Nutritional Assessment in Obese Patients
As the prevalence of obesity has risen, clinicians must evaluate nutritional status across a range of patient obesity levels and in varied clinical settings. Assessment of the nutritional status of obese patients may be challenging but follows the same schema as for undernourished patients. Patients who undergo bariatric surgery are cared for by multiple nutrition professionals at varied times relative to surgery. The early nutritional assessment evaluates the suitability for surgery and needed lifestyle modifications including dietary, nutritional supplement, and physical activity behaviors. If patients have a surgical complication, they may require a short course of parenteral nutrition that will require assessment of nutrient intake requirements. If patients fail to thrive, most typically at later times after malabsorptive surgical procedures, assessment for micronutrient deficiencies may also be indicated.
