The pregnant body is mesmerizing. It goes through so many extraordinary changes in order to support the growth of a whole new life. Every organ and system is involved, including the skin, uterus, lungs, spine, muscles, ligaments, kidneys, heart, and blood vessels. Considering the extent of your body's contribution, it is unrealistic to think that it will quickly and easily bounce right back to it’s pre-pregnancy state soon after birth. Instead, you can expect some common temporary and permanent body changes after childbirth.
