What is Bulimia 

Bulimia nervosa is a disorder that involves binge eating and then purging through self-induced vomiting or the use of laxatives, diuretics or diet pills. Some people with bulimia purge after a binge through excessive exercise or by fasting for days.  

This binge and purge cycle can quickly become a routine that is difficult to break. People with bulimia tend to know their behavior is problematic and become secretive to avoid being discovered. They may spend more time alone than usual and sometimes go through the binge/purge cycle several times a day. 

Physical health complications from bulimia can range from a sore throat and swollen glands in the neck and jaw area to dental issues, such as worn tooth enamel, decaying teeth, acid reflux, gastrointestinal problems, electrolyte imbalances and changes in heart rate. 

Mental health complications of bulimia can be just as devastating as the physical ones. Relationships with family and friends often suffer as the affected person avoids eating with others or resists help from others. Kids with bulimia often feel isolated and depressed, and in some cases my consider suicide, which is the leading cause of death in people with eating disorders. 

What causes bulimia? 

Eating disorders do not have a single cause. They can develop from a combination of biological, psychological and social factors. Genetics and a family history of eating disorders or mood disorders can increase risk. Psychological factors, including perfectionism, low self-esteem, depression, anxiety and difficulty coping with intense emotions may be contributors. 

Who gets bulimia? 

Bulimia tends to affect children and teens, though it can begin at any age and often continues into adulthood. Children and teens with bulimia are especially concerned with how others see them and may feel emotionally insecure or lack confidence. The individual may feel like they live behind a facade—competent and attractive on the outside but inadequate underneath. Dieting often begins as a way to feel better about oneself and to gain approval from others.   

People with bulimia often use food to cope with stress and emotional difficulties. This can lead to unusual eating patterns and an inability to appropriately respond to hunger. People with bulimia usually maintain close-to-normal weights and often go through their binges and purges in private, making the condition difficult to detect.
