Body compositional changes during rapid weight loss and after weight stabilization were prospectively studied in morbidly obese patients undergoing gastroplasty operations. Body composition was studied preoperatively and 6 and 24 months postoperatively in 23 patients by use of a total body counter (40K) and an isotope dilution technique. The mean fat mass, cell mass, and intracellular water (ICW) decreased during the first 6 months (p less than 0.001) and remained unchanged at the 24-month test. However, the mean liters of extracellular water (ECW) did not change. Consequently, the ECW/ICW ratio, high in states of malnutrition, rose above postoperative levels. A strong correlation was found between decreases in cell mass and increases in the ECW/ICW ratio.
