Anorexia Facts and Statistics


Anorexia Nervosa is the most deadly of all mental illnesses. It is a type of eating disorder that is, unfortunately, becoming increasingly common in the US. We’ve prepared some anorexia facts and statistics for you to become more informed about what’s happening in your family.


Anorexia Nervosa: An Overview

The first time the term “anorexia nervosa” was used, was in 1873 by Dr. William Gull. He was one of the first to study and treat this eating disorder in a medical way. In the past 100 years, during the 20th and 21st centuries, anorexia has become much more common.

In short, anorexia nervosa is the name for a mental disorder that describes an individual who severely restricts his or her food intake. People with anorexia have an extreme desire to be thin and lose weight. They often see themselves as fat, and therefore unattractive, despite whatever the mirror or the scale says. Even when the person is visibly underweight and quite frail, he or she might not admit to a problem. Misperception and self-harming weight-loss behaviors are what characterize this mental illness.

Sometimes people who suffer from anorexia nervosa also engage in purging behaviors. These might include forcing oneself to throw up, using laxatives, or extreme exercise. Purging may happen on occasion, however, if it’s a regular occurrence, bulimia nervosa may be a more accurate diagnosis. Purging is the focus in cases of bulimia, and severe-food restriction is the focus in anorexia cases.


  • An estimated .9% of all American women are estimated to suffer from anorexia at some point in their lives. Girls and younger women are the most vulnerable for developing bulimia.
  • Only about .3% of American men will ever experience anorexia in their lifetime. Gay and bisexual men are at greater risk than straight men. This might be due to higher beauty standards and more pressure to look good in the gay community.
  • Bulimia nervosa has a mortality rate of 6%. This means that of all anorexia cases, about 6% will die due to the disease. This figure is based on a meta-analysis of 42 scientific studies over the past 50 years.

What makes Anorexia so dangerous?

This mental illness is so dangerous because the individual is literally putting their body through starvation conditions. Every organ system is at risk for damage in cases of anorexia. The body is simply not receiving the nutrients and minerals necessary for good health. These are the medical complications that develop due to anorexia:

  • 50% of those with anorexia will develop osteoporosis. This refers to when the bones weaken and get thinner.
  • Amennorrhea. This is a term for when a woman’s menstrual cycle stops because of weight loss.
  • Brittle hair and nails.
  • Yellow, unhealthy appearing skin.
  • Lanugo. This is the scientific name for a special type of hair that grows on the human body during conditions of starvation. It’s a soft, fine type of hair that grows all over the face and body. Scientists believe this is the body’s attempt to stay warm when there’s not enough fat to insulate us.
  • Cold intolerance or even hypothermia, which is a lowered body temperature.
  • Low blood pressure. This can contribute to fainting spells, and weakness.
  • Irregular and rapid heartbeat
  • Abdominal distension. This refers to a big, swollen rounded belly. It is important to know that the belly is not fat, it’s just swollen.
  • Hair loss
  • Halitosis, a.k.a. bad breath. This may be due to vomiting, malnutrition, or ketosis. Ketosis happens when the body has no carbohydrate intake and starts to produce excessive acetone which can be smelled on the breath and skin. Yes acetone, as in nail polish remover.
  • Orange colored feet
  • Chronic fatigue
  • Muscle pain and tension

Comorbidity: co-occurring mental illnesses

Oftentimes anorexia is made worse, and potentially more fatal, by co-occurring mental illnesses. In most cases, those with anorexia will also have a mood disorder, personality disorder, underlying anxiety, and very commonly some form of self-harming disorder.
