What causes a fishy odor in the genital area?

Generally, vaginal odor may be caused by poor personal hygiene, menstruation, bacterial vaginosis, trichomonas vaginitis, pelvic inflammatory disease, or other reasons. If discomfort occurs, please seek medical attention promptly. Detailed explanations are as follows:

1. Poor Personal Hygiene

Failure to change underwear regularly or improper cleaning may lead to bacterial growth and cause an unpleasant odor. Maintain good personal hygiene by washing the genital area daily, choosing breathable cotton underwear, avoiding tight-fitting clothing, and reducing environments conducive to bacterial growth.

2. Menstruation

During menstruation, a mixture of blood and secretions can easily become a breeding ground for bacteria. Particularly, the iron contained in blood can be utilized by bacteria to produce odor. When using sanitary pads, ensure timely changes and maintain cleanliness and dryness of the genital area.

3. Bacterial Vaginosis

Bacterial vaginosis is caused by mixed infection with Gardnerella vaginalis and anaerobic bacteria, leading to imbalance of the vaginal flora, resulting in a fishy odor. Symptoms may also include increased vaginal discharge and itching of the vulva. Treatment may include medications such as Levofloxacin Hydrochloride Capsules, Clindamycin Capsules, and Fluconazole Oral Solution, under the guidance of a qualified physician.

4. Trichomonas Vaginitis

Trichomonas vaginitis is caused by Trichomonas vaginalis. The parasites multiply in the vagina, consuming glycogen in vaginal epithelial cells, thereby compromising the vagina's natural self-cleaning and defense mechanisms, causing the aforementioned symptoms, which may be accompanied by itching and burning of the vulva. It is recommended to follow medical advice and use medications such as Tinidazole Tablets, Metronidazole Vaginal Effervescent Tablets, and Ornidazole Dispersible Tablets for treatment.

5. Pelvic Inflammatory Disease

Pelvic inflammatory disease is an inflammation caused by pathogenic organisms invading the pelvic cavity. These organisms multiply in the pelvic cavity and produce toxins, leading to increased secretions accompanied by a fishy odor. Symptoms may also include fever and lower abdominal pain. It is necessary to follow medical advice and use medications such as Qianjin Zhidai Pills, Gynecological Qianjin Tablets, and Metronidazole Tablets for treatment.

Increasing water intake appropriately can promote urination, helping to flush the urinary tract and reduce odor.
