Pelvic repair is usually better done within 42 days to six months after delivery. In the late stage of pregnancy, the uterus increases in size due to the gradual growth of the fetus, which tends to change the pelvis, and the hormonal influence of pregnant women during pregnancy also causes the pelvic floor muscles and ligaments to relax, in preparation for childbirth. After delivery, the pelvic floor muscles and ligaments are still in a state of relaxation. Within 42 days after delivery, the hormone secretion in the body gradually normalizes, and pelvic bone repair is more effective at this time. The pelvic floor muscles and ligaments need to be exercised to increase their elasticity so that the pelvis can be restored to its pre-pregnancy level as soon as possible. If you need pelvic repair after delivery, you need to do it under the guidance of a professional doctor so as not to cause unnecessary damage to your body.
