Eating disorders are among the most frequently seen chronic illnesses found in adolescent females. In this paper, we discuss school-based prevention and intervention efforts that seek to reduce the impact of this serious illness. School counselors play a key role in the prevention of eating disorders and can provide support even when not directly involved in psychological or medical treatment. Because of their ability to play a leadership role in school-based prevention of eating disorders, school counselors are essential in facilitating a collaborative approach to the prevention of and intervention in eating disorders and their associated risk factors.
