During pregnancy, it is normal for breasts to become larger to develop tissues that facilitate lactation to feed your baby. However, once your milk has dried out, your breasts shrink back down to their previous size (or sometimes smaller). The skin around your breasts that had to stretch to fit over your larger breasts may not be elastic enough to fit snuggly around your downsized contours, which frequently causes droopiness.
Your abdomen is also likely to have stretched skin after your once-pregnant belly returns to its former size. This leaves significant sagging around your midsection, sometimes called a pooch. While diet and exercise can help you to remove most of your baby weight, you may also find that stubborn fat clings to your problem areas like the abdomen, thighs, and arms, which liposuction can help to recontour.
