Obese Abdomen with Visceral Fat, cross section
Visceral fat is found deep inside your abdomen, surrounding your vital organs. It's different from subcutaneous fat, the kind that's just under your skin. Too much visceral fat physically crowds your organs and your diaphragm. This can restrict your organs' blood supply and make it difficult for you to breathe deeply. Visceral fat secretes dangerous hormones and inflammatory chemicals. The blood that circulates through visceral fat goes directly into your liver through the portal vein. That means the substances your visceral fat produces all pour directly into your liver and into your bloodstream. Scientists think this may have important, and damaging, consequences, such as creating systemic inflammation.
