Teens struggling with eating disorders need go no further than the computer to find support. But all too often, this is the wrong kind of help. "Pro-ana" websites, which are sites promoting anorexia as a lifestyle choice rather than a disorder, have flourished over the past few years. Using a search engine to type in "anorexia," teenagers who are reaching out for a healthy supportive environment may find something very different.

In spite of a ban on pro-ana websites by several large search engines, there are still hundreds that pop up. Offering how-to tips on purging, keys to disguising thinness or passing a weigh in, pro-thin quotes, and numerous images of emaciated models, these sites validate unhealthy behaviors. For teens teetering on the edge of recovery or spiraling downward into dangerous eating behaviors, they may reinforce the idea that it's fine-even desirable-to have an eating disorder.

While pro-ana sites cannot be blamed for causing an eating disorder, there is no question that they may perpetuate problems by appealing on a psychological level. Children and adolescents with anorexia often feel lonely and isolated. Joining a community of like-minded people may fill this void.

For this reason-and many others-it's important to be aware of what Internet sites your children are visiting. If you have concerns, there are computer programs available that allow you to block offensive sites. And it's good to know about some healthy website options available for a child struggling with weight issues, body image concerns, or an eating disorder. Look for websites developed by a psychotherapist who specializes in eating disorders for valuable sources of information about weight management, healthy eating and concerns about body image.
