I recommend discussing the timeline with your surgeon. Keep in mind, for best results with Coolsculpting, a combination approach is needed. I recommend adding radiofrequency treatments like Vanquish, Venus Legacy, Exilis Ultra for skin tightening and with Z wave/Cellutone for skin smoothing. However, a Vaser with ThermiRF procedure is the best combination for a toned result, but requires more downtime. See an expert. Best, Dr. Emer
I would recommend that you discuss your plan, to have CoolSculpting a week before your tubal ligation, with the surgeon performing your tubal ligation. While I do not believe that CoolSculpting should affect results of your tubal ligation, and vice versa, if the area of the surgery is close enough to the area that is treated with CoolSculpting there could be an issue with performing the surgery.
