"Eating disorder" is a fairly benign name for a range of behaviors that can have devastating consequences, causing permanent, even life-threatening, damage to multiple organs. These disorders can also compromise mental health.
That's why specialists underscore the need for early intervention by patients, family, friends or physicians before damage becomes irreversible.
