When discussing liposuction/BBL (or any body contouring for that matter) in the post partum/peri-natal/breast feeding period, the question is less the danger to the feeding child (most medication will clear in a few days) and rather the changes that your body is going through secondary to hormonal fluctuations. 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. As always, discuss your concerns with a board certified plastic surgeon (ABPS).
