7 Eating Disorder Facts for Adolescents and Young Adults

Wikipedia describes eating disorders as “mental disorders defined by abnormal eating habits that negatively affect a person’s physical or mental health.” It includes anorexia nervosa, bulimia nervosa, pica, binge eating disorder, and rumination disorder. However, it excludes obesity.

Eating disorders are linked with both genetics and situational factors. Cultural obsession with thinness as evidenced in media and advertising is thought to play a role. Ten times more females than males are affected by some type of eating disorder. In addition, these disorders often develop early in adolescence or young adults.  People who have experienced sexual abuse have a higher risk of developing an eating disorder. The good news is that over 70-percent of people diagnosed with anorexia, 50-percent of those diagnosed with bulimia, and 40-percent or more of those with binge eating disorder will make a full recovery…

 

1. Anorexia Nervosa

People who have anorexia will deliberately restrict their food and caloric intake in order to achieve an abnormally low body weight. If left untreated, this disorder can prove fatal.

This eating disorder affects 0.4-percent of adolescents and young women. However it is estimated that more than 4-percent of all women will struggle with anorexia nervosa over the course of their lifetime.

4. Cognitive Distortions Associated with Anorexia

Distorted thoughts about food, weight, and body image are central to those affected by this disorder. Patients may feel they should be perfect, which gives rise to all or nothing thinking. This in turn gives rise to obsessive perfectionism in regards to attaining the “ideal” body.

Sufferers may also reject the positive in that they see all fats and calories as negative. Anorexics also tend to unfavorably compare themselves to others, label foods as fattening, and catastrophize about weight gain. If they gain a pound, it’s the end of the world and nobody will like them.

5. Physiology and Anorexia

Food is the body’s first choice of fuel. If inadequate nutrients are eaten, then the body breaks down fat stores. Once these are depleted the body begins to break down muscle tissue. This results in the production of ketones, which enter the bloodstream and cross the blood-brain barrier.

When this happens, a person’s ability to think rationally is severely compromised. This is why patients suffering from extreme case of anorexia nervosa are hospitalized and force fed intravenously and with a gastric tube. Their lives are in danger, and psychotherapy will be ineffective until their weight is stabilized and ketones are no longer flooding the brain.

6. Pica

According to Wikipedia, pica “is characterized by an appetite for substances that are largely non-nutritive, such as paper, clay, drywall or paint.” Pica is frequently seen in developmentally challenged individuals who exhibit persistent and compulsive symptoms for more than 4 weeks.

Pica is a common disorder in children with mental disability, brain injuries, or autism.  Approximately 10 to 30-percent of children between 1 and 6-years of age are affected by this disorder.

7. Rumination Disorder

This disorder is characterized by a normal intake of food followed by immediate regurgitation into the mouth and re-chewing of the food. The food is often swallowed again and occasionally spit out. Rumination disorder is most common in infants between the ages of 3 to 12 months and cognitively impaired children.

Rumination disorder may be caused by illness, abuse, stress, or as a means to gain attention.  Rumination disorder can result in weight loss, dehydration, malnutrition, halitosis, tooth decay, indigestion, and chapped lips.
