If you're at your goal weight when you have surgery, you are more likely to have a stable long-term result — which is what we want.
If you want a breast reduction but just had a baby, there are several important things to consider before scheduling surgery.
During and after pregnancy, your breasts go through significant changes — engorgement, milk production, increased blood supply. All of that needs to stop and resolve before surgery. Operating on breasts that are still in that postpartum state increases complications and makes it harder to get a predictable, long-lasting result.
If you breastfed, waiting is especially important for two reasons:
Breastfeeding introduces mouth bacteria into the ductal system of the breast. If those bacteria are still present at the time of surgery, it can change your complication profile — you may see more serious infections rather than the typical skin bacteria surgeons normally encounter.
If you're cutting through breast tissue that is still lactating, you can get milk leaks — which are a nightmare to manage. They can cause horrible healing problems and significant complications.
Weight gain during pregnancy is normal, but your surgery results will be more stable and predictable if you're at or near your long-term goal weight when you have the procedure. Significant weight changes after a breast reduction can alter your results — so giving your body time to settle after pregnancy leads to a better long-term outcome.
A breast reduction after pregnancy can be a life-changing procedure, but timing matters. Let your body fully recover from pregnancy and breastfeeding, reach a stable weight, and then schedule your consultation. The result will be well worth the wait.
