Treatment depends on the severity and recurrence of symptoms.
Antifungal medications may be available as vaginal creams, suppositories, or oral medication.
However, recurring or persistent symptoms should be assessed rather than repeatedly self-treated.
Not every case of itching or discharge is caused by yeast.
7. Trichomoniasis and Other Sexually Transmitted Infections
Some sexually transmitted infections can cause changes in vaginal odor and discharge.
One example is trichomoniasis, an infection caused by a microscopic parasite called Trichomonas vaginalis.
Some women experience:
-
Yellow-green or grayish discharge
-
An unpleasant or unusual odor
-
Genital irritation
-
Burning during urination
-
Discomfort during sex
However, many people with trichomoniasis have no noticeable symptoms.
Other sexually transmitted infections, including gonorrhea and chlamydia, may also cause abnormal discharge or discomfort.
They do not always produce a distinctive smell.
This is why a person cannot determine whether they have an STI simply by checking the odor of vaginal discharge.
Testing is important when there has been possible exposure, a new sexual partner, unprotected sex, or unexplained symptoms.
If an STI is diagnosed, sexual partners may also need testing and treatment.
Avoid sexual contact until you have received appropriate medical advice and completed the recommended treatment.
8. A Forgotten Tampon or Other Foreign Object
A less common but important cause of strong vaginal odor is a retained foreign object.
A tampon that has been left inside the vagina for too long can develop a very unpleasant smell.
Other possible retained objects include pieces of condoms or other materials.
Symptoms may include:
-
Strong, foul-smelling discharge
-
Unusual vaginal bleeding
-
Pelvic discomfort
-
Irritation
-
Fever in some cases
If you suspect that a tampon or another object is retained, seek medical help to have it removed safely.
Do not insert tools or sharp objects into the vagina to try to retrieve it.
A retained tampon should not be ignored, especially if fever, rash, dizziness, vomiting, or feeling severely unwell develops.
These symptoms require urgent medical attention.
9. Urinary Leakage Can Be Mistaken for Vaginal Odor
Not every unusual smell around the genital area comes from the vagina.
Urine leakage can contribute to a strong ammonia-like scent, particularly when small amounts remain on underwear or skin.
This may occur with urinary incontinence, bladder problems, or difficulty fully emptying the bladder.
Urinary tract infections can also change the smell of urine.
Other symptoms may include:
-
Burning when urinating
-
Frequent urination
-
Sudden urgency
-
Cloudy urine
-
Lower abdominal discomfort
A urinary tract infection does not necessarily cause vaginal odor.
However, because the urinary and reproductive systems are located close together, people may sometimes have difficulty identifying where a smell is coming from.
If you have urinary symptoms, a urine test may help identify the cause.
Fever, chills, back or side pain, vomiting, or feeling very unwell may indicate a more serious infection and should be assessed promptly.
How to Tell Whether the Smell Is Coming From the Vagina or the Vulva
The vagina and vulva are not the same thing.
The vagina is the internal muscular canal.
The vulva refers to the external genital structures, including the labia and the area surrounding the vaginal opening.
This distinction matters because odor can come from either area.
For example:
-
Vaginal discharge may have a different scent because of changes in the vaginal microbiome.
-
Sweat can accumulate around the external genital area.
-
Urine may remain on the skin or underwear.
-
Menstrual blood can temporarily change the overall scent.
-
Skin irritation or infection may affect the external vulva.
You do not need to insert anything into the vagina to investigate the source of an odor.
Pay attention to discharge, external irritation, urinary symptoms, and whether the change occurs at a particular time in your menstrual cycle.
If you are unsure, a healthcare professional can examine the area and recommend appropriate testing.
Why You Should Avoid Vaginal Douching
One of the most common mistakes people make when trying to eliminate vaginal odor is washing inside the vagina.
Douching involves introducing water or other solutions into the vaginal canal.
Products may contain fragrances, antiseptics, vinegar, or other ingredients marketed as cleansing treatments.
The problem is that the vagina is not an area that needs internal washing.
It has its own natural mechanisms for maintaining a healthy environment.
Douching may disturb the vaginal microbiome and is associated with bacterial vaginosis and other reproductive health concerns.
It can also irritate delicate tissues.
A temporary feeling of cleanliness does not mean the underlying problem has been solved.
If an unusual smell is caused by an infection, douching will not reliably treat it.
In some cases, it may make the imbalance worse.
The simplest approach is usually the safest: clean the external vulva gently and leave the inside of the vagina alone.
Are Feminine Washes Necessary?
Many products are marketed specifically for intimate hygiene.
Some are fragranced, while others claim to maintain a particular vaginal pH.
The reality is that most women do not need special products to keep the vagina healthy.
