Usually, a woman’s pelvis recovers on its own after childbirth, but the recovery time is longer. The pelvis is made up of two parts: the bone and the ligaments, and the recovery of the pelvis after childbirth also refers to the return of these two parts to normal. The influence of hormone level during pregnancy and the secretion of relaxin in the body in late pregnancy can cause the ligaments around the pelvis to relax and make it less stable, while the compression of the pelvic floor tissue by the fetus entering the pelvis can also cause the pelvic ligaments to relax and the pelvic floor fascia to be damaged. Usually the pelvis will return to normal on its own after delivery, but the pelvis and pelvic floor muscle tissues take a longer time to recover. Postpartum women should take calcium tablets in appropriate amounts, eat more high-quality protein, such as lean meat, eggs, milk, etc., and strengthen the pelvic floor muscle exercise to speed up the recovery of the pelvis itself. After delivery, avoid heavy physical labor, avoid strenuous exercise, reduce squatting exercises and avoid increasing abdominal pressure.
