Learn More about Eating Disorders

Eating disorders usually appear during the teen years and early adulthood, although they can appear at any stage in life.  They include serious emotional and physical problems that can have life-threatening consequences if left untreated.

Types of Eating Disorders 1 2

  • Anorexia Nervosa – serious, potentially life-threatening eating disorder characterized by self-starvation, excessive weight loss and often distorted body image. People with anorexia nervosa see themselves as overweight, even when they are dangerously underweight and restrict calorie intake and types of feed eaten.  Some sufferers exercise compulsively, purge by vomiting and laxatives, and/or binge eat.  Approx. 90-95% of anorexia nervosa sufferers are girls and women. Between 0.9-2% of American women and .1-.3% of males will develop anorexia nervosa. It is the third most common chronic disease among young people. In women, suicide is more common in those with anorexia than with any other mental disorder.
  • Bulimia Nervosa – serious, potentially life-threatening eating disorder characterized by a cycle of binge-eating with lack of control followed by  compensating behaviors such as self-induced vomiting, excessive use of laxatives or diuretics, fasting, excessive exercise, or a combination of these behaviors in order to prevent weight gain.  Between 1.1%-4.6% of adolescent and young women and 0.1%-0.5% of young men are affected by it.
  • Binge Eating Disorder (BED) – the most common eating disorder in the U.S. characterized by recurrent episodes of eating in large quantities of food (often quickly to the point of discomfort); feeling of loss of control during the binge; experiencing shame, distress or guilt afterwards; and NOT regularly using unhealthy compensatory measures (e.g., self-induced vomiting, misuse of laxatives, diuretics, or other medications, excessive exercise or fasting) to counter the binge eating. It is a severe, life-threatening and treatable eating disorder. Between 0.2% and 3.5% of females and 0.9% and 2.0% of males will develop it. Often begins in late teens and early 20’s but can occur in younger children and older adults. Approx. 40% of those with BED are male.
  • Other Specified Feeding or Eating Disorder (OSFED) – feeding or eating disorder that causes significant distress or impairment, but does not meet the criteria for another feeding or eating disorder.
  • Avoidant Restrictive Food Intake Disorder (ARFID) – new diagnosis in the DSM5 (previously called “Selective Eating Disorder”). ARFID is similar to anorexia in that both disorders involve limitations in the amount and/or types of food consumed, but unlike anorexia, ARFID does not involve any distress about body shape or size.
  • Unspecified Feeding or Eating Disorder (UFED)  -when symptoms characteristic of a feeding and eating disorder that causes clinically significant distress or impairment in social, occupational or other important areas of functions predominate but do not meet the full criteria for any of the diagnostic class.
  • PICA– Eating Disorder that involves eating items that are not considered food, or having nutritional value, such as hair, paint chips and dirt. Diagnosis is made from the clinical history of a patient.
  • Rumination Disorder Repeated regurgitation of food for a period of at least one month.  Regurgitation may be re-chewed, re-swallowed or spit out. The repeated regurgitation is not due to a medical condition. The behavior does not occur exclusively in the course of anorexia nervosa, bulimia nervosa, BED, or avoidant/restrictive food intake disorder. If occuring in the presence of another mental disorder, it is severe enough to warrant independent clinical attention.
  • Orthorexia Disorder– Orthorexia is not a formal diagnosis in the Diagnostic Statistical Manual but was coined in 1998. It involves a fixation on so called “healthy eating” to the point of being unhealthy causing actual damage to a person’s well being. Some studies show a correlation between orthorexia and obsessive-compulsive disorder.

Body Image

Negative or Distorted Body Image is how people see themselves.  Distorted body image, a/k/a negative body image is the way a person sees themselves which is not based in reality.  Women are more likely than men to suffer from this disorder, although men do too. Your perception of your body starts forming when you are a child with regards to beauty, health, attractiveness, acceptability, etc. Your perception is influenced by others, like your peers, teachers, parents, coaches, for example, as they give you feedback throughout your life. Society, in general, can also influence self perception, such as when the media dictates to young women through print ads that being skinny is attractive.  Personality traits, like perfectionism and self criticism, also negatively impact body image perception.
