Does a positive BV status affect pregnancy?

The result of a positive Bv test is that the number of lactobacilli in the reproductive tract is reduced, which can cause vaginal diseases, which has a great impact on your pregnancy. When Bv is positive, it is best not to conceive. We should treat the condition first, otherwise it will easily cause vaginitis. Otherwise, even if we get pregnant, it will easily cause miscarriage. Now let us understand the impact of BV positivity on pregnancy.

BV refers to a clinical syndrome characterized by a decrease in the number of normal genital tract flora (H202-producing Lactobacillus) and an increase in the number of anaerobic bacteria (Bacteroides, Gardnerella, Mobilunella, Mycoplasma hominis and Streptococcus, etc.).

It is called bacterial because there is an obvious abnormal growth of large amounts of anaerobic bacteria; it is called vaginosis because there is an increase in vaginal secretions, but there is no inflammatory response seen in clinical vaginitis, and there is no local increase in white blood cells.

The study of BV has a history of more than a century. In the past, due to limited understanding of it, various articles reported many names, such as "nonspecific vaginitis, vaginal Gardnerella vaginitis, vaginal Haemophilus influenzae vaginitis", etc. Until now, many domestic clinicians still call this type of patients "nonspecific vaginitis". In order to achieve a unified name, the 1984 Swedish International Academic Conference officially named it "Bacterial Vaginosis".

Bacterial vaginosis (BV) is a mixed infection caused by vaginal Gardnerella and some hypoxic bacteria, which leads to an imbalance of the microecological balance in the vagina, causing a syndrome of increased vaginal discharge, fishy leucorrhea, and vulvar itching and burning.

What medicine is good for bacterial vaginosis?

1. General treatment

Keep the vulva clean and dry and avoid scratching. Do not eat spicy foods. Change your underwear frequently and wash it with warm water. Do not mix it with other clothes to avoid cross infection.

2. Drug treatment

(1) Metronidazole. It is currently believed to have reliable therapeutic effects and should be taken twice a day for 7 consecutive days.

(2) Methicillin (clomiphene). Shared for 3 days.

(3) Thiamphenicol (Thiamycin). It is effective against a variety of Gram-negative and Gram-positive bacteria, and has a good therapeutic effect on the growth of anaerobic bacteria, so it can also be used.

(4) Cleansing and ampicillin can also be used. In recent years, it has been advocated that no treatment is needed for asymptomatic people.

3. Local therapy

Topical medications can be used for treatment, such as metronidazole suppositories, once a night for 7 consecutive days.

4. Treatment of comorbidities

If other pathogens are detected, use medications targeting those pathogens to avoid the abuse of antibiotics. Pay attention to the medication for systemic conditions, and provide support and immunotherapy at the same time, and pay attention to adverse drug reactions.

5. Treatment of sexual partners

Male sex partners are treated at the same time.

Prevention of bacterial vaginosis

Bacterial vaginosis is very harmful to women, so it is necessary to prevent bacterial vaginosis in daily life. Here are seven ways to prevent bacterial vaginosis:

1. Try to use condoms during sexual intercourse to prevent cross infection. After diagnosis, you should seek treatment together with your sexual partner.

2. Develop healthy living habits, maintain regular living and eating habits, eat a light diet, avoid spicy and irritating foods, exercise regularly, and improve the body's immunity.

3. Actively treat diabetes, tinea manuum, and tinea pedis.

4. After receiving regular treatment, regular check-ups should be conducted after each menstruation. Consolidation treatment should be carried out when necessary. The condition can be considered cured only if all check-ups are normal.

5. Pay attention to personal hygiene and wash the vulva with warm water every day. Do not use various lotions or medicines to rinse the vulva and vagina.

6. Do not use sanitary pads, change your underwear every day, wear pure cotton underwear, keep the vulva clean and dry, do not mix underwear with other clothes, and it is best to dry it in the sun after washing.

7. Strengthen self-protection awareness to avoid cross infection caused by sauna, swimming and use of public bathroom supplies.
