How Are the Dead Fat Cells Excreted by the Body After Cool Sculpting? Also Do They Cause Fat Emboli?

Once the fat cells are destroyed (dead), the body recognizes that they are no longer needed and a gradual process occurs where the fat cells and fat material is cleared away. The fat cells are degraded by enzymes. The actual fat is transported through the lymphatics, and converted to energy just like the fat that you eat. It is no different than the fat that you consume in a meal. This is a natural process, and your body is already fully equipped to handle the destroyed fat cells and remove them as well as manage the fat that is released. This process is gradual and takes a few weeks to months, so a slow gradual improvement is noted. You may see this as soon as a month but it will continue to improve for up to about 3 months.

Once the fat cells die from Zeltiq's coolsculpting, the macrophages of the immune system consume them and distribute them. As there is no injury to the vascular system with CoolSculpting there isn't a mechanism of which I'm aware that a fat embolus would occur and I am not aware of such a report, unlike when abdominoplasty has been done at the same time as  liposuction.

The body processes the dead fat cells and naturally taken away by your body’s mechanism for removing dead cells. They are eventually processed by the liver and excreted as waste over a span of three months. There is no chance they can cause fat emboli, because the fat cells do not enter the venous or arterial system.
