Adipose- Driven Chronic Inflammation and Dysregulated Healing

Visceral adipose tissue functions as an active endokrine organ that sekres excess pro- inflatory cytokines, including tumor necrosis factor- alpha (TNF- α) and interleukin- 6 (IL- 6).

Te contenship beween obesity and periferal neuropaty extends beyond traditional hyperglycemic damage. Mounting providete indicates that obesity and metabolic syndrome are consistent risk factors for neuropaty, even in the absence of overt considetes.
