After delivery, the pelvis will return to its pre-pregnancy state on its own. At about 42 days after delivery, the uterus will gradually return to its non-pregnant state, and it will take longer for the pelvis and pelvic floor muscle tissue to recover. During pregnancy due to the influence of hormone levels and the relaxin secreted in late pregnancy, it will lead to ligament relaxation around the pelvis and make the pelvis less stable, plus the pressure of the fetus into the pelvic floor tissues, which will lead to further ligament relaxation and pelvic floor fascia damage. After delivery, the mother needs to pay attention to bed rest, the pelvis will return to its normal state on its own. The mother can also promote the repair of the pelvis through abdominal belts, physical therapy and calcium supplementation to shorten the recovery time to a certain extent. Women should pay attention to proper physical exercise, especially the exercise of pelvic floor muscles to avoid prolapse of the uterus or vagina. At the same time, women can also do health exercises to promote faster recovery of the body. In addition, in terms of diet, it is necessary to consume more high-quality protein, such as lean meat, eggs, milk, etc.
