METHOD: A clinical study was designed to evaluate the change in breast measurements resulting from pregnancy without breastfeeding (control group n=62) vs. pregnancy with breastfeeding (study group n=57) in women who had breast augmentation. Measurements included the mid-clavicle to nipple distance and the nipple to inframammary fold (IMF) distance. The degree of breast ptosis using Regnault’s classification was also documented. Measurements were made before pregnancy and one year after pregnancy in the control group or one year after completing breastfeeding in the study group. Basic demographic data was also collected including age, body mass index, bra size, and the duration of breastfeeding.
RESULTS: The groups were not significantly different regarding age (24±5 vs. 25±6), body mass index (23±3 vs. 22±4) or mean bra size 34-C. The mean duration of breastfeeding for the study group was 6±3 months. Breast ptosis, as indicated by the increase in the breasts’ measurements, was not significantly different between the study and the control group (table 1).

CONCLUSION: The significant changes in breast measurements are caused by the pregnancy. Breastfeeding does not appear to cause further breast ptosis in women with breast augmentation. Since breastfeeding improves both a mother and child’s overall health, patient education regarding this matter is of importance.
