Vaginal blowing: that is, the phenomenon of female vaginal exhaust. Including two situations, one is conscious involuntary discharge of gas in vagina; In another case, during sexual life, with the twitching of the penis, there is a sound in the vagina, as if air is discharged from it. Some people who feel vaginal discharge are neurotic. The patient's vagina is highly sensitive, and there is no gas discharged from the vagina, but there is conscious air flow. This is a mental and neurological symptom, not a gynecological disease. The phenomenon of vaginal exhaust is mostly caused by some pathological changes in pelvic cavity, such as rectovaginal fistula and third-degree perineal laceration, which can make air enter the vagina. When the body position changes and the vagina is compressed, gas is discharged from the vagina, resulting in vaginal blowing. Some patients with vaginitis, because bacteria ferment in the vagina, produce a lot of gas, which makes the air pressure greater than the external pressure, leading to vaginal blowing. Most of the middle-aged women who have given birth are due to the relaxation of vaginal wall and pelvic floor tissue, and the loose attachment and sealing of the front and rear walls of vagina make air enter. 1. Postpartum vaginal distension caused by physical weakness mostly occurs in postpartum women, especially women with multiple births and weak constitution. Traditional Chinese medicine belongs to "deficiency of qi and blood, stagnation of middle qi". To explore its mechanism, we must start with the change of birth canal during delivery. Although the vagina of a woman who has never given birth is trumpet-shaped, under normal circumstances, the pelvic floor muscles and fascia outside the vagina maintain a certain tension, which produces a Ti Tuo effect on the vaginal wall, making the front and rear walls of the vagina stick together, the lumen disappears, and the labia majora and labia majora on both sides of the vulva close to cover the vaginal opening, like two closed doors, preventing air from entering the vagina. During delivery, when the fetus passes through the birth canal, the vagina obviously expands and relaxes; The muscle tissue and fascia of Ti Tuo's vaginal wall in pelvic floor are broken, or overstretched and lose elasticity, so that the anterior and posterior vaginal walls can not be closely adhered to form a cavity. Perineal laceration opens the vaginal opening, which cannot cover the vagina and allows air to enter the vagina. This situation can generally be recovered during the puerperium, but some women can't fully recover, especially in the process of delivery, the labor process is too long, the fetus is large or the pelvis is narrow, which makes it difficult to deliver the fetus, and vaginal surgery, such as forceps delivery or suction delivery, will seriously damage the pelvic floor tissue and make it difficult to recover. Due to repeated injuries of the birth canal, many parturients naturally have vaginal relaxation. Although pregnant women's physical weakness is not serious, their recovery is slow. Under the above circumstances, when the vagina forms negative pressure (such as lying on your back, inhaling, etc. ), air enters the deepest part of the vagina (vault). When you get up or increase abdominal pressure, air is discharged from the vagina with frequent noises. There are three ways to deal with this kind of yin blowing: (1) taking drugs that greatly tonify qi and blood and enhance middle qi; (2) enhance physical fitness and promote postpartum recovery; (3) Local muscle exercise, besides postpartum health care exercise, focuses on pelvic floor, anus and vagina muscle contraction exercise, which is helpful to the recovery of birth canal. 2. Vaginal infection Some women suffering from vaginitis also have the phenomenon of vaginal exhaust, but in such patients, the airflow discharged from the vagina is mostly weak, and more importantly, there is an increase in leucorrhea, pruritus vulvae or vaginal discomfort. This is because microorganisms infected with vagina will produce gas and exist in vagina during reproduction. When posture changes or abdominal pressure increases, these gases will be discharged from the vagina. Most pathogenic microorganisms are anaerobic bacteria or trichomonas vaginalis. In this case, you should go to the hospital to see a gynecologist and treat under the guidance of a doctor. 3. rectovaginal fistula This is a rare cause. Because there is an abnormal channel (fistula) between rectum and vagina, when the anus exhausts, a small amount of gas enters the vagina through the fistula and then is discharged from the body. The reason may be congenital or acquired. The former is called congenital rectovaginal fistula, which exists at birth, so symptoms begin to appear from newborns. The latter is mainly caused by birth injury, rectal or vaginal surgery trauma, or advanced cancer, rectal and vaginal septum necrosis. Symptoms appear after delivery or shortly after surgery, or accompanied by advanced cancer (pus and blood in stool or vagina). This situation needs to go to the hospital for examination, repair surgery or treatment of cancer.
