Breasts go through a lot of changes during the childbearing process. They can go up several cup sizes during pregnancy and breastfeeding. What happens afterward differs amongst women.
Deflation – After the pregnancy and lactation hormones go away, you lose all the extra breast volume you had gained. However, the stretched skin may not shrink back to pre-baby. This can leave you feeling like your breasts have been emptied or deflated. Women have reported that their breasts become smaller than they were before having a baby.
Sagging – For some women, the breast skin has been expanded so much from all the breast growth that the breasts begin to sag. You may notice that your nipples are lower and may even point down. This is called “ptosis.”
Large breasts – Once pregnancy hormones subside, some women find that their breasts enlarged permanently. This can be bothersome especially to women who were large-breasted, to begin with. This can lead to other medical conditions such as back pain or rashes.
