Signs & Symptoms of Anorexia

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 anorexia nervosa. Sufferers of this condition are known to 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 Fifth Edition of the Diagnostic and Statistical Manual of Mental Disorders, 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 know, 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 ten to fifteen 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. Overall, it is believed that 24 million people meet diagnostic criteria for eating disorders, including anorexia nervosa. Anorexia nervosa, however, 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-threating 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 this 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 who possess 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 battling this dangerous eating disorder.
