Patient-Friendly Explanation

Omental fat resection is a surgical procedure that removes the omentum, a fatty apron of tissue that hangs inside the abdomen. Unlike cosmetic liposuction, this procedure targets deep visceral fat that surrounds the internal organs and is strongly linked to metabolic health problems such as diabetes and heart disease.

Clinical Definition

Omental fat resection, or omentectomy, is the surgical removal of the greater omentum, a visceral adipose depot in the peritoneal cavity. Unlike subcutaneous fat, omental adipose tissue is highly metabolically active, secreting pro-inflammatory adipokines and free fatty acids directly into the portal circulation. Clinical studies suggest that omentectomy combined with bariatric surgery may yield additional improvements in insulin sensitivity and inflammatory markers beyond weight loss alone.

Why It Matters

Visceral fat is the most dangerous type of body fat for metabolic health. Understanding procedures that specifically target this fat depot helps patients appreciate the difference between cosmetic and medically indicated interventions available through NuLifeCare Singapore weight management programme.
