Did you know your vagina has its own unique scent?

Every healthy vagina has a natural and unique smell. Interestingly, many women can recognize their own vaginal scent, a detail even their partners might not notice.

Understanding your vaginal smell is important because it helps you notice changes, like a shift to a fishy odor, which can signal a problem that needs attention.

No woman wants to experience a fishy vaginal smell. It’s not only uncomfortable, but it can affect your confidence, social life, and even fertility. That’s why understanding the causes and remedies for vaginal odors should be a priority.

This article will dive into what causes these smells and how they can be treated, so you can stay informed and take control of your vaginal health.

Causes of Fishy Vaginal Odor

Several factors can lead to an unpleasant vaginal odor. Let's explore some common causes:

Bacterial Vaginosis (BV)

Bacterial vaginosis occurs when harmful bacteria overgrow in the vagina, disrupting the natural balance between good and bad bacteria. The main symptom is a fishy smell, especially after sex. Other signs include itchiness, burning when urinating, and unusual discharge (gray or yellow).

Trichomoniasis

Trichomoniasis is a sexually transmitted infection caused by a parasite. This can result in a fishy odor along with a green, yellow, gray, or white discharge. Other symptoms include itching, pain during sex, and a burning sensation when urinating.

Pelvic Inflammatory Disease (PID)

Though less common, PID can cause a fishy smell if untreated infections spread from the vagina to the reproductive organs. Other signs include fever, pelvic pain, and bleeding after sex.

Excessive Sweating

Sweating in the pelvic area, particularly after exercise or stress, can cause a fishy smell. In rare cases, an underlying condition like trimethylaminuria may be the cause.

Forgotten Tampon

A forgotten tampon left in for too long can lead to toxic shock syndrome and a strong odor. Always remove tampons within the recommended time frame.

Diet

Your diet can influence vaginal odor. Foods like fish, garlic, and broccoli can contribute to a fishy smell due to their effects on your body's pH levels.

How Is the Cause of a Fishy Smell Diagnosed?

If you notice abnormal vaginal discharge and home remedies aren't working, it’s time to see a doctor. Self-diagnosis can make things worse, so it's crucial to seek professional advice.

Your healthcare provider will likely start with a physical exam, looking for abnormal discharge, inflammation, or other signs of infection. If necessary, they may perform additional tests, including vaginal fluid analysis or urinalysis, to pinpoint the cause.

Home Remedies for Foul-Smelling Discharge

If the fishy odor isn't severe, some simple remedies might help alleviate the smell:

Tea Tree Oil

Mix 3-4 drops of tea tree oil with water and use it to rinse the vaginal area. Tea tree oil has antibacterial and antifungal properties that can help eliminate the smell. Alternatively, dip a tampon in a mixture of olive oil and tea tree oil, and leave it in for one hour.

Baking Soda

Baking soda can help balance your pH levels. Mix half a cup of baking soda in a bath and soak for 30 minutes. You can also use it to rinse the vagina with water.

Garlic

Garlic has been used for centuries to fight infections. Wrap a fresh clove in cheesecloth, attach a string, and insert it overnight for its antibacterial benefits.

Guava Leaves

Boil 60 grams of guava leaves in 2 liters of water, let it cool, and then soak your lower body in the infusion. Guava leaves have natural antibiotic properties that can help reduce odor.

Fishy Vaginal Odor After Sex

A fishy smell after sex is often due to changes in vaginal pH. Semen and even saliva can temporarily affect your vagina’s acidic environment, leading to an altered scent. Anal sex without proper cleaning can also introduce bacteria, causing infection and odor.

Use protection and practice good hygiene to reduce the risk of post-sex odor.

Vaginal Odor Treatment: How to Get Rid of Fishy Vaginal Odor?

Medical Treatment

If bacterial vaginosis is the cause, your doctor may prescribe antibiotics. Over-the-counter antifungal creams can help with yeast infections, but if symptoms persist, seek further medical advice.

Practice Good Hygiene

Gently clean your vaginal area with water. Avoid harsh soaps that can disturb the natural pH balance. Wearing cotton underwear and avoiding tight clothing can help prevent excessive sweating.

Check Your Underwear

Switch to breathable fabrics like cotton, and avoid tight-fitting clothes that may trap moisture and bacteria.

Use a pH-Balancing Product

Over-the-counter pH products can help restore balance, but see a doctor if the issue persists.

Avoid Douching

Douching disrupts the natural bacterial balance in your vagina and can cause infections. It’s better to let your body clean itself naturally.

What’s the Most Common Cause of Fishy Vaginal Odor?

Bacterial vaginosis is the leading cause of fishy vaginal odor. While it’s not an STI, sexually active women are more likely to experience it. The condition is caused by an imbalance in the natural bacteria found in the vagina.

The Bottom Line

Your vagina’s unique scent can change, but if you experience a persistent fishy smell, don’t hesitate to seek treatment. Practicing good hygiene, maintaining a healthy diet, and knowing the signs of infection can help you stay on top of your vaginal health.
