Does Breastfeeding Cause Sagging Breasts?

A good friend of mine told me that she wasn't going to breastfeed, not because she didn't believe in the health benefits, but because she was afraid her breasts would sag. I can now tell her that her belief may not be true.

According to a Medical News Today article, breastfeeding does not create sagging breasts. Even more, it doesn't have an impact on a woman's breast shape. A study of 93 women who were breastfeed one or more children. Researchers found that there were no significant factors for a sagging breast.

"Many women who come in for breast surgery tell us their breasts are sagging, drooping or are less full because they breastfed," said Brian Rinker, MD, ASPS Member Surgeon and study author. "Although the amount of sagging in the breasts appears to increase with each pregnancy, we've found that breastfeeding does not worsen the effect."

The study examined 93 women who were pregnant one or more times prior to having cosmetic breast surgery. Fifty-eight percent of patients reported breastfeeding one or more of their children. The duration of breastfeeding ranged from 2 to 25 months, with an average of nine months. Fifty-five percent of respondents reported an adverse change in the shape of their breasts following pregnancy.

As the first study to examine what impacts breast shape in connection to pregnancy, plastic surgeons found that a history of breastfeeding, the number of children breastfed, the duration of each child's breastfeeding, or the amount of weight gained during pregnancy were not significant predictors for losing breast shape. However, body mass index (BMI), the number of pregnancies, a larger pre-pregnancy bra size, smoking history, and age were significant risk factors for an increased degree of breast sagging.

Nearly 104,000 women had breast lifts in 2006, up 96 percent since 2000, according to the ASPS. In addition, more than 329,000 women had Breast augmentation, making it the top surgical cosmetic procedure in 2006.

"Women may be reluctant to breastfeed because of this unfounded myth that doing so means the end of youthful breasts," said Dr. Rinker. "Now, expectant mothers can relax knowing breastfeeding does not change the appearance of their breasts."
