Cause And Effects Of Anorexia Essay

A serious and life-threatening form of disordered eating that involves the rigid restriction of food in order to achieve the lowest weight possible is known as anorexia nervosa. Sufferers of this condition possess an intense fear of gaining weight or becoming overweight and, as a result, go to great lengths to abstain from the consumption of food. Additionally, those battling this mental illness are known to abuse substances, such as stimulants, diet pills, laxatives, and diuretics, to prevent the body from absorbing nutrients as another method to avoid weight gain.

According to the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), there are two types of anorexia nervosa:

Restricting type: The most widely known form of this disorder, the restricting type involves rigid dieting, fasting, and excessive exercising to prevent weight gain.

Binge eating/purging type: Those with the binge eating/purging type of anorexia nervosa may have episodes in which they overeat and induce vomiting afterwards as a means of ridding the body of the food that was consumed.

The monumental mental and physical health risks associated with this illness are quite costly and can lead to death if treatment is not sought and implemented as soon as symptoms become apparent. Many sufferers of anorexia nervosa require both therapeutic and medical interventions in order to overcome this potentially fatal mental illness. A key thing to understand, however, is that there are viable options for care in existence that can save the lives of those battling anorexia nervosa.


Anorexia nervosa is believed to affect more women than men. And while prevalence rates of this condition are higher among females, research has found that 10-15 percent of all adults diagnosed with this illness are male, though experts believe that many men do not seek treatment for this condition as often as women. Anorexia nervosa has the highest mortality rate when compared to other eating disorders and sufferers of this condition are often at greater risk for developing self-injurious behaviors, ideations of suicide, and attempting suicide when compared to individuals with other forms of disordered eating. In fact, it is estimated that for every 100,000 suicides that occur yearly, 12 of those individuals battle anorexia nervosa.

Causes and Risk Factors for Anorexia Nervosa

There are several causes and risk factors that can make a person more vulnerable to the development of anorexia nervosa. The following elaborations on these causes and the listed risk factors briefly explain how someone can come to develop this life-threatening mental health condition.

Genetic: Similar to other mental illnesses, anorexia nervosa is known to possess a genetic component. This conclusion was made after it was realized by researchers that the disorder is known to occur more frequently among those with a family history of eating disorders, depressive disorders, and bipolar disorder. In lieu of this finding, it can be said that genetics are partially at work in the development of this mental illness.

Environmental: Experts in the field of mental health believe that a person’s environment can greatly impact whether or not an individual will develop symptoms synonymous with anorexia nervosa. For example, people who are part of cultures that value thinness and place a great deal of importance on maintaining certain weight expectations have a greater risk for developing this form of disordered eating. Furthermore, individuals of certain professions or those engaged in certain athletics in which physical appearance is prized also have an increased likelihood for developing anorexia nervosa. Lastly, men and women with a history of being victimized or enduring trauma are also more likely to battle this dangerous eating disorder.

Risk Factors:

  • Being female
  • Being in an environment or part of a culture that values thinness
  • Exposure to chronic stress
  • Personal history of being a victim of trauma, abuse, and/or neglect
  • Family history of disordered eating or other mental health conditions
  • Pre-existing mental health condition or conditions

What is Anorexia?

Anorexia Nervosa is a psychological and potentially life-threatening eating disorder. Those suffering from this eating disorder are typically suffering from an extremely low body weight relative to their height and body type.

Often referred to as BMI (Body Mass Index) is a tool that treatment providers often use to assess the appropriateness of body weight for an individual struggling with an eating disorder. Additionally, observations of eating patterns, exercise, and personality traits may give indications of an anorexic diagnosis. Those struggling with anorexia frequently fear gaining weight and have a distorted body image. They often believe they appear much heavier than they are.

Additionally, women and men who suffer from this eating disorder exemplify a fixation with a thin figure and abnormal eating patterns. Anorexia nervosa is interchangeable with the term anorexia, which refers to self-starvation and lack of appetite.

Major Types of Anorexia

There are two common types of anorexia, which are as follows:

  • Binge/Purge Type – The person struggling with this type of eating disorder will often purge after eating. This alleviates the fear of gaining weight and offsets some of the guilt of having ingested forbidden, or highly restricted food. The compensatory purge behavior by the individual with Binge/Purge Type anorexia may purge by exercising excessively, vomiting or abusing laxatives.
  • Restrictive – The individual suffering from restrictive anorexia is often perceived as highly self-disciplined. They restrict the quantity of food, calories and often high fat or high sugar foods. They consume far fewer calories than are needed to maintain a healthy weight. This is a heartbreaking form of self-starvation.

Though two classifications of this eating disorder exist, both types exhibit similar symptoms, such as an irrational fear of weight gain and abnormal eating patterns.

Causes of Anorexia

It has been said that genetics load the gun and environment pulls the trigger in eating disorders. This eating disorder is based on genetic predisposition, personality traits, and environmental factors.

Examples of environmental factors that would contribute to the occurrence of this eating disorder are:

  • The effects of the thinness culture in media, that constantly reinforce thin people as ideal stereotypes
  • Professions and careers that promote being thin and weight loss, such as ballet and modeling
  • Family and childhood traumas: childhood sexual abuse, severe trauma
  • Peer pressure among friends and co-workers to be thin or be sexy.

Examples of biological factors include:

  • Irregular hormone functions
  • Genetics (the tie between anorexia and one’s genes is still being heavily researched, but we know that genetics is a part of the story).

Anorexia Signs & Symptoms

An individual suffering from anorexia nervosa may reveal one or several signs and symptoms such as:

  • Chronic restrictive eating or dieting, beyond the norm
  • Rapidly losing weight or being significantly underweight and emaciated
  • Obsession with calories and fat contents of food
  • Engaging in ritualistic eating patterns, such as cutting food into tiny pieces, eating alone, and/or hiding food
  • Continued fixation with food, recipes, or cooking; the individual may cook intricate meals for others but refrain from partaking
  • Amenorrhea: an abnormal absence of menstruation, or loss of 3 consecutive menstrual cycles
  • Depression or lethargic stage
  • Development of lanugo: soft, fine hair that grows on face and body
  • Reported sensation of feeling cold, particularly in extremities
  • Loss or thinning of hair
  • Avoidance of social functions, family, and friends. May become isolated and withdrawn

Dieting Vs. Anorexia

Though the restrictive eating patterns that characterize this anorexic eating disorder are similar to dieting behaviors, there are stark differences between the two. The effects of the extreme behaviors resulting from this disease are far more devastating and consequential than any ill effects from dieting.

While someone may diet in an attempt to control weight, anorexia nervosa is often an attempt to gain control over one’s life and emotions, especially in the light of traumatic events or a chaotic environment.

While someone might diet in an attempt to lose weight as the primary goal, in anorexia they may diet because they perceive losing weight as a way to achieve happiness and self-mastery.

Anorexia Treatment

Seeking anorexia recovery from a well-qualified team of eating disorder specialists, consisting of a therapist, physician and nutritionist are recommended. Effective, holistic eating disorder treatment of anorexia involves three necessary components:

  • Medical: The highest priority in the treatment of anorexia nervosa is addressing any serious health issues that may have resulted from the eating disordered behaviors, such as malnutrition, electrolyte imbalance, amenorrhea and an unstable heartbeat.
  • Nutritional: This component encompasses weight restoration, implementation and supervision of a tailored meal plan, and education about normal eating patterns.
  • Therapy: The goal of this part of treatment is to recognize underlying issues associated with the eating disorder, address and heal from traumatic life events, learn healthier coping skills and further develop the capacity to express and deal with emotions.
