Patient's question:
How can you know if your vagina is loose or tight? Is there a way to check it yourself? First question supplement: I ask this because I make sounds during sex, like passing gas, because I read that this could be a sign of vaginal relaxation, but I haven't given birth and haven't had many sexual partners.Doctor's answer:
Your condition falls under the symptoms of "yin chui" (vaginal gas emission). Occasionally, some women visit gynecological clinics and hesitantly mention that there is a flow of air expelling from their vagina, sometimes accompanied by a sound similar to "passing gas from the anus," which leaves them extremely frightened. This is what traditional Chinese medicine refers to as "yin chui," where it is described as "when a woman's vagina constantly emits air or makes a sound during exhalation, resembling the release of flatus." Many patients feel ashamed and are reluctant to discuss this with their husbands or doctors, so the number of those seeking medical attention is far fewer than the actual number of patients, making it appear uncommon in clinical practice.So, what exactly is "yin chui," and what should one do if they experience it? Here is a brief introduction to its causes and mechanisms.
1. Postpartum weakness and "yin chui"
Most cases of "yin chui" occur in postpartum women, especially in multiparous women or those with weak constitutions. In traditional Chinese medicine, this is attributed to "great deficiency of qi and blood, and sinking of the middle Qi." To understand its pathogenesis, we must examine the changes in the birth canal during childbirth. In women who have never given birth, the vagina is shaped like a trumpet, wider inside and narrower outside. Under normal circumstances, the pelvic floor muscles and fascia surrounding the vagina maintain a certain tension, providing support to the vaginal walls, keeping them pressed together, eliminating the cavity, and sealing the vaginal opening with the labia majora, as if two closed doors, preventing air from entering. During childbirth, as the fetus passes through the birth canal, the vagina significantly expands and loosens. The pelvic floor muscles and fascia that support the vaginal walls tear or stretch excessively, losing their elasticity. As a result, the anterior and posterior walls of the vagina cannot adhere closely, forming a cavity. Perineal lacerations cause the vaginal opening to widen, failing to cover the vagina, allowing air to enter.
