Biomedical Variables in the Eating Disorders*

Abstract

Anorexia nervosa and bulimia nervosa are complex psychosomatic illnesses for which there may be significant biomedical diatheses and sequelae. This paper reviews these biomedical variables, focusing on the medical and nutritional assessment and management of patients with eating disorders and the medical complications that arise in these patients. The paper then examines the relationship between medical illness and eating disorders, including the medical misdiagnoses often given to these patients and the way in which a chronic medical condition such as diabetes mellitus predisposes a patient to an eating disorder. The relationship between eating disorders and pregnancy is also discussed. Through an understanding of these biomedical issues, iatrogenesis can be prevented and treatment can be improved.
