The authors assessed the nutritional status of 60 morbidly obese patients by determining body composition, using multiple isotope dilution at 13.6 +/- 0.4 months following operation. Body weight was followed for an additional 12.3 +/- 0.8 months. Twenty-four patients lost more than 25% of their preoperative weight and were within 30% of ideal weight (a "good" result). At 1 year they had lost 41.4 +/- 1.8% of preoperative weight and the body mass index (BMI) decreased from 46.7 +/- 1.2 to 27.0 +/- 0.6 kg/m2. Despite rapid weight loss, malnutrition did not develop and their body composition became indistinguishable from that of normally nourished volunteers. Twenty-nine patients had a "satisfactory" result with more than 25% weight loss but were not within 30% of ideal. Their weight decreased by 34.8 +/- 1.0% as their BMI decreased from 55.4 +/- 1.2 to 36.0 +/- 0.8 kg/m2. Seven patients lost less than 25% of their preoperative weight (an "unsatisfactory" result). Malnutrition did not develop in any patient. In the authors' experience, in contrast to other weight reducing operations, vertical banded gastroplasty (VBG) results in rapid weight loss without the concomitant development of malnutrition even in patients who return to normal weight.
