Vaginal recovery is a gradual process after childbirth, and the vagina generally recovers 3-6 months after delivery. As the number of pregnancies and births increase, the elasticity of the vagina gradually decreases and may not fully recover to the state before birth, so mothers can promote vaginal recovery by the following methods: 1. Exercise repair: After delivery, you can strengthen the recovery of vaginal elasticity and promote vaginal tightness by exercising, such as consciously holding urine for a few seconds, interrupting urination, then continuing urination after a short pause, and repeatedly practicing. After a period of exercise, the muscle tension around the vagina can be improved, or you can hold your bowels when you have the urge to urinate and do anal lifting exercise, which can exercise the pelvic muscles. 2. photoelectric treatment: mothers can go to regular hospitals for pelvic floor electrical stimulation treatment and laser treatment, which can effectively promote vaginal recovery. 3. other treatment: patients who have failed through the above treatment can undergo injection treatment, by applying hyaluronic acid, autologous fat or Submucosal injection with hyaluronic acid, autologous fat or artificial dermal particles to reduce the vaginal cavity is suitable for women who are not breastfeeding after childbirth and for women whose babies are entering the lactation phase. In addition, surgical treatment is available, including traditional vaginal mucosal excision and repositioning of the perivaginal muscles with sutures, which can be effective in promoting vaginal recovery.
