Breastfeeding May Not Have an Effect on Breast Appearance

As a growing number of women turn to plastic surgeons for breast lifts and breast augmentation  to counteract the effects of pregnancy on their bodies, one common postpartum complaint is sagging breasts, also known as breast ptosis, which many believe to be linked to breastfeeding. However, as this new study demonstrates, it appears that other factors are responsible for the breast sagging experienced by some women after pregnancy which include: older age, higher body mass index (BMI) and a history of smoking

This study indicates that fifty-four of the patients (58%) studied had a history of breastfeeding one or more children; 39 patients did not breastfeed.  Weight gain during pregnancy across both groups ranged from five to 45 kilograms and 39% reported a history of smoking. Fifty-one respondents described an adverse change in breast shape following pregnancy.  BMI and weight gain during pregnancy were both significantly higher in the non-breastfeeding group. 

Analysis of this information showed that greater age, higher BMI, greater number of pregnancies, larger pre-pregnancy bra cup size, and history of smoking were all significant risk factors in the development of sagging breasts.  Breastfeeding, however, was not - even as duration of breastfeeding increased. 

It is important to be informed with objective data rather than general assumptions or "word of mouth" information when considering cosmetic breast procedures. This study represents a concrete foundation by providing solid information for those who are concerned about the potential aesthetic impact of breastfeeding and is consistent with the American Society for Aesthetic Plastic Surgery's objectives to have member-surgeons practice evidence-based medicine with patient safety at the forefront as well as to perform procedures that are recognized for efficacy, striving for positive outcomes.
