No Thinspiration

NEW YORK (Reuters Health) - Many women may fail to recognize bulimia symptoms in themselves, particularly if they don’t go to the extremes of self-induced vomiting, new research suggests.

In a study of 158 women with bulimia-type eating disorders, Australian researchers found that nearly half did not acknowledge a problem with their eating. This was particularly true of those who did not vomit to control their weight.

Bulimia is widely known as a “binge-purge” eating disorder, in which a person goes through cycles of excessive eating followed by purging – through either vomiting or abusing laxatives and diuretics.

But there are also non-purging forms of bulimia, where tactics like excessive exercise or strict dieting are used to counter binge-eating episodes.

Still other people have certain symptoms of bulimia but fall short of all the criteria used to diagnose the disorder; they may fall into the category of “eating disorder not otherwise specified,” or EDNOS.

The new study, published in the International Journal of Eating Disorders, focused on women with “bulimic-type” eating disorders. This included those with purging or non-purging bulimia, as well as women with EDNOS. Some women in the latter group were diagnosed with binge-eating disorder, which involves excessive eating but no purging to compensate]

Young sufferers of anorexia and bulimia who try to hide their eating problems from their parents and doctors are turning to a growing number of internet chat rooms dedicated to perpetuating their illness.

A pilot study released this week of US eating disorder patients aged between 10 and 22 showed that up to a third learn new weight loss or purging methods from websites that promote eating disorders by enabling users to share tips, such as what drugs induce vomiting and what internet sites sell them.

But the study - published in the American Academy of Pediatrics’ journal Pediatrics - found that eating disorder sufferers were also learning new high-risk ways to lose weight from each other on websites aimed at helping them recover.

The survey by researchers from Stanford University School of Medicine and Lucile Packard Children’s Hospital at Stanford showed a third of patients also visited pro-recovery sites and half of them learnt new weight loss and purging methods.

“Parents and physicians need to realise that the internet is essentially an unmonitored media forum,” said Rebecka Peebles, Packard Children’s adolescent medicine and eating disorder specialist and an author of the study.

Bulimia nervosa, more commonly known as bulimia, is an eating disorder. It is a psychological condition in which the subject engages in recurrent binge eating followed by an intentional purging. This purging is done in order to compensate for the excessive intake of the food and to prevent weight gain. Purging typically takes the form of vomiting; inappropriate use of laxatives, enemas, diuretics or other medication; excessive physical exercise, or fasting.

Anorexia nervosa is a psychiatric diagnosis that describes an eating disorder characterized by low body weight and body image distortion. Individuals with anorexia often control body weight by voluntary starvation, purging, vomiting, excessive exercise, or other weight control measures, such as diet pills or diuretic drugs. It primarily affects young adolescent girls in the Western world and has one of the highest mortality rates of any psychiatric condition, with approximately 10% of people diagnosed with the condition eventually dying due to related factors.[1] Anorexia nervosa is a complex condition, involving psychological, neurobiological, and sociological components.[2]

Anorexia is a life threatening condition that can put a serious strain on many of the body’s organs and physiological resources. A recent review of the scientific literature outlined a number of reliable findings in this area.[3] Anorexia puts a particular strain on the structure and function of the heart and cardiovascular system, with slow heart rate (bradycardia) and elongation of the QT interval seen early on. People with anorexia typically have a disturbed electrolyte imbalance, particularly low levels of phosphate which has been linked to heart failure, muscle weakness, immune dysfunction, and ultimately, death. Those who develop anorexia before adulthood may suffer stunted growth and subsequent low levels of essential hormones (including sex hormones) and chronically increased cortisol levels. Osteoporosis can also develop as a result of anorexia in 38-50% of cases,[4] as poor nutrition lead to the retarded growth of essential bone structure and low bone mineral density.

Furthermore, changes in brain structure and function are early signs of the condition. Enlargement of the ventricles of the brain is thought to be associated with starvation, and is partially reversed when normal weight is maintained.[5] Anorexia is also linked to reduced blood flow in the temporal lobes, although as this finding does not correlate with current weight, it is possible that it is a risk trait, rather than an effect of starvation.[6]
