How long after having a C-Section do you have to wait before considering having a procedure such as Smart Lipo performed?

Adequate time for your tummy to shrink down is usually 3-6 months. Back and flanks may be sooner if weight loss has stabilized. If you are also breast feeding, you should wait until finished.An exam and consultation with a plastic surgeon is recommended to discuss your options and expectations. 

Thank you for your question. Since you had a recent pregnancy, I would recommend to wait a minimum of 6 months (for breastfeeding, 9 months from the time you stop producing milk). If you are planning on having more children, it is best to wait until after your pregnancies to consider this procedure. I also recommend being at your ideal weight for best results.

Stability is the goal. It is always best to exhibit restraint in the post-partum period. This is due to the fact that your body is changing dramatically during this period. The hormonal fluctuation can alter size and shape widely during the immediate post-partum period and can continue through the period of nursing. Body contouring during this period is the equivalent of hitting a moving target.
The optimal candidate for surgery has reached a healthy stable weight. In the setting of a recent pregnancy and delivery this stable weight can take some time to reach. A general rule of thumb is at least 6-9 months post-partum. If you choose to breast-feed through the first year of life you should allow at least three months following the discontinuation of breast-feeding before considering any procedures.
While there may be variations in the recommendations from one physician to another, the goal is the same...stability. Thus a delay of 9 months or 3 months post cessation of breast feeding (whichever is longer...will ensure that you have reached a plateau).
As always, discuss your concerns with a board certified plastic surgeon (ABPS).
