eat and conceal their vomiting and peculiar dietary habits. Many also take diuretics to treat perceived bloating. Women with anorexia nervosa stop having periods, sometimes before losing much weight. Women and men with the disorder may lose interest in sex. Typically, they have a low heart rate, low blood pressure, low body temperature, swelling of tissues caused by fluid accumulation (edema), and fine, soft hair or excessive body and facial hair. People with anorexia nervosa who become very thin tend to remain active, often exercising excessively to control their weight. Until they become emaciated, however, they have few symptoms of nutritional deficiencies. Depression is common. Hormonal changes resulting from anorexia nervosa include noticeably reduced levels or estrogen (in women) and thyroid hormone and increased levels of cortisol (the stress hormone). If a person becomes seriously malnourished, every major organ system in the body is likely to become affected. When weight loss has been severe or rapid – for example, more than twenty five percent below the ideal body weight - restoring body weight quickly is vital; such weight loss and the associated changes in electrolytes and fluid balance can be life threatening. Problems with heart and with fluids and electrolytes (chloride, potassium, sodium) are the most dangerous. The heart gets weaker and pumps less blood through the body. The person may become dehydrated and susceptible to fainting. The blood may become alkaline (a condition called metabolic alkalosis), and potassium levels in the blood may decrease. Vomiting and taking laxatives and diuretics can worsen the situation. Sudden death, probably from abnormal heart rhythms, may occur. Diagnosis and Treatment Anorexia nervosa is usually diagnosed on the basis of severe weight loss and the characteristic psychologic symptoms. The classic person with this condition is an adolescent girl who has lost at least fifteen percent of her body weight, has a fear of obesity, stops having menstrual periods, is in denial of being sick, while otherwise appearing to be healthy. Treatment has two phases: short term intervention to restore body weight and save the person’s life and long term therapy to improve psychologic functioning and avoid relapse. The initial treatment of severe or rapid weight loss is best provided in a hospital or medical facility where experienced staff members firmly but gently encourage the person to eat. Rarely, the person is fed intravenously or by a tube inserted through the nose and passed into the stomach. Sometimes doctors confine those with severe cases in the hospital against their will after obtaining proper legal authorization from a parent, guardian, or the court. When the person’s nutritional status improves and stabilizes, long term therapy is begun. Treatment is aimed at establishing a calm, concerned, stable environment while encouraging the consumption of an adequate amount of food. The treatment may include individual, group, and family psychotherapy as well as drug therapy. Combined treatment by the family doctor and a therapist often helps, and consultation with or referral to a specialist in the field of eating disorders is wise. When depression is diagnosed, antidepressants are prescribed. Certain antidepressants, chiefly selective serotonin reuptake inhibitors, are useful for preventing relapse after weight has been restored. As many as ten to twenty percent of people diagnosed with anorexia nervosa die of it and its complications, which include fluid and electrolyte abnormalities, heart failure, and suicide resulting from depression. However, because mild cases may not be diagnosed, no one knows exactly how many people have anorexia nervosa or what percentage die of it.
