Introduction

The main symptoms of bacterial vaginosis include abnormal vaginal discharge, frequent and urgent urination, itching and burning pain in the vulva, pain during sexual intercourse, and lower abdominal pain. It is important to maintain good hygiene habits in daily life, such as washing the vulva daily with warm water, avoiding the use of strong cleansers, and keeping the vulva clean and dry. Choose cotton, breathable underwear and change underwear frequently to maintain ventilation and prevent excessive moisture in the vulvar area.

　　Under normal circumstances, the symptoms of bacterial vaginosis mainly include abnormal vaginal discharge, frequent and urgent urination, itching and burning pain in the vulva, pain during sexual intercourse, and lower abdominal pain. The specific analysis is as follows:

　　1. Abnormal Vaginal Discharge

　　Bacterial vaginosis causes imbalance in the vaginal flora, allowing anaerobic bacteria to multiply extensively. The metabolic products produced alter the texture and color of vaginal discharge, making it thin and abnormally colored.

　　2. Frequent and Urgent Urination

　　Because the vagina is adjacent to the urethra, inflammation caused by bacterial vaginosis can spread to the urethra, irritating the urethral mucosa, increasing its sensitivity, and subsequently causing symptoms of frequent and urgent urination.

　　3. Itching and Burning Pain in the Vulva

　　Due to the inflammatory response within the vagina and the irritation from abnormal discharge, patients may experience symptoms of itching and burning pain in the vulva. The severity varies; some patients may only experience mild discomfort, while others may feel unbearable pain and itching.

　　4. Pain During Sexual Intercourse

　　In cases of bacterial vaginosis, the vaginal environment has already changed. The presence of inflammation makes the vaginal walls more sensitive and fragile. Therefore, during sexual intercourse, the irritation and discomfort may intensify, leading to pain during intercourse.

　　5. Lower Abdominal Pain

　　In rare cases, bacterial vaginosis may spread to areas such as the pelvic cavity or uterine adnexa. At this time, patients may feel mild lower abdominal pain. This pain typically occurs intermittently and may be accompanied by other symptoms such as back pain and frequent urination.

　　In daily life, one should maintain good hygiene habits, wash the vulva daily with warm water, avoid using strong detergents, and keep the vulva clean and dry. Choose cotton, breathable underwear, and change underwear frequently to maintain ventilation and breathability of the vulva.
