Main causes and how to deal with bad smelling vaginal discharge

Main Causes

The presence of secretions through the vagina is normal due to the process of cell renewal. However, when discharge occurs excessively or frequently and is accompanied by a bad smell and other symptoms, such as pain when urinating or burning sensation in the vagina, for example, it can be a sign of vaginal imbalance and it is important to see your gynecologist.

The main causes of foul-smelling vaginal discharge are:

  • Bacterial vaginosis, which is an infection in the vagina usually caused by the bacterium Gardnerella sp. and can lead to the appearance of yellow or greyish discharge and a strong and unpleasant odor similar to rotten fish;
  • Trichomoniasis, is a vaginal infection caused by the parasite Trichomonas vaginalis and is characterized by the presence of yellowish-green discharge and strong odor;
  • Gonorrhea, is a sexually transmitted disease caused by the bacterium Neisseria gonorrhoeae and can lead to the appearance of brown discharge.

Candidiasis is one of the leading causes of vaginal infection and discharge in women, however it does not cause foul smelling discharge. See what can cause different types of vaginal discharge

Medication for vaginal discharge with foul smell

The remedy for foul smelling discharge depends on its causes, and the gynecologist may recommend the use of oral pills, vaginal ova and ointments to apply directly to the vagina.

It is important to note that the duration of treatment depends on the severity and type of discharge and your partner may also require treatment, and it is generally recommended by the gynecologist that close contact is avoided until the infection is cured.

Homemade treatment 

A good home treatment to reduce the discomfort caused by foul smelling discharge is a seat bath with guava leaves.


  • 30 g of guava leaves
  • 1 liter of water

Preparation method:

Boil 1 liter of water, turn off the fire after boiling, add the 30 g of guava leaves and close the pan for 3 to 5 minutes. Then you should strain to remove the leaves and put all the tea in a bowl.

When the tea is at a bearable temperature, sit down on the basin without clothing to do a seat bath, carefully washing the whole genital area until the water cools. Repeat the procedure 2 to 3 times a day.

In addition to the seat bath with guava leaves, some dietary changes such as consuming more fruits, vegetables, and natural yogurt may help to reduce foul-smelling discharge because they facilitate the rebalancing of the bacterial flora of the female genital organ.

If the stench persists after treatment with tea for a few days, it is important that a bacteriological examination of the discharge be performed by a gynecologist to identify the offending agent and treat the case accordingly.
