Research on eating disorder treatments indicates that early intervention in eating disorder behaviors (that is, early identification and treatment of an eating disorder) improves the speed of recovery, reduces symptoms to a greater extent, and improves the likelihood of long-term recovery.
For example, when adolescents with anorexia nervosa are given family-based treatment within the first three years of the illness onset, they have a much greater likelihood of recovery. [1, 5, 6, 7].
Early intervention allows for any medical concerns caused by the disorder to be addressed before they are exacerbated by the disorder. It also allows the struggling individual to work on reducing or eliminating eating disordered behaviors; address co-occurring issues like depression, anxiety, or trauma; and then develop a plan to prevent relapse. [1, 2]
While treatment is more effective before the disorder becomes chronic, those struggling with long-standing eating disorders can and do recover. For example, one study showed that those who received treatment within the first 5 years of struggling with bulimia had a recovery rate of 80%. While those who waited more than 15 years after their symptoms began to get treatment, experienced recovery rates closer to 20%. [1, 4]
Regardless of their duration, eating disorders can have both physiological and psychological impacts.
Therefore, adequate treatment addresses the eating disorder symptoms and medical consequences, as well as psychological, biological, interpersonal, and cultural forces that contribute to or maintain the eating disorder. 
Early detection, initial evaluation, and effective treatment are important steps that can help an eating disorder sufferer move into recovery more quickly, preventing the disorder from progressing to a more severe or chronic state. Receiving appropriate treatment is the first step towards recovery.
