After having coolsculpting will taking a laxative speed up the flushing of the dead fat cells?

Taking a laxative after a CoolSculpting procedure will have no effect on the speed of achieving results or disposal of the dead fat cells.  The destroyed fat cells are not excreted but eliminated by cells in the body, called macrophages.  

The dead fat cells
will undergo apoptosis on the normal schedule – there are no external
treatments such as laxatives which will speed up this process. The cells
are metabolized by the body and are excreted by the kidneys through
urination. Staying hydrated – i.e. 8 x 8 ounce glasses of water a day
will maintain healthy kidney function.
