A relatively increased amount of total body water and a relative increase in extracellular water will result in an underestimation of the percentage of body fat and an overestimation of fat-free mass in the morbid obesity state. A different body build disposition (mainly in those with severe abdominal obesity) will result in an overestimation of the percentage of body fat. New equations are needed to validate bioelectrical impedance analysis in morbidly obese patients.

Based on these observation: 1) patients of class II and III obesity present peripheral resistance to hyperinsulinemia without hyperglycemia; 2) RYGBP is able to reduce anthropometric measurements and body composition in a similar way for patients who have, or have not, MS; 3) there is rapid normalization of biochemistry of carbohydrates and lipids; 4) patients with previous MS lose the criteria needed for this diagnosis after 6 postoperative months.
