FAQ About Vaginal Odor
1. What is Considered Normal Vaginal Odor?
The vagina naturally contains a diverse community of bacteria, known as the vaginal flora, which plays a vital role in maintaining a healthy balance. This bacterial ecosystem produces cervical mucus, which inherently has a scent. Changes in odor can occur throughout your menstrual cycle as the pH levels in your vagina fluctuate.
Dr. Rosén explains that normal vaginal odor can range from slightly tangy or sour to a more metallic scent around or after your period. Generally, if you feel well and the vaginal odor or discharge is not unusual for you, there’s no cause for concern.
2. 8 Common Causes of Vaginal Odor and When to See a Doctor
While some vaginal odor is normal, a strong or unpleasant smell could indicate an underlying issue. Here are eight common causes of vaginal odor and when it’s important to seek medical advice:
2.1. Bacterial Vaginosis (BV)
Vaginal Odor: Fishy
Bacterial vaginosis (BV) is a common condition caused by an imbalance in the vaginal flora, affecting 15% to 50% of women of reproductive age. The primary symptom is often a fishy odor, which may progress to a frothy, gray, or greenish discharge. Itchiness and swelling may also occur.
Treatment: If BV symptoms don’t clear up on their own, a doctor can prescribe antiseptics or antibiotics. Recurrence is common after antibiotic treatment, but probiotics may help. It is also important to consider that your sexual partner may be the cause of the infection, so it is important to discuss hygiene and the use of condoms.
When to See a Doctor: If you experience these symptoms, consult a doctor to rule out any underlying conditions that may require treatment, especially if you’re pregnant, as there’s an increased risk of premature labor.
Key Facts about Bacterial Vaginosis (BV)
| Fact | Description |
|---|---|
| Prevalence | Affects 15-50% of women of reproductive age |
| Cause | Imbalance of vaginal flora |
| Symptoms | Fishy odor, frothy gray/greenish discharge, itching, swelling |
| Treatment | Antiseptics or antibiotics prescribed by a doctor |
| Recurrence | Common after antibiotic treatment; probiotics may help |
| Partner Involvement | Sexual partners may contribute to infection; hygiene and condom use recommended. Partner may also need antibiotics in recurring infections. |
2.2. Trichomoniasis
Vaginal Odor: Pungent and Fishy, Similar to BV
Trichomoniasis is a sexually transmitted infection (STI) caused by a parasite. Many people experience subtle symptoms, such as a yellowish-green vaginal discharge with an unpleasant smell, and the vulva can be slightly red and itchy.
Treatment: A course of antibiotics usually clears it up.
When to See a Doctor: If you suspect you have trichomoniasis, it’s important to see a doctor for diagnosis and treatment.
Key Facts about Trichomoniasis
| Fact | Description |
|---|---|
| Type | Sexually Transmitted Infection (STI) |
| Cause | Parasitic disease |
| Symptoms | Yellowish-green discharge, unpleasant smell, red and itchy vulva |
| Treatment | Antibiotics |
| Prevalence | Most common non-viral STI worldwide |
2.3. Toxic Shock Syndrome (TSS)
Vaginal Odor: Very Unpleasant, but Odor is Generally a Minor Symptom
Toxic shock syndrome (TSS) is a rare but serious condition often associated with the use of high-absorbency tampons. If bacteria enter your system, you can become very sick quickly. Symptoms include high fever, blood pressure changes, rash, diarrhea or vomiting, and feeling faint.
Treatment: If you experience these symptoms, seek immediate medical attention.
When to See a Doctor: Go straight to the emergency room if you suspect TSS.
Key Facts about Toxic Shock Syndrome (TSS)
| Fact | Description |
|---|---|
| Rarity | Very rare illness |
| Cause | Bacteria entering the system, often linked to high-absorbency tampons |
| Symptoms | High fever, blood pressure changes, rash, diarrhea, vomiting, feeling faint |
| Severity | Very serious; requires immediate medical attention |
| Action Required | Go to the emergency room immediately if you experience these symptoms |
2.4. A Tampon You’ve Forgotten to Remove
Vaginal Odor: Very Unpleasant
A forgotten tampon can cause a strong, offensive odor. The smell will worsen quickly and be extremely obvious.
Treatment: Remove the tampon immediately. If you have difficulty removing it or notice any signs of infection, see a doctor.
When to See a Doctor: If you can’t remove the tampon yourself or suspect an infection.
Key Facts about Retained Tampon
| Fact | Description |
|---|---|
| Odor | Extremely unpleasant and offensive |
| Cause | Tampon left in vagina for an extended period |
| Action | Remove the tampon immediately |
| Medical Attention | See a doctor if you cannot remove it or suspect an infection |
2.5. Vaginal Thrush (Yeast Infection)
Vaginal Odor: Yeasty
Vaginal yeast infections like thrush are very common and typically cause itching, burning, and changes to vaginal discharge, which can become lumpy and white, similar to curdled milk. The discharge usually isn’t very smelly.
Treatment: Over-the-counter antifungal creams or suppositories can often treat thrush.
When to See a Doctor: If your thrush symptoms are pronounced with a bad smell, see a doctor to rule out any underlying conditions.
Key Facts about Vaginal Thrush
| Fact | Description |
|---|---|
| Prevalence | Very common |
| Symptoms | Itching, burning, white lumpy discharge |
| Odor | Usually not very smelly |
| Treatment | Over-the-counter antifungal creams or suppositories |
| Medical Attention | See a doctor if symptoms are severe or accompanied by a foul smell |
2.6. Hormonal Changes
Vaginal Odor: Individual
Hormonal changes, such as those that occur during menstruation, menopause, and pregnancy, can affect the smell of your cervical mucus. During menopause and in the post-menopausal years, the smell can change. Pregnancy can also change the cervical mucus; you may have more discharge, or sometimes it’s thicker or thinner, but it shouldn’t be smelly.
Treatment: Usually, no specific treatment is needed. However, maintaining good hygiene can help minimize odor.
When to See a Doctor: If you’re pregnant and have a foul-smelling discharge, speak to a doctor or midwife.
Key Facts about Hormonal Changes
| Fact | Description |
|---|---|
| Cause | Hormonal fluctuations |
| Examples | Menstruation, menopause, pregnancy |
| Odor Change | Can alter the smell of cervical mucus |
| Pregnancy | May increase discharge, but discharge should not be foul-smelling |
| Medical Advice | Consult a doctor if pregnant and experiencing foul-smelling discharge |
2.7. UTIs and Other Urinary Issues
Vaginal Odor: Ammonia
An ammonia-like vaginal odor might indicate urine involvement, possibly due to a urinary tract infection (UTI). This is more likely if a UTI is left untreated and you might be leaking. An untreated infection will also cause a fever, and the smell will be quite distinct and sickly.
Treatment: UTIs are typically treated with antibiotics.
When to See a Doctor: If you suspect a UTI, see a doctor for diagnosis and treatment. Also, an ammonia-like smell can be a sign of an existing incontinence issue that you’re unaware of; a doctor or gynecologist can advise on treatment options.
Key Facts about UTIs and Urinary Issues
| Fact | Description |
|---|---|
| Odor | Ammonia-like |
| Possible Cause | Urinary Tract Infection (UTI) or incontinence |
| UTI Symptoms | Untreated infection can cause fever and a distinct smell |
| Incontinence | Can cause an ammonia-like smell if unaware of the issue |
| Treatment | UTIs typically treated with antibiotics; incontinence can be managed with medical advice |
| Medical Advice | Consult a doctor if you suspect a UTI or have incontinence issues |
2.8. Gynecological Cancers
Vaginal Odor: Metallic and Sickly
In rare cases, a foul-smelling discharge can be a symptom of cervical or uterine cancer. However, discharge and vaginal odor are unlikely to be the only or first symptoms. You might experience bleeding during intercourse or occasional spotting that becomes more regular. The smell will be a little metallic and very different from the fishy or rotten smells of BV or a forgotten tampon.
Treatment: If you experience unusual bleeding, talk to a doctor.
When to See a Doctor: Always consult a doctor if you experience unusual bleeding.
Key Facts about Gynecological Cancers
| Fact | Description |
|---|---|
| Association | In rare cases, can be associated with cervical or uterine cancer |
| Odor | Metallic and sickly |
| Other Symptoms | Unusual bleeding, spotting |
| Note | Foul-smelling discharge unlikely to be the only or first symptom |
| Medical Advice | Always consult a doctor if you experience unusual bleeding |
3. Can STIs Cause Vaginal Odor?
STIs like chlamydia and gonorrhea rarely change the smell of the cervical mucus but can cause other symptoms like pain when peeing. If you notice a smell, it might be that you’ve also got bacterial vaginosis. If in doubt, talk to a doctor for advice.
Common STIs and Their Symptoms
| STI | Common Symptoms | Effect on Vaginal Odor |
|---|---|---|
| Chlamydia | Painful urination, abdominal pain, unusual discharge | Rarely changes vaginal odor |
| Gonorrhea | Painful urination, increased vaginal discharge, abdominal pain | Rarely changes vaginal odor |
| Trichomoniasis | Yellowish-green vaginal discharge with an unpleasant smell, vulvar redness, itching | Pungent and fishy, similar to BV |
| BV | Fishy odor, frothy gray/greenish discharge, itching, swelling | Fishy |
4. How to Get Rid of Vaginal Odor
Many people concerned about vaginal odor seek the right washing routine or best feminine wash for odor. Like any part of the body that gets sweaty, the area around the vulva can get smelly. However, soaps can disturb the natural balance of the vaginal bacterial flora and possibly increase the risk of bacterial vaginosis. Douching – a method of washing out or rinsing the vagina – can do the same.
The recommended way to wash down there is with nothing but water, and avoid perfumed sanitary pads or vaginal deodorants.
If you’re very dry due to breastfeeding, vaginal atrophy (the thinning, drying, and inflammation of the vaginal walls, often caused by lower estrogen levels) or a recent infection, you can use vaginal moisturizers – but nothing with perfume.
Do’s and Don’ts for Maintaining Vaginal Hygiene
| Do’s | Don’ts |
|---|---|
| Wash with water only | Use soaps or perfumed washes |
| Maintain good personal hygiene | Douche |
| Use unscented products | Use perfumed sanitary pads or vaginal deodorants |
| Consider vaginal moisturizers if dry | Use perfumed moisturizers |
5. When to Speak to a Doctor About Vaginal Odor
It’s important to recognize if the smell is abnormal for you.
Making simple lifestyle changes like using just water to wash down there and avoiding perfumed products is a good place to start. There are plenty of home remedies for vaginal odor too, like eating pineapple or drinking pineapple juice regularly, but these may not work for everyone.
But if the smell seems to be getting worse or you have other symptoms too, speak to a doctor.
When to Consult a Doctor About Vaginal Odor
| Situation | Recommendation |
|---|---|
| Smell is abnormal for you | Recognize and monitor |
| Smell is getting worse | Speak to a doctor |
| Experiencing other symptoms (discharge, itching) | Seek medical advice |
| Suspect an infection or STI | Consult a healthcare professional |
