Cellulite Defined
Cellulite can be loosely defined as the dimpled or bumpy contour that the skin assumes because of the irregular distribution of fat beneath the skin surface. The cause for this appearance change is complex and not completely scientifically understood. As patients store fat, each individual fat cell becomes larger. Fat cells are controlled primarily by genetic predisposition and certain clones in particular locations (hips, thighs, posterior arms, buttock and abdomen) are controlled by estrogen receptors on the fat level membrane. In females, these deposits probably represent evolutionary development to insure adequate resources to nurture and support children and therefore these cells are not very easily affected by diet or exercise. Even women marathon runners who have ceased having their menstrual periods may still have areas of cellulite. |

Why?
Fat globules are divided into segments similar to partitions in a down comforter wherein the baffles prevent all the material from shifting from one end to the other, insuring a more even distribution of the insulating material. In the skin, divider cords run from the lower part of the supporting layer of the skin, down through the fat layer and mesh into the upper layer of the muscle. The cords are made up on collagen and blood vessels.
It is believed that over time the cords may shorten and very slightly compress the blood supply and slightly compromise blood flow. The enlargement of the fat globules between the cords (possibly those clones with the greatest estrogenic sensitivity, again an inherited characteristic) contributes to the increased pressure on the tissue and creates a vicious cycle of injury by reducing the metabolism of the collagen/fibrous cord cells.
