Breast reduction after childbirth should not be done until at least 3 months following completion of breast feeding, due to the loss of breast volume and body weight , and to ensure that breast milk production has completed. A stable weight for at least 3 months is ideal with no plans to loose further weight. Any weight loss following breast reduction surgery may alter the shape of the breast. A recent study of breast shape with implants following pregnancy has shown that implants do not adversely affect breast shape. Factors such as weight gain, smoking, age of pregnancy, number of pregnancies, and breast size were more important in determining breast shape following pregnancy. I recommend that you control weight gain during pregnancy and support your breasts in a comfortable, well-fitting bra as much as possible. We have seen that diet and exercise and good healthy habits will maintain your body shape through child birth.
