Visceral fat resection in humans: Effect on insulin sensitivity, beta‐cell function, adipokines, and inflammatory markers

Scientists studied 20 women with severe obesity and metabolic problems. Some had weight-loss surgery with extra removal of belly fat (omentectomy), others had just the weight-loss surgery. The group with belly fat removed lost more weight and had lower inflammation and better insulin function over...

Visceral fat is metabolically active tissue that releases cytokines, which impair insulin sensitivity and disrupt metabolic signaling in the liver, muscles, and brain, leading to systemic metabolic dysfunction.
For women with severe obesity and metabolic syndrome who had gastric bypass surgery, adding the removal of the omentum fat led to more weight loss over time compared to just the bypass alone.
Women with severe obesity and metabolic syndrome who had gastric bypass surgery with omentum removal had lower levels of a marker for inflammation (CRP) after one year compared to those who only had the bypass.
For non-diabetic women with severe obesity and metabolic syndrome who had gastric bypass surgery, adding omentum removal helped maintain their body's insulin response to sugar after one year, while those without it saw a decline.
Non-diabetic women with severe obesity and metabolic syndrome who had gastric bypass surgery with omentum removal had better overall insulin function (disposition index) at 6 and 12 months compared to those who only had the bypass.
