Sagging breasts

Will breastfeeding make my breasts sag?

Breastfeeding has little or no effect on the appearance of breasts, several studies suggest. Another one showed an increased risk of sagging in women who breastfed for seven or more months. The more common reasons for sagging breasts are obesity and pregnancy.

A) Breast sagging

While breastfeeding, the fat in the breast is used to make milk. The fat regrows after weaning. A very small number of women lose a lot of the fat in the breast during breastfeeding. Their breasts can become very saggy and the skin can even be wrinkled. The breasts of most of these women return to a more typical appearance within three years unless they get pregnant again (Lawrence 2016).

Studies on the relationship between breastfeeding and breast sagging showed that breastfeeding had very little (Pisacane 2004) or no (Arefanian 2018; Rinker 2010; Rinker 2008) impact on the appearance of the breasts.

One study (Huang 2017) of Chinese women showed an increased risk of sagging if they breastfed for seven or more months.

Other more common factors that increase the risk of sagging are obesity (Huang 2017) and pregnancy (Pisacane 2004).
