If there is gas coming out of the vagina, the best treatment: first, gain weight. Second, exercise the pelvic floor muscles. The main reason why there is gas in the vagina is because the front and back walls of the vagina are not close together because of the thin body. This creates a gap, so that gas enters the vagina through the gap, and then exits the vagina and makes a sound. In this case, it is mainly due to the laxity of the vaginal wall. Also, if you are too thin, the pelvic floor muscles are not developed, which can cause the front and back walls of the vagina to not fit tightly. Therefore, it is important to do anal contraction exercises or pelvic floor rehabilitation. This will make the front and back walls of the vagina stick together so that air cannot flow in. Also, strengthen nutrition, give fattening, and when the pelvic floor muscles are plump, gas will not enter.
