A vagina naturally has a mild scent, and that scent can change throughout the menstrual cycle, after exercise, or after sex. A strong or unpleasant odor, especially if it’s new or accompanied by other symptoms, can sometimes indicate a health issue.
4 Common Reasons for Vaginal Odor
1. Bacterial Vaginosis (BV)
BV occurs when the normal balance of bacteria in the vagina changes.
Common signs:
- A strong “fishy” odor
- Thin gray or white discharge
- Mild irritation or burning
BV is common and usually treatable with medication prescribed by a healthcare professional.
2. Poor Hygiene or Excess Sweat
Sweat, urine, menstrual blood, and natural secretions can accumulate around the vulva (the external genital area), especially during hot weather or after exercise.
What may help:
- Washing the external genital area with warm water
- Changing out of sweaty clothing promptly
- Wearing breathable cotton underwear
Avoid douching, as it can disrupt the vagina’s natural balance.
3. Forgotten Tampon or Other Foreign Object
A retained tampon can cause a very strong, unpleasant odor and may lead to infection.
Possible symptoms:
- Foul-smelling discharge
- Discomfort or irritation
- Unusual bleeding
If you suspect a tampon or other object is stuck, seek medical care promptly.
4. Sexually Transmitted Infections (STIs) or Other Infections
Some infections can cause changes in odor, discharge, or irritation.
Possible symptoms:
- Unusual discharge
- Burning during urination
- Pelvic pain
- Itching or irritation
Testing and treatment from a healthcare professional are important if an infection is suspected.
When to See a Doctor
Consider seeking medical advice if vaginal odor is accompanied by:
- Itching, burning, or irritation
- Green, yellow, or gray discharge
- Pelvic pain
- Fever
- Bleeding unrelated to your period
- A sudden, persistent, or very strong odor
Important Note
The vagina is self-cleaning, and a mild natural scent is normal. Products marketed to make the vagina smell like perfumes, flowers, or fruits are usually unnecessary and may sometimes cause irritation. If you’re concerned about a change in odor, a healthcare professional can help determine the cause and recommend appropriate treatment.
