There is no uniform standard for how many centimeters the pelvis will widen after delivery, and the pelvis can be repaired after delivery. The widening of the pelvis after delivery is mainly caused by factors such as compression of the pelvis by the growing uterus after pregnancy, pelvic dilatation, and deformation of the pubic bone during delivery. However, the specific centimeters of pelvic widening vary from person to person, with some people getting wider and some getting less, and there is no uniform standard. It is normal for the pelvis to widen after delivery. After delivery, a woman’s pelvis can be slowly repaired to further shorten the pelvic distance. If a woman is particularly sensitive to her body shape and finds that her pelvis is much wider after delivery than before pregnancy, she can improve it through shaping exercise workouts, gymnastics, wearing shapewear, postnatal yoga, and so on. When the pelvis becomes wider after delivery, the woman can also go to the hospital to get a doctor’s guidance to repair it.
