The main symptoms of bacterial vaginosis

The main symptoms of bacterial vaginosis include increased vaginal discharge, fishy-smelling leucorrhea, vulvar itching, burning sensation, and pain during sexual intercourse. Patients should seek medical treatment promptly.

1. Increased vaginal discharge

Due to the infection of pathogenic bacteria, the microecology in the vagina is unbalanced, and the exudate increases under the stimulation of inflammation. It is usually manifested as a significant increase in the amount of vaginal secretions, which may be thin or dregs-like.

2. Fishy odor leucorrhea

Due to the excessive growth of anaerobic bacteria, amine substances are produced, which decompose to produce ammonia gas, thus causing the leucorrhea to have an odor. This odor mainly comes from the vagina and is more obvious after sexual intercourse.

3. Vulvar itching

Vulvar itching is mostly caused by local skin inflammation. Itching may be caused by skin allergic reactions caused by chemical components and microorganisms in vaginal secretions. Itching usually occurs near the vaginal opening and the vulva area, and in severe cases it can affect the quality of daily life.

4. Burning sensation

The burning sensation is caused by toxins or other metabolites produced by bacteria irritating the vaginal mucosa, causing local tissue redness, swelling and pain. Patients may feel a burning sensation in the vulva, especially after urination or sexual intercourse.

5. Pain during sexual intercourse

Pain during intercourse may be related to congestion and edema of the vaginal wall, or it may be due to inflammation causing the proliferation and outward migration of the columnar epithelium of the cervical canal, which covers the surface of the cervical glands, blocking the opening of the cervical glands, preventing mucus and sperm from passing smoothly, and causing infertility. This pain usually occurs at the entrance of the vagina and is particularly obvious during sexual intercourse.

In view of the symptoms of bacterial vaginitis, it is recommended to perform vaginal secretion smear microscopy and vaginal pH measurement. Treatment measures include the use of anti-anaerobic drugs such as metronidazole and tinidazole as prescribed by the doctor. Patients should pay attention to personal hygiene, change and wash underwear frequently, avoid wearing tight and non-breathable clothes, and keep the vulva dry and clean.
