What are the causes of vaginal flatulence?

Generally speaking, vaginal flatulence refers to vaginal gas expulsion. Vaginal gas expulsion may be caused by improper diet, obesity, vaginal laxity, trichomonas vaginitis, rectovaginal fistula, and other factors. If the above situations occur, it is recommended to seek medical treatment promptly. Detailed analysis is as follows:

1. Improper Diet

Foods such as legumes, onions, garlic, and carbonated beverages can produce large amounts of gas during digestion. Some of this gas may enter the vagina through the intestines, leading to vaginal gas expulsion. It is important to adjust dietary habits and avoid consuming these foods regularly.

2. Obesity

In individuals with excessive weight, increased intra-abdominal pressure due to fat accumulation may lead to vaginal gas expulsion. Weight reduction through lifestyle modifications may help alleviate this condition.

3. Vaginal Laxity

Vaginal laxity can result from multiple childbirths, hormonal changes, and other factors. When the vagina becomes loose, air can more easily enter the vagina, resulting in gas expulsion. This may be accompanied by symptoms such as dissatisfaction during sexual intercourse and urinary incontinence. Pelvic floor muscle exercises under a physician's guidance are recommended. Strengthening the contraction ability of the pelvic floor muscles can help improve vaginal laxity.

4. Trichomonas Vaginitis

Trichomonas vaginitis is caused by infection with Trichomonas vaginalis. Infiltration of inflammatory cells leads to increased vaginal discharge, and bacterial fermentation produces significant amounts of gas, which is expelled when standing up or when abdominal pressure increases, causing vaginal gas expulsion. Symptoms such as itching of the external genitalia and increased vaginal discharge may also be present. Patients should follow medical advice to take medications such as metronidazole tablets, ornidazole dispersible tablets, or tinidazole-clotrimazole effervescent tablets for treatment.

5. Rectovaginal Fistula

Rectovaginal fistula may be associated with surgery, inflammation, or other causes. When a rectovaginal fistula is present, gas, liquid, or even feces from the rectum may pass through this abnormal channel into the vagina, resulting in vaginal gas expulsion. Symptoms such as abdominal pain and difficulty defecating may also occur. Under medical guidance, surgical repair of the rectovaginal fistula can be performed. The fistulous opening can be accessed via the vaginal route, surrounding tissue debrided and trimmed, and then the healthy vaginal and rectal wall tissues sutured in layers to close the fistula and restore normal anatomical separation between the rectum and vagina.

To prevent vaginal gas expulsion, individuals should maintain a balanced diet, avoid excessive weight gain, practice good personal hygiene, and undergo regular gynecological examinations to maintain reproductive system health.
