Patient's question:
What is the reason for gas in the vagina?Doctor's answer:
Hello; Your condition is a symptom known as "yin chui"! Occasionally, some women visit gynecology clinics and hesitantly mention that there is a flow of air coming out of their vagina, sometimes accompanied by a sound, resembling the release of gas from the rectum, which leaves them extremely frightened. This is what traditional Chinese medicine refers to as "yin chui," where "if a woman's vagina frequently releases air or makes a sound like flatus, it is called yin chui." Many patients feel ashamed and dare not tell their husbands or doctors, so the number of those seeking medical attention is much smaller than the actual number of patients, making it seem rare 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 origins and causes.
1. Postpartum weakness and yin chui: Most cases of yin chui occur in postpartum women, especially in multiparous women with weak constitutions. From a traditional Chinese medicine perspective, this is attributed to "great deficiency of qi and blood, and sinking of the middle Qi." To understand its mechanism of occurrence, we must look at the changes in the birth canal during childbirth. In women who have never given birth, the vagina is shaped like a trumpet, with a wider inner cavity and narrower outer opening. However, under normal conditions, 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 ensuring that the labia majora on both sides of the external genitalia close, covering the vaginal opening like two closed doors, preventing air from entering the vagina. 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. The perineal laceration causes the vaginal opening to widen, failing to cover the vagina, allowing air to enter
