Adequate nutrition status important for bone mineral density improvement in a patient with anorexia nervosa
Abstract
Low bone mineral density (BMD) is one of the most frequent complications of anorexia nervosa (AN). We report the clinical outcomes of a female patient with severe AN, whose chest had become deformed due to thoracic fracture. Lumbar BMD was 0.358 g/cm2 (T-score = -6.3), and total hip BMD was 0.411 g/cm2 (T-score = -4.4). Active vitamin D increased these parameters by 81.0% and 57.4%, respectively, but a drop in her nutrition status afterward resulted in a sharp decrease in BMD values. These findings suggest that adequate nutrient intake is essential for effective osteoporosis treatment in patients with AN.
How strong is the evidence?
Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
