Why does the vagina have a fishy odor?

If the vagina emits a fishy odor, it actually means that there is something abnormal in the vagina and it needs to be treated or conditioned as soon as possible. The reasons for the fishy smell in the vagina are mainly related to the following diseases, such as vaginal trichomoniasis infection, bacterial vaginosis, etc., so female friends should also pay attention to it and do a timely diagnosis of the disease.

What causes a fishy vaginal odor?

1. Trichomonas vaginalis infection

This infection can easily cause an increase in vaginal discharge, accompanied by a foul odor, and itching of the genitals. It is generally believed that this infection is a type of sexually transmitted disease, which can easily be transmitted between sexual partners. It will cause an odor in the vagina. During treatment, the sexual partner must be treated at the same time to prevent cross-infection and achieve a complete cure.

2. Bacterial vaginosis

Bacterial vaginosis is one of the most common vaginal infections in women of childbearing age. It is a syndrome caused by multiple pathogens, mainly anaerobic bacteria, without any signs of vaginal mucosal inflammation. The main symptoms are increased vaginal discharge accompanied by a fishy odor. In the past, this disease was considered to be a nonspecific vaginitis or Gartner's vaginitis, but because this disease has no signs of vaginal inflammation and the changes in vaginal discharge are very obvious, it is called bacterial vaginosis. Clue cells can be found in the leucorrhea smear, the pH value of the vaginal fluid increases to above 4.5, and a positive amine test is its characteristic change.

3. Not paying attention to hygiene

Some women do not pay attention to the cleanliness of their vulva, especially during menstrual hygiene, or they do not clean before sexual intercourse, failing to ensure the cleanliness of both parties, which will lead to unclean sexual life. Due to unhygienic conditions, the vagina may be infected with bacteria, causing odor. Therefore, female friends must pay attention to personal hygiene in daily life.

If a woman's vagina has a fishy smell, then these factors need to be diagnosed one-on-one, because these factors are the causes of the fishy smell in the vagina, so these factors cannot be ruled out. If the vagina has a fishy smell, then remember to clean your vagina more often and keep your vagina clean. At the same time, remember to change your underwear frequently.

There are several types of vaginal odor

1. Fishy smell

Some patients with vaginitis caused by anaerobic bacteria infection, Trichomonas infection or Haemophilus vaginalis infection often have a fishy odor in their leucorrhea.

2. Fishy smell

Vaginitis caused by Haemophilus vaginalis often causes the patient's leucorrhea to have a special fishy smell. Patients also experience symptoms such as vaginal burning, pain, itching, and vulvar moisture.

3. Foul odor

If the leucorrhea emits a foul odor, women must be vigilant because it may be related to serious infection or tumor of the reproductive tract. Malignant tumors of the reproductive tract, severe endometritis, and severe cervical erosion can all cause foul-smelling leucorrhea. If elderly women have foul-smelling leucorrhea that is bright red in color, this is often a sign of a malignant tumor.
