Introduction
Under normal circumstances, increased vaginal discharge with a fishy odor may be related to improper personal hygiene habits, excessive vaginal cleansing, senile vaginitis, bacterial vaginosis, trichomonas vaginitis, and other causes. It is recommended that patients wash the vulva daily with warm water, or use medications such as Baofukang suppository, Nifuratel tablets, or Xiaomi vaginal effervescent tablets under the guidance of a physician.

Generally, increased vaginal discharge with a fishy odor may be related to improper personal hygiene habits, excessive vaginal cleansing, senile vaginitis, bacterial vaginosis, trichomonas vaginitis, and other causes. It is recommended that patients wash the vulva with warm water daily or use medications such as Baofukang suppository, Nifuratel tablets, or Xioami vaginal effervescent tablets under a doctor's guidance. A detailed analysis is as follows:

1. Improper personal hygiene habits: Long-term failure to clean the vulva or infrequent changing of underwear may lead to accumulation of dirt, causing a fishy odor and possibly accompanied by discomfort of the vulva. It is recommended to improve personal hygiene habits, wash the vulva with warm water daily, and keep the vulvar area clean and dry.

2. Excessive cleansing: Over-cleansing may disrupt the balance of vaginal flora, leading to increased vaginal discharge, possibly accompanied by mild itching or burning pain. It is recommended to reduce the frequency of vaginal cleansing and use of vaginal cleansers, simply washing the vulva with warm water.

3. Senile vaginitis: Decreased estrogen levels cause vaginal wall atrophy and reduced local resistance, allowing pathogenic bacteria to invade and cause inflammation. Symptoms may include vulvar itching, increased vaginal discharge, changes in color and odor, and sometimes a fishy smell. Patients should follow medical advice to use medications such as Baofukang suppository, metronidazole tablets, or estradiol valerate tablets for treatment.

4. Bacterial vaginosis: Poor personal hygiene leads to imbalance of vaginal flora, causing abnormal proliferation of pathogenic bacteria such as Gardnerella and anaerobic bacteria, resulting in bacterial vaginosis. Symptoms may include increased vaginal discharge, accompanied by itching of the vulva and a fishy odor. Patients should use medications such as metronidazole suppository, Nifuratel tablets, or Tinidazole capsules under a doctor's guidance to aid recovery.

5. Trichomonas vaginitis: Infection of the vagina by Trichomonas vaginalis can cause trichomoniasis, leading to increased yellow-green frothy vaginal discharge, possibly accompanied by a fishy odor, vulvar itching, and burning sensation. Patients are advised to use medications such as Tinidazole vaginal effervescent tablets, Xioami vaginal effervescent tablets, or Ornidazole dispersible tablets under medical guidance to alleviate symptoms.

In daily life, patients should maintain vulvar hygiene, clean regularly, hand wash underwear separately, and separate from other clothing to avoid cross-infection.
