Introduction
Due to excessive growth of anaerobic bacteria, Gardnerella, and other bacteria, large amounts of amine substances are produced, leading to symptoms with a fishy odor. The overgrowth of anaerobic trichomonads in the vagina can cause vaginal inflammation, resulting in a fishy smell. Additionally, bacterial proliferation in the endometrium leads to increased uterine cavity secretions, and inflammatory discharge may produce a foul, fishy odor.
Under normal circumstances, a fishy odor in female vaginal discharge is often caused by bacterial vaginosis, trichomoniasis, or endometritis. Specific details are as follows:
1. Bacterial Vaginosis
After infection with bacterial vaginosis, anaerobic bacteria such as Gardnerella multiply rapidly and produce large amounts of amine substances, leading to a fishy odor. This is often accompanied by increased vaginal discharge and itching. Medications such as metronidazole suppositories or tinidazole suppositories may be used according to medical advice.
2. Trichomoniasis
The overgrowth of Trichomonas vaginalis, an anaerobic protozoan, causes inflammation in the vagina, resulting in a fishy-smelling discharge. Treatment may include medications such as xiaomi vaginal effervescent tablets or nifuratel-nystatin vaginal soft capsules, as directed by a physician.
3. Endometritis
Bacterial growth and reproduction in the endometrium lead to increased uterine cavity secretions. These inflammatory secretions often have a foul, fishy odor and are accompanied by symptoms such as abdominal pain and increased vaginal discharge. Treatment under medical guidance may include gynecological qianjin tablets, levofloxacin capsules, or amoxicillin capsules.
In addition to the above conditions, other diseases such as cervicitis, endometrial cancer, and cervical cancer may also cause similar symptoms. It is recommended to temporarily avoid sexual intercourse and seek timely gynecological evaluation and treatment.
