What causes a fishy vaginal odor? Fishy vaginal odor is usually caused by 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. It can be divided into Haemophilus vaginitis, Corynebacterium vaginitis, hypoxic bacterial vaginitis, Gardnerella vaginitis, etc. This disease can also be transmitted through sexual contact, and the incidence rate is higher among people with promiscuous sexual relations. A smear examination of the secretions can reveal a large number of pus balls and find the pathogenic bacteria.

Causes of bacterial vaginosis include:

1. Indirect contact infection

Contact with toilets, bathtubs, bath seats, towels in public toilets that are contaminated with bacteria, and using unclean toilet paper can cause infection.

2. Sexual transmission

It is one of the causes of the disease. At least 10% of men with symptoms on the female side have bacterial urethritis.

3. Taking large amounts of antibiotics

Antibiotics change the vaginal microenvironment, causing pathogenic bacterial pathogens to multiply and leading to localized bacterial vaginosis.

4. Excessive attention to hygiene

In order to maintain hygiene, some women often use medicated washes to irrigate the vagina, which can easily destroy the acid and alkaline environment of the vagina and make it easy to get bacterial vaginitis.

Treatment for bacterial vaginosis is as follows:

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 considered to have reliable therapeutic effects, taken twice a day for 7 consecutive days.

2. Methicillin: (clomiphene) for 3 days.

3. Thiamphenicol (Sulfamycin): 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, and can also be used.

3. 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.

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.
