There is no special position for sleeping after cesarean section to repair the pelvis. Generally speaking, the postpartum sleeping posture can choose to lie on the side or lie flat alternately, but there is no obvious effect on the repair of the pelvic bone, if the pelvic bone problem is more serious, it is recommended to consult a doctor in time for symptomatic treatment. Postpartum pelvic problems are generally the problem of pelvic floor muscle relaxation, you can use Kegel exercises, anal exercises, such as contraction of the anal sphincter, the muscles around the vagina, to prevent post-partum urinary leakage and pelvic organ prolapse, but the sleeping position is not able to repair anything. It takes some time for a postpartum woman to recover her body, and if any abnormalities occur, it is recommended that she seek medical attention promptly.
