What causes a fishy odor in women's vaginal discharge?

Foul-smelling vaginal discharge in women may be caused by diseases such as vaginitis, pelvic inflammatory disease, or cervicitis. Treatment should be carried out under a doctor's guidance based on the specific underlying cause. Details are as follows:

1. Vaginitis

Poor hygiene and inadequate care of the genital area may lead to viral or bacterial infections causing inflammation, resulting in vaginal discharge with a fishy odor. It is recommended to follow medical advice and use anti-inflammatory medications such as clindamycin hydrochloride tablets, metronidazole sustained-release tablets, or tinidazole tablets.

2. Pelvic Inflammatory Disease (PID)

When the pelvic region becomes inflamed due to infection by chlamydia or Neisseria gonorrhoeae, the inflammatory irritation may cause vaginal discharge with a strong fishy odor. Under medical supervision, treatment may include ceftriaxone sodium injection, metronidazole tablets, or ofloxacin tablets.

3. Cervicitis

When the cervix suffers mechanical injury and becomes infected by pathogens, it may also trigger inflammation leading to malodorous vaginal discharge. It is advisable to follow medical instructions and use medications such as moxifloxacin hydrochloride tablets, doxycycline hydrochloride tablets, or azithromycin tablets.

In addition, abnormal vaginal discharge may also occur in cases of endometritis. The exact cause should be diagnosed at a正规 hospital so that appropriate treatment can be provided accordingly.
