What is an eating disorder?
Eating disorders is a broad name for a number of problems we face with food in our society. While many of us slip into overeating or comfort eating at some point, for some the problem goes to life-threatening extremes.
In both anorexia nervosa and bulimia, there is a deep fear of being overweight that leads to an obsession about restricting the number of calories the person is taking in. This leads to an extreme state of starvation, which in turn has a number of effects on the way that the body functions and how hormones are produced.
This is complicated in bulimia, when the person still finds comfort in the feeling of being full but dreads taking on the extra calories. This is when they may induce vomiting, causing long-term problems for their throat and teeth on top of psychological problems.
Common behaviour of someone affected by an eating disorder includes:
- Mentally keeping a balance between calories taken in and calories used up
- Deep-seated feelings of anxiety if they consume a few calories too many
- Self-loathing, depression or panic if they haven’t lost any weight or put a little on, despite their best efforts
Many anorexics and bulimics have researched the issue of diet quite deeply and know the damage they are doing to themselves but are still unable to stop. This just makes the feelings of despair and self-loathing even worse, causing their condition to continue.
Causes of eating disorders
While there is evidence that eating disorders can run in families, it isn’t yet clear how much risk for developing anorexia or bulimia is carried by genes.
The social and psychological factors have been better identified, but they are complicated.
Socially, it doesn’t help that we are sometimes pulled in two directions by the media.
The first way is with images of physical perfection - the man with the perfect six-pack on the cover of a magazine, or a young woman in a bikini. A review of research in 2002 found that women who viewed images of thin models were significantly more dissatisfied with their body images afterwards than women who viewed images of average-size models. This dissatisfaction was higher among younger women and women who already had issues with their body image.
The second way is the encouragement to eat foods packed with calories made up of saturated fat and simple carbohydrates, the two food types most likely to make you put on weight. Another research review in 2009 took international data on children’s television viewing, food advertising and childhood obesity. They found exposure to food advertising was related to childhood obesity, although the strength of the relationship varied from country to country.
Psychologically, at the root of an eating disorder may be a combination of a number of issues, including:
- Distorted body image
- Low self-esteem
- Anxiety for some control
- An expression of deep emotions such as depression or trauma that can’t be put into words
Each person affected by an eating disorder brings their own unique experiences to the problem. For each, the meaning of anorexia or bulimia has aspects that are personal to them.
Treatments for eating disorders
There is limited evidence that some psychiatric drugs can help with anorexia and bulimia, and that some psychotherapy approaches can have some effect.
Cognitive behavioural therapy (CBT) makes a good start to alleviate the issues. For longer term recovery, psychological approaches that look at how the person relates to those around them might have more effect. These could psychotherapy focussing how on interpersonal relationships work and family therapy.
Eating disorders and the family
The effectiveness of family therapy in treating eating disorders has lead to some theories about family environment as a cause. The evidence suggests that while it can make a contribution, family functioning is not enough on its own to set off an eating disorder. It appears that a number of factors need to come together, including obsessive-compulsive disorder like symptoms and depression.
When families are faced with a loved one with an eating disorder, the idea they may have caused it is not only inaccurate but can also lead to feelings of guilt and recriminations that can get in the way of helping the person to recover.
Family members as well as the person with the eating disorder need to focus their energies on:
- Staying with their loved ones
- Keeping resilient and sympathetic
- Working with a team of carers and therapists
Recovering from eating disorders
Recovery can take years and how recovery is defined can be difficult. Even if the person manages to regain and retain a healthy weight, they may still find food and eating to be difficult and emotive issues.
