What causes bacterial vaginosis after childbirth?

Bacterial vaginitis generally refers to bacterial vaginosis. Postpartum bacterial vaginosis may be caused by hormonal changes, poor hygiene, low immunity, vaginal flora imbalance, or infection from a sexual partner. Management should be based on the specific cause. Detailed analysis is as follows:

1. Hormonal changes: After childbirth, estrogen levels in women drop sharply, which may disrupt the balance of vaginal flora and lead to bacterial vaginitis. It is recommended to maintain a light diet, healthy sleep schedule, and stable hormone levels.

2. Poor hygiene: Inadequate personal hygiene after delivery—such as incomplete cleaning or using inappropriate cleansing products—may also contribute to bacterial vaginitis. It is advised to improve personal hygiene practices and use mild, non-irritating cleaning products.

3. Low immunity: The body of a postpartum woman is in a recovery phase with relatively weakened immunity, making her more susceptible to bacterial invasion. It is recommended to increase nutritional intake, ensure sufficient rest, and engage in moderate exercise to enhance immune function.

4. Vaginal flora imbalance: The vaginal microbiota may change after childbirth, resulting in reduced beneficial bacteria and increased harmful bacteria, thus triggering the condition. It is recommended to use medications such as Hongnu Fuyan Wash Solution, miconazole nitrate suppositories, or metronidazole gel under medical guidance to relieve symptoms.

5. Infection from sexual partner: If the woman's sexual partner has an infection, such as urethritis or prostatitis, bacteria may be transmitted during sexual intercourse, causing vaginal inflammation. It is recommended to follow medical advice and use medications such as metronidazole suppositories, Baofu Kang suppositories, or clotrimazole vaginal tablets to improve the condition.

If a woman experiences discomfort after childbirth, she should promptly seek medical attention and receive active treatment under a doctor’s guidance.
