Pregnancy and subsequent breast-feeding can have a dramatic impact on the size and shape of a woman’s breasts. During pregnancy, the breasts increase in size in response to a changing hormonal environment. This phenomena is further accentuated by breast-feeding, as the glanduler tissue enlarges during lactation. To accommodate this increased breast volume, the skin envelope has to stretch as well. Once the process of lactation is completed, the glanduler tissue shrinks, and the breast decreases in size. This loss of volume is often accompanied by the development of breast sag because of decreased breast volume in the presence of stretched skin.

The response of the breast to pregnancy varies from patient to patient, and depends on a variety of factors. These include the starting size of the breast, the length of time spent breast- feeding, and the biologic tendency for the breast skin to stretch during pregnancy.
Depending upon the degree of sag that is present, a multitude of surgical options exist to treat this problem. Every patient’s anatomic starting point and aesthetic goals may be different, and because of this, treatment plans need to be individualized.
