Obesity and its complications, such as diabetes, have become
a major health problem. Existing treatment options
for obesity are very limited and tend to be associated with
disappointing sustainable effects. Gastric bypass surgery
is considered to be the most effective treatment option
for weight reduction in obese patients with type 2 diabetes
(T2DM).To evaluate reduction in abdominal visceral
fat, 52 T2DM patients with obesity were recruited to measure
the distribution of fat mass by Tanita Body Composition
Analyzer and abdominal fat mass by Quantitative
CT (QCT).The remission rate of T2DM and obesity were
86.5% (45/52) and 67.3% (35/52) respectively.BMI and
fat mass decreased significantly after surgery, while free
fat mass remain stable. Moreover, total visceral fat volume
(TVFV)contributed more fat loss, accompained by
the decline of total abdominal fat volume (TAFV), than
total subcutaneous fat volume(TSFV).Then, TSFV declined
obviously only at 12 months after RYGB.Conclusion:
LRYGB can cause reduction of abdominal visceral
fat, while QCT could assist bariatric surgeon to evaluate
distribution of abdominal visceral fat accurately.
