What causes excessive white vaginal discharge with a fishy odor?

Under normal circumstances, increased vaginal discharge with a fishy odor may be caused by personal hygiene issues, normal post-coital changes, endometritis, cervicitis, bacterial vaginosis, or other factors. If the above symptoms occur, it is recommended to seek medical attention promptly. Specific analyses are as follows:

1. Personal Hygiene Issues

Poor personal hygiene habits, such as infrequent underwear changes or improper cleaning methods, may lead to bacterial growth, resulting in increased vaginal discharge accompanied by a fishy odor. It is recommended to wash the external genital area daily, keep it dry, change underwear regularly, and choose breathable cotton underwear.

2. Normal Post-Coital Phenomenon

After sexual intercourse, changes in the vaginal environment and increased secretions may cause an increase in vaginal discharge with a mild fishy odor. Women should maintain good sexual hygiene to prevent infections.

3. Endometritis

Endometritis is an inflammation of the uterine lining caused by infection with bacteria or other pathogens. Inflammatory stimulation may lead to increased vaginal discharge with a fishy odor, often accompanied by lower abdominal pain, fever, and menstrual irregularities. Patients should follow medical advice and use medications such as cefixime capsules, levofloxacin tablets, and Gynecological Qianjin tablets for treatment.

4. Cervicitis

Cervicitis is an inflammation of the cervix caused by infection with bacteria, viruses, or other pathogens. Inflammation may result in increased vaginal discharge with a fishy odor, typically accompanied by contact bleeding of the cervix, and pain in the lower back or abdomen. Patients should follow medical guidance and use medications such as azithromycin tablets, roxithromycin capsules, and Gongyanping tablets for treatment.

5. Bacterial Vaginosis

Bacterial vaginosis is a mixed infection caused by imbalance of the normal vaginal flora, primarily involving pathogens such as Gardnerella and anaerobic bacteria. It may lead to increased vaginal discharge with a fishy odor, often accompanied by symptoms like vulvar itching and a burning sensation. Patients can use clindamycin phosphate vaginal gel, Fujieshu wash solution, metronidazole tablets, or similar medications under the guidance of a physician.

To maintain women's health, in addition to practicing good personal hygiene, it is important to maintain sexual hygiene, prevent infections, and undergo regular gynecological examinations to detect and treat gynecological conditions early.
