It is normal for a woman’s pelvis to widen to a certain extent after giving birth compared to before pregnancy. It can be improved through postpartum recovery, for example, through postpartum recovery gymnastics, shaping exercises, corsets and other methods to improve. The widening of the pelvis in women is mainly due to the compression and expansion of the pelvis by the enlarged uterus during pregnancy and the deformation of the pubic symphysis in women during childbirth, which will recover to a certain extent over time. It is difficult to return to the way it was before pregnancy and childbirth, but for women with high body requirements, targeted exercises can be used to improve. The most effective way is to repair the pelvic floor through the guidance of a doctor, and at the same time, you can do appropriate exercises, such as yoga to promote pelvic bone repair.
