Anorexia nervosa is an eating disorder characterized by immoderate food restriction and irrational fear of gaining weight, as well as a distorted body self-perception. Ittypically involves excessive weight loss. Anorexia nervosa usually develops during adolescence and early adulthood.[1] Due to the fear of gaining weight, people with thisdisorder restrict the amount of food they consume. This restriction of food intake causes metabolic and hormonal disorders.[2] Outside of medical literature, the termsanorexia nervosa and anorexia are often used interchangeably; however, anorexia is simply a medical term for lack of appetite and people with anorexia nervosa do not infact, lose their appetites.[3]
People suffering from anorexia have extremely high levels of ghrelin (the hunger hormone that tells the brain when it is time to eat) in theirblood. The high levels of ghrelin suggests that their bodies are trying to desperately switch the hunger aspect on, however, that hungers call is being suppressed,ignored, or overridden. Nevertheless, one small single-blind study found that intravenous administration of ghrelin to anorexia nervosa patients increased food intake by 12-36%over the trial period.
Anorexia nervosa has many complicated implications and may be thought of as a lifelong illness that may never be truly cured, but only managed overtime. Anorexia nervosa is characterized by low body weight, inappropriate eating habits and obsession with having a thin figure. Individuals suffering from it may alsopractice repetitive weighing, measuring, and mirror gazing, alongside other obsessive actions to make sure they are still thin, a common practice known as "body checking".
