CLEVELAND -- Mary-Kate Olsen's battle with anorexia is sparking a lot of discussion, and many girls who suffer from eating disorders, are often the least likely a parent would suspect, reported NewsChannel5's Tonya Strong.

The Olsen twins are rich, wholesome, and successful, but this profile is actually not out of the ordinary for teen girls diagnosed with the disorder.

Smart kids, kids who are good at many things can suffer from anorexia, and one of the first major symptoms is an obsession with food to the point where it becomes ritualistic, reported Strong.

Measuring every morsel of every meal, exercising excessively and even abusing laxatives are warning signs.

Seventeen-year-old Halle Hagenau said, "If you have really distorted body image, a lot of times you can start hurting yourself in totally unhealthy ways, crazy diets and anorexia and bulimia.”

Hagenau added, “The 'perfect' pictures in popular fashion and teen magazines, don't help either.”

"The media just sort of drilled it in that this is the ideal body image," said 16-year-old Robin Davis.

"They just obsess and ruminate about food and weight, food and weight,” said psychiatrist George Pallotta of MetroHealth Medical Center.

Traditionally, middle and upper class teens are more often affected and family therapy is what's needed to address eating disorders.

Pallotta said, "You need a psychiatrist, a pediatrian, you need a psychologist.”

Long term or residential treatment, such as that sought by Olsen can in some cases be the best solution.
