Eating Concerns and Body Image

Bulimia

What is bulimia?

Although the literal meaning of bulimia is "hunger like an ox," bulimia nervosa (usually referred to simply as bulimia) is a condition characterized by recurrent episodes of binge eating that may have little or nothing to do with actual physiological hunger. These episodes of bingeing are then followed by recurrent compensatory behaviors intended to prevent weight gain.

A formal diagnosis of bulimia is made when someone:

  • Engages in repeated episodes of binge eating, characterized by

    • Eating in a discrete amount of time (e.g within any 2-hour period), an amount of food that is definitely larger than most people would eat during a similar period of time and under similar circumstances

    • A sense of lack of control; that the person cannot stop eating or control what or how much they are eating

  • Engages repeatedly in inappropriate compensatory behavior designed to prevent weight gain, such as self-induced vomiting; misuse of laxatives, diuretics, enemas, or other medications; fasting, or excessive exercise

  • Engages in the binge eating and inappropriate compensatory behaviors on average, at least once a week for three months

  • Experiences that self-evaluation is unduly influenced by body shape or weight

  • Does not experience these disturbances exclusively during episodes of anorexia nervosa

Bulimia can also present as two different sub-types. Many people with bulimia tend towards the purging type, where they regularly engage in self-induced vomiting, or the misuse of laxatives, diuretics, or enemas. Others may use inappropriate compensatory behaviors such as fasting or excessive exercise, but will not regularly engage in vomiting, laxatives, diuretics, or enemas.

Someone might meet all of the diagnostic criteria for bulimia, or he or she might meet just a few. What's most important is getting expert help as soon as possible in order to prevent health risks and allow them to feel better. According to the Mayo Clinic, bulimia may cause a host of serious and even life-threatening complications. The specific complications someone experiences may be related to his or her choice of purging method, such as overexercise or laxative abuse, and how severe their condition is. 

What are the physiological and psychological complications of bulimia?

  • Death

  • Anemia

  • Heart problems, such as abnormal heart rhythms and heart failure

  • Tooth decay

  • Amenorrhea (In females): As the body registers too great a caloric deficit, estrogen levels drop and menstruation ceases, increasing the risk for erosion of bone density (osteopenia, osteoporosis) and infertility

  • For males, undernutrition and weight loss can lead to changes in testosterone levels, also resulting in weaker bones and increased risk for fractures.

  • Gastrointestinal problems, such as constipation, bloating or nausea. May also include pre-cancerous changes to the esophagus (Barrett's Esophagus), as well as irritation of the stomach, salivary glands, and throat from persistant vomiting

  • Electrolyte abnormalities, such as low blood potassium, sodium and chloride, as well as dehydration from repeated vomiting.

  • Increased susceptibility to depression and anxiety, as well as an increased risk of suicidality 

Why would anyone DO this to themselves OR Why can't people with eating disorders just STOP?

It can be difficult to understand why anyone would repeatedly engage in a behavior that is ultimately harmful, but it's important to remember that eating and exercise disorders are, first and foremost, an attempt at a solution.

Eating disorders often begin with a sense of dissatisfaction that is perceived to be about the body. People start to diet or exercise, never intending or anticipating that they will develop a serious problem. As they engage in the dieting and exercise behaviors, however, and particularly if their efforts are praised or reinforced by other people, the changes in behavior and changes in body size and shape can begin to take on powerful psychological functions. People may find that the disorder provides them with a sense of control, self-esteem, identity, power or safety that felt lacking for them previously. Suddenly, they find that the choice of what to have for breakfast, or whether or not to exercise, is emotionally "loaded" out of all proportion to rationality, and because of that, it becomes enormously difficult to challenge the disordered behaviors, even if they know the consequences are negative.

For people dealing with bulimia, the experience is further complicated by the fact that they alternate between restrictive eating (which may feel good emotionally, but which becomes impossible to tolerate physically), and bingeing (which is emotionally distressing, but physiologically and psychologically driven). Purging, also, can gain a lot of psychological momentum as a perceived means to control size and shape, and as a behavior that can manage emotions. And unfortunately, the more that someone purges or restricts their eating, the more likely it becomes that they will eventually binge. If they respond with more restriction or purging, the cycle starts all over again. Choices about eating, exercise, or purging that once felt voluntary quickly become obligatory. That eating disorders take on a life of their own psychologically, is strongly reinforced by genetic susceptibilities that can heighten an individual's response in terms of brain chemistry, metabolism, and other important physiological processes. 

Denial

In a culture that glorifies body types radically at odds with physiological health, and that normalizes extremes of behavior with dieting and exercise, it can be difficult for someone with an eating disorder to believe that they have a problem with food, exercise, or weight. Even if he or she is able to acknowledge some concern, the fear of losing what might feel like their primary source of safety or self-esteem is often powerful enough to make them want to defend or preserve this way of coping.

Dan Reiff, MPH RD, and co-author of Eating Disorders: Nutrition Therapy in the Recovery Process, uses an analogy he calls "The Helicopter Story." In it, he likens the ambivalence of someone considering eating disorder recovery to a person, unable to swim, who has been stranded in the middle of the ocean with only a life-jacket to keep them afloat. Rescue by helicopter will prevent them from ultimately drowning or dying of hypothermia, but the helicopter team tells the swimmer that he or she will need to give up their life-jacket in order to be pulled on board. It's a daunting prospect, and it's also the reason why people with eating disorders need time and lots of expert support in order to give up their behaviors and recover completely. 

What is the role of genetics and biology?

It is now becoming clear that genetics and biological predisposition play a critical, though not exclusive role in the development of an eating disorder. Studies of people with anorexia and bulimia have found links to specific chromosomes, and a 2006 study led by the University of North Carolina, Chapel Hill, estimated that 56% of the responsibility for developing anorexia nervosa is determined genetically. Other studies have examined variations in serotonin and dopamine receptors in patients with anorexia and bulimia which could serve to reinforce eating disorder symptoms like food restriction. 

What is the significance of biological predisposition for people with eating disorders?

Firstly, it can lessen some of the shame and blaming that goes on when someone develops an eating disorder. Too often, people with eating disorders blame themselves for becoming preoccupied with food and their bodies, not realizing the extent to which these obsessions can be driven by biological susceptibilities. People can be much more compassionate with themselves when they understand that-even though there may have been times when they've consciously chosen to use a disordered behavior in order to cope-they didn't choose the disorder itself. Understanding the biological contribution may also allow some people to feel less shame about utilizing psychiatric medications like antidepressants or anti-anxiety drugs as part of their recovery. 

Does this mean that socio-cultural factors aren't important in the development of an eating disorder?

Not at all. Plenty of people have variable neurotransmitter levels and do not struggle with eating or body image, and many other people with eating disorders have no corresponding predisposition. Even for people with a predisposition, it is the environment in which they live that can mitigate or promote the expression of their genetic tendencies. This is one of the reasons that it remains critical to address the "thinness culture." Another is that dieting-with its potential for malnourishment and disruption of brain chemistry-can contribute to an existing problem in susceptible individuals, or create a completely new one to deal with. In fact, dieting has been called " a necessary, but not sufficient condition for the development of an eating disorder." When it comes to understanding and treating eating disorders, it's important to think in terms of both nature AND nurture.

Is recovery possible?

When medical support, nutrition work, and psychotherapy are utilized, recovery is completely possible for individuals with anorexia. Chances for complete recovery are highest when people receive early, expert treatment at the right level of intensity.
