If vaginal exhaust occurs within one week after delivery, it is a normal phenomenon, mainly because the dewlap will press on the pelvic floor muscles after delivery, which will make the pelvic floor muscles loose, and the front and back walls of the vagina cannot be closed together after delivery, so it may cause air to enter and exhaust. If you still have exhaustion after a week, it is an abnormal phenomenon. You can do anal lifting exercises to exercise the pelvic floor muscles to improve the local laxity of the vagina. In about 42 days after delivery, you can go to the hospital for pelvic floor rehabilitation so that the pelvic floor muscles can recover as soon as possible, which will improve the sound caused by air entering and exiting the vagina due to vaginal laxity.
