Liposuction and Breast Feeding

The easy answer is that it's best to wait until the completion of breast feeding before undergoing elective surgery.  One concern is that medications given to the patient may be passed to the baby through the breast milk.  Another issue is that the mother's body will likely change after she completes breast feeding.  In cases where a mother is still considering elective surgery while breast feeding, it's reasonable to involve the baby's pediatrician in the planning of medications and timing for discarding breast milk.

As liposuction is not a treatment that is designed to improve a life-threatening disorder, it should not be done during breast feeding as the procedure is elective for cosmetic indicaitons and there is no reason to jeopardize your baby's health.
 

In my practice I would delay your liposuction even under local until you had completed your breast feeding. I would not feel it acceptable to do this with any risks to the breast milk. I'm very conservative.
