Effects of Anorexia on Bones and Growth
Whether anorexia occurs during the critical stages of development in adolescents or in young women, one of the major effects of anorexia on the body is a loss of bone calcium. Nearly 90% of women with anorexia experience ostenopenia, or loss of bone calcium, while 40% develop osteoporosis, an advanced and even more serious loss of bone density. Bone loss in women is largely due to low estrogen levels, which are a hormonal effect of anorexia. However, other biological factors of this eating disorder may also contribute to bone loss including:
Early diagnosis and treatment can improve the overall prognosis in an individual with anorexia. Despite most psychiatric medications having little effect on the symptoms that are specific to anorexia, the improvement in associated symptoms (for example, anxiety and depression ) can help anorexia sufferers engage more actively in treatment and otherwise have a powerful, positive effect on the improvement that individuals with anorexia show over time. With appropriate treatment, about half of those affected will make a full recovery. Some people experience a fluctuating pattern of periods of weight gain followed by relapses, while others experience a progressively deteriorating course of the illness over many years, and still others never fully recover. It is estimated that about 20% of people with anorexia remain chronically ill from the condition.
In a November 2009 interview with Women's Wear Daily , model Kate Moss gave a popular thinspirational slogan as her motto: "Nothing tastes as good as skinny feels."  Moss came under widespread criticism—particularly by eating disorder recovery organizations—for endorsing pro-ana. Her agency , Storm , stated: "This was part of a longer answer Kate gave during a wider ranging interview which has unfortunately been taken out of context and misrepresented."  Still, Moss has been known in the fashion world to have helped popularize the " heroin chic " trend, which uses models with disheveled, ultra-skinny, and waif-like body types on the runway.
