The Cause and Effects of Anorexia Essay

Anorexia nervosa, commonly referred to simply as anorexia, is one type of eating disorder. More importantly, it is also a psychological disorder. Anorexia is a condition that goes beyond out-of-control dieting. A person with anorexia often initially begins dieting to lose weight. Over time, the weight loss becomes a sign of mastery and control. The drive to become thinner is actually secondary to concerns about control and/or fears relating to one’s body.

The individual continues the endless cycle of restrictive eating, often accompanied by other behaviors such as excessive exercising or the overuse of diet pills, laxatives, and/or enemas in order to reduce body weight, often to a point close to starvation in order to feel a sense of control over his or her body. This cycle becomes an obsession and a type of addiction. Approximately 95% of those affected by anorexia are female, but males can develop the disorder as well. While anorexia typically begins to manifest itself during early adolescence, it is also seen in young children and adults. In the U.

S. , it is estimated that about one out of every 100 adolescent girls has the disorder. Caucasians are more often affected than people of other racial backgrounds, and anorexia is more common in middle and upper socioeconomic groups. According to the U. S. National Institute of Mental Health (NIMH), an estimated 0. 5%-3. 7% of women will suffer from this disorder at some point in their lives. Many experts consider people for whom thinness is especially desirable, or a professional requirement (such as athletes, models, dancers, and actors), to be at risk for eating disorders such as anorexia nervosa.

At this time, no definite cause of anorexia nervosa has been determined. However, research within the medical and psychological fields continues to explore possible causes. Studies suggest that a genetic component may play a more significant role in determining a person’s susceptibility to anorexia than was previously thought. Researchers are currently attempting to identify the particular genes that might affect a person’s tendency to develop this disorder, and preliminary studies suggest that a gene located at chromosome 1p seems to be involved in determining a person’s susceptibility to anorexia nervosa.

Other evidence had pinpointed a dysfunction in the part of the brain, the hypothalamus (which regulates certain metabolic processes), as contributing to the development of anorexia. Other studies have suggested that imbalances in neurotransmitter levels in the brain may occur in people suffering from anorexia. Feeding problems as an infant, a general history of under eating, and maternal depressive symptoms tend to be risk factors for developing anorexia. Other personal characteristics that can predispose an individual to the development of anorexia include a high level of negative feelings and perfectionism.

For many individuals with anorexia, the destructive cycle begins with the pressure to be thin and attractive. A poor self-image compounds the problem. People who suffer from any eating disorder are more likely to have been the victim of childhood abuse. While some professionals remain of the opinion that family discord and high demands from parents can put a person at risk for developing this disorder, the increasing evidence against the idea that families cause anorexia has mounted such that professional mental-health organizations no longer ascribe to that theory.

Possible factors that protect against the development of anorexia include high maternal body mass index as well as personal high self-esteem. Anorexia nervosa can be a difficult disorder to diagnose, since individuals with anorexia often attempt to hide the disorder. Denial and secrecy frequently accompany other symptoms. It is unusual for an individual with anorexia to seek professional help because the individual typically does not accept that she or he has a problem. In many cases, the actual diagnosis is not made until medical complications have developed.

The individual is often brought to the attention of a professional by family members only after marked weight loss has occurred. When anorexics finally come to the attention of the health-care professional, they often lack insight into their problem despite being severely malnourished and may be unreliable in terms of providing accurate information. Therefore, it is often necessary to obtain information from parents or other family members in order to evaluate the degree of weight loss and extent of the disorder.

Health professionals will sometimes administer questionnaires for anorexia as part of screening for the disorder. Anorexia can have dangerous psychological and behavioral effects on all aspects of an individual’s life and can affect other family members as well. The individual can become seriously underweight, which can lead to depression and social withdrawal. The individual can become irritable and easily upset and have difficulty interacting with others. Sleep can become disrupted and lead to fatigue during the day. Attention and concentration can decrease. Most individuals with anorexia become obsessed with food and thoughts of food. They think about it constantly and become compulsive about eating rituals. They may collect recipes, cut their food into tiny pieces, prepare elaborate calorie-laden meals for other people, or hoard food. Additionally, they may exhibit other obsessions and/or compulsions related to food, weight, or body shape that meet the diagnostic criteria for an obsessive compulsive disorder. Other psychiatric problems are also common in people with anorexia nervosa, including affective (mood) disorders, anxiety disorders, and personality disorders.

Generally, individuals with anorexia are compliant in every other aspect of their life except for their relationship with food. Sometimes, they are overly compliant, to the extent that they lack adequate self-perception. They are eager to please and strive for perfection. They usually do well in school and may often overextend themselves in a variety of activities. The families of anorexics often appear to be “perfect. ” Physical appearances are important to them. Performance in other areas is stressed as well, and they are often high achievers.

While control and perfection are critical issues for individuals with anorexia, aspects of their life other than their eating habits are often found to be out of control as well. Many have, or have had at some point in their lives, addictions to alcohol, drugs, or gambling. Compulsions involving sex, exercising, housework, and shopping are not uncommon. In particular, people with anorexia often exercise compulsively to speed the weight-loss process. All of these features can negatively affect one’s daily activities. Diminished interest in previously preferred activities can result.

Some individuals also have symptoms that meet the diagnostic criteria for a major depressive disorder. Most of the medical complications of anorexia nervosa result from starvation. Few organs are spared the progressive deterioration brought about by anorexia. Heart and circulatory system: Although not life-threatening, an abnormally slow heart rate (bradycardia) and unusually low blood pressure (hypotension) are frequent manifestations of starvation and are commonly associated with anorexia. Of greater significance are disturbances in the heart rhythm (arrhythmia).

A reduction in the work capacity of the heart is associated with severe weight loss and starvation. * Gastrointestinal complications are also associated with anorexia. Constipation and abdominal pain are the most common symptoms. The rate at which food is absorbed into the body is slowed down. Starvation and overuse of laxatives can seriously disrupt the body’s normal functions involved in the elimination process. While liver function is generally found to be normal, there is evidence of changes in enzyme levels and overall damage to the liver.

The glandular (endocrine) system in the body is profoundly affected by anorexia. The complex physical and chemical processes involved in the maintenance of life can be disrupted, with serious consequences. Disturbances in the menstrual cycle are frequent, and secondary amenorrhea (absence of menstrual periods) affects about 90% of adolescent girls with anorexia. Menstrual periods typically return with weight gain and successful treatment. Hormonal imbalances are found in men with anorexia as well.

Continual restrictive eating can trick the thyroid into thinking that the body is starving, causing it to slow down in an attempt to preserve calories. Kidney (renal) function may appear normal. However, there are significant changes in kidney function in many people with anorexia, resulting in increased or decreased urination or potentially fatal potassium deficiency. Bone density loss (osteopenia or thinning of the bones) is a significant complication of anorexia, since women acquire 40%-60% of their bone mass during adolescence. Studies have shown that bone loss can occur fairly rapidly in girls with anorexia.

While some studies have shown that bone density may be restored if overall health improves and anorexia is successfully treated, other studies suggest that an increased risk for fracture may persist later in life. Anorexics who use a large quantity of laxatives or who frequently vomit are at great risk for electrolyte imbalance, which can have life-threatening consequences. Anemia is frequently found in anorexic patients. In addition to having fewer red blood cells, people with anorexia tend to have lower numbers of white blood cells, which play a major role in protecting the body from developing infections.

Suppressed immunity and a high risk for infection are suspected but not clinically proven. Physical symptoms, other than the obvious loss of weight, can be seen. Anorexia can cause a lower body temperature as well as dry, flaky skin that takes on a yellow tinge. Fine, downy hair grows on the face, back, arms, and legs. Despite this new hair growth, loss of hair on the head is not uncommon. Nails can become brittle. Frequent vomiting can erode dental enamel and eventually lead to tooth loss. Anorexia may be treated in an outpatient setting or hospitalization may be necessary.

For an individual with severe weight loss that has impaired organ function, hospital treatment must initially focus on correction of malnutrition, and intravenous feeding or tube feeding that goes past the mouth may be required. A gain of between 1 to 3 pounds per week is a safe and attainable goal when malnutrition must be corrected. Sometimes weight gain is achieved using schedules for eating, decreased physical activity, and increased social activity, either on an inpatient or outpatient basis. The overall treatment of anorexia, however, must focus on more than weight gain.

There are a variety of treatment approaches dependent upon the resources available to the individual. Because of increasing insurance restrictions, many patients find that a short hospitalization followed by a day treatment program is an effective alternative to longer inpatient programs. Most individuals, however, initially seek outpatient treatment involving psychological as well as medical intervention. It is common to engage a multidisciplinary treatment team consisting of a medical-care provider, a dietician or nutritionist, and a mental-health-care provider.

Different kinds of psychological therapy have been employed to treat people with anorexia. Individual therapy, cognitive behavior therapy, group therapy, and family therapy have all been successful in the treatment of anorexia. In adolescents, research shows that the Maudsley model of family therapy can be particularly effective in treating this disorder in this population. In contrast to many past approaches to treatment, the Maudsley model approaches the family of the individual with anorexia as part of the solution rather than part of the reason their loved one has the disorder.

With ongoing specific guidance from the professional mental-health team, this approach has the family actively help their loved one eat in a healthier manner. Any appropriate treatment approach addresses underlying issues of control, perfectionism, and self-perception. Family dynamics are explored. Nutritional education provides a healthy alternative to weight management for the patient. Group counseling or support groups often assist the individual in the recovery process. The ultimate goal of treatment should be for the individual to accept herself/himself and lead a physically and emotionally healthy life.

Anorexia is among the psychiatric conditions that have the highest mortality rate, with an estimated 6% of anorexia victims dying from complications of the disease. The most common causes of death in people with anorexia are medical complications of the condition, including cardiac arrest and electrolyte imbalances. Suicide is also a cause of death in people with anorexia. In the absence of any coexisting personality disorder, younger individuals with anorexia tend to do better over time than their older counterparts. Early diagnosis and treatment can improve the overall prognosis in an individual with anorexia.

Despite most psychiatric medications having little effect on the symptoms that are specific to anorexia, the improvement in associated symptoms (for example, anxiety and depression) can have a powerful, positive effect on the improvement that individuals with anorexia show over time. With appropriate treatment, about half of those affected will make a full recovery. Some people experience a fluctuating pattern of weight gain followed by a relapse, while others experience a progressively deteriorating course of the illness over many years, and still others never fully recover.

It is estimated that about 20% of people with anorexia remain chronically ill from the condition. As with many other addictions, it takes a day-to-day effort to control the urge to relapse. Many individuals will require ongoing treatment for anorexia over several years, and some may require treatment over their entire lifetime. Factors that seem to predict more difficult recovery from anorexia include vomiting and other purging behaviors, bulimia, and symptoms of obsessive personality disorder. The longer the disease goes on, the more difficult it is to treat as well.
