If I have fat grafting and I lose weight, will the results of my fat grafting change?
Fat grafting (read more here) is essentially a transplant of fat cells from one part of the body (usually the abdomen or waist) to another part of the body (often the face, breasts, buttocks, hands, or feet (read more here). When the fat is transferred from the donor site to the recipient site, blood vessels in the recipient site grow into the fat grafts so that the fat cells in the graft can live in their new location. This is all to say that the fat transferred in a fat grafting procedure goes on to behave like regular fat elsewhere in the body. If you lose a significant amount of weight after a fat grafting procedure, the volume of your fat graft will decrease. Alternatively, if you gain weight after your fat grafting procedure, your fat graft will increase in volume. For this reason, we recommend that you have fat grafting performed when you are as close to your goal weight as possible. One exception to this recommendation applies to extremely lean individuals that desire a fat graft. It is not unreasonable for people in this situation to gain weight in preparation for a fat grafting procedure so there is enough fat to harvest. At the time of the procedure, fat can be harvested from multiple different sites and concentrated at the recipient site, ideally over-correcting that site. When the individual returns to his or her goal weight after the procedure, their graft will decrease in size, but this will have been accounted for by over-correcting the recipient site with fat from multiple donor areas.
