WebMar 25, 2010 · In patients with obesity, adipose tissue is characterized by low-grade inflammation and increased secretion of several cytokines. 1 Tumor necrosis factor α (TNF-α) and interleukin-6 may be most... Fat necrosis is the pattern of damage associated with the destruction of adipose tissue by trauma, hypoxia, or lipase digestion (e.g. pancreatitis). In the classic case of fat necrosis in severe acute pancreatitis, the necrosis arises because adipocytes in the peritoneum are broken and digested by inappropriately activated pancreatic enzymes. Stored triglycerides in the adipocytes are released and split by pancreatic lipases into fatty acids and glycerol molecules. The resultant fatty acids reac…
