Feeding the critically ill obese patient: the role of hypocaloric nutrition support.
Obesity and its many metabolic and physiologic comorbidities are becoming more common. Thus, a strategy to approach the nutritional needs of obese critically ill patients is warranted. The adverse effect of obesity on the respiratory system is well established. The obesity may be an inciting event or merely an additional burden in the obese critically ill patient. A strategy of hypocaloric nutrition support avoids the many detrimental effects of overfeeding and has been considered for all critically ill patients. In the obese patient, the strategy addresses the additional problem of the excessive fat store and has the additional benefit of fat reduction while sparing lean body mass. In the patient with normal renal and hepatic function, hypocaloric nutrition support simplifies care and may improve outcome.
