Eating disorders and substance abuse
Anorexia nervosa
There are 2 types of anorexia nervosa, the restricting type who simply
restrict their caloric intake and the binge eating purging type who purge the
food they eat through vomiting and laxatives.
Bulimia nervosa
There are 2 types of bulimia, the purging type who consume too many
calories and then purge them and the non-purging type who do not purge.
Bulimic people tend to overeat and are comforted by eating. This behavior
appears to be about losing control through eating and gaining control
through purging. They also tend to be impulsive about shopping and sex.
Bulimic people tend to maintain a normal body weight
Binge eating
Associated with obesity
No purging behavior
Pica
Eating non-edible items
Rumination
This is where you consume a normal amount of food, vomit it back up, and
then eat it again.
Pro ana/pro mia refers to subcultures that view anorexia and bulimia in a positive
light.
Statistics
55% of people experiencing an eating disorder will also experience a
substance abuse “concern”
12-18 percent of people with anorexia nervosa will experience s substance
abuse “concern”
30-37 of bulimics will experience a substance abuse “concern”
Anorexia nervosa affects women more than men (90-95%)
Anorexia is strongly associated with bulimic symptomatology. That is,
anorexia and bulimia share some of the same symptoms.
Both disorders are characterized by a desire to get rid of food after eating.
People with anorexia are more likely to use legal drugs as opposed to illegal
drugs. They are not big risk takers.
Bulimic men are more likely to be uncomfortable with their sexualities.
