What Causes a Queef? Fact-Checking Myths About Vaginal Flatulence

Is what Causes a Queef? Fact-Checking Myths About Vaginal Flatulence a hot topic right now? Uncover expert findings below.

While isolated vaginal gas is harmless, there is one distinct clinical exception. A rectovaginal fistula is an abnormal epithelialized tract connecting the rectum directly to the vaginal vault. When this barrier is compromised, true intestinal gas, liquid stool, and bacteria bypass the anal sphincter and exit through the front.

This condition is uncommon, documented in fewer than 0.1% to 0.5% of routine vaginal deliveries in high-income healthcare systems, though risk increases during complex third- or fourth-degree perineal tears. Other primary causes include severe Crohn’s disease, pelvic radiation therapy, and complications from colorectal surgery.

A rectovaginal fistula comes with unmistakable warning signs. Unlike ordinary vaginal flatulence, fistula-induced gas has a strong, persistent fecal odor. Patients experience recurrent vaginal infections, unexplained discharge containing fecal particles, and localized pain. Anyone noticing these symptoms should contact a urogynecologist or colorectal surgeon for an immediate physical examination.
