Eating disorders and bone.

Low bone mineral density (BMD) is a frequent and often-overlooked consequence of eating disorders, in particular anorexia nervosa and eating disorders associated with the female athlete triad. The causes of low BMD are multifactorial and include low peak bone mass accrual, accelerated bone resorption, and changes in bone microarchitecture. Early diagnosis and interventions focused on nutritional rehabilitation and weight gain reduce the risk of further BMD deficits and fractures.
