Changes in adiposity measures following surgery

Before surgery 1 month post-RYGB 6 month post-RYGB 24 month post-RYGB
BMI (kg/m2) 47.5 ± 0.9 42.8 ± 0.9 33.9 ± 1.1 30.9 ± 2.1
FAT (kg) 70.1 ± 2.2 61.4 ± 2 40.3 ± 2.5 34.2 ± 5.6
VAT (cm3) 4,500 ± 460 3,750 ± 390 2,320 ± 310 1,630 ± 710
SAT (cm3) 13,580 ± 430 12,700 ± 550 8,750 ± 490 6,900 ± 1,080

Body fat mass (BMI), total adipose tissue mass (FAT), and abdominal visceral (VAT), and subcutaneous (SAT) adipose tissue volumes were measured as described in Methods and Procedures section at 0 (before surgery), and 1, 6 (n = 20), and 24 (n = 10) months following Roux-en-y gastric bypass (RYGB) surgery. Significant decreases in adiposity were observed at all times following surgery (P < 0.000 compared to the baseline measure).
