The reliability of bioelectrical impedance analysis for measuring changes in the body composition of patients with anorexia nervosa

Article Abstract:

Skinfold calipers are a better method than bioelectrical impedance analysis (BIA) for determining changes in the body composition due to anorexia nervosa. BIA is unable to record changes due to hydration differences, and to determine the water distribution in the intracellular and extracellular compartments. BIA uses regression analysis, and the body composition values are adjusted toward the group mean position. Values varying from the mean give wrong estimates of body fatness. Modifications incorporated in BIA, to make it more sensitive to hydration, fail to give satisfactory results.

Pancreatitis causing death in bulimia nervosa

Article Abstract:

A study was carried to increase awareness regarding the similarities between the symptoms of bulimia nervosa and acute pancreatitis, and that the pre-existence of an eating disorder should not distract the physicians from the possibility that pancreatitis may coexist. Any carelessness regarding the possibility of pancreatitis may even lead to death.
