Eating disorders. Guide to medical evaluation and complications.

Eating disorders lead to numerous physical complaints with signs and symptoms affecting nearly every organ system of the body. We review the presentation of a patient with eating disorder to the primary care giver or general psychiatrist, focusing on the physical manifestations of the underlying illness. Specific complications related to laboratory findings, the gastrointestinal tract, and the endocrine system are reviewed. Algorithms for medical evaluation of these patients are also presented.
