Eating disorders are not just about food, weight, vanity or willpower, but are serious and potentially life-threatening mental disorders. Most eating disorders occur when a person has distortions in thoughts and emotions relating to body image, leading to marked changes in eating or exercise behaviors that interfere with the person’s life.
The median age of onset for eating disorders ranges from 18 to 20 years (50% have onset before these ages). A high proportion of people with eating disorders also have another mental disorder, particularly anxiety, mood or substance use disorders. However, less than one-third of people with eating disorders received treatment for a mental health problem in the past 12 months. Eating disorders have the highest mortality rate of any mental illness.
