Many women experience an unpleasant, fishy odor coming from their intimate area at some point in their lives. While this can feel embarrassing or concerning, it isn’t always a sign of a serious problem. In fact, a mild vaginal odor is normal and varies from person to person. Sometimes, a temporary change in scent can occur for no specific reason and may resolve on its own.

Often, something as simple as changing into clean, breathable underwear after a shower or bath is enough to restore your natural scent. Proper hygiene, especially after sweating or during your menstrual cycle, plays an important role in maintaining a healthy vaginal environment.

However, if the fishy odor persists despite good hygiene or is accompanied by other unusual symptoms such as itching, burning, pain, or abnormal discharge, it may be time to consult a gynecologist. These signs could point to an underlying health condition that needs medical attention.

Bacterial Vaginosis: The Most Common Cause

One of the leading causes of a strong fishy smell is bacterial vaginosis (BV). This condition occurs when there is an imbalance in the natural bacteria found in the vagina. Instead of healthy bacteria (lactobacilli) dominating, other types of bacteria multiply excessively.

Common symptoms of BV include:

• A thin, gray or white vaginal discharge

• A strong fishy odor, which may become more noticeable after intercourse

• Vaginal itching or a mild burning sensation during urination

Bacterial vaginosis is not sexually transmitted, but sexual activity can influence its development. Fortunately, BV can be effectively treated with a course of antibiotics prescribed by your healthcare provider.

Other Potential Causes

1. Poor Hygiene and Tight Clothing
Wearing tight, non-breathable clothing—especially synthetic underwear—can trap moisture and sweat, creating an environment where bacteria thrive. Lack of regular washing or not changing underwear after workouts can also contribute to odor.

2. Trichomoniasis
This is a sexually transmitted infection (STI) caused by a parasite. Trichomoniasis often leads to a foul-smelling vaginal discharge, sometimes described as musty or fishy. Other symptoms may include genital redness, burning, and discomfort during urination or sex. Unlike BV, trichomoniasis is contagious and requires medical treatment—home remedies won’t help here.

3. Forgotten Tampons
A surprisingly common cause of a strong, rotten odor—often mistaken for a fishy smell—is a forgotten tampon. If left inside the body too long, tampons can begin to decompose and lead to a powerful, offensive smell. In this case, removing the tampon and seeking medical attention if irritation occurs is important.

When Should You Worry?

If the odor lasts for more than a few days, becomes stronger, or is accompanied by pain, itching, or unusual discharge, it’s a good idea to get a professional evaluation. Conditions like BV, trichomoniasis, or even yeast infections should be diagnosed and treated properly. Ignoring symptoms can lead to complications or recurring infections.

Preventive Tips to Keep Things Fresh

Maintaining vaginal health is mostly about balance and gentle care. Here are some practical steps you can take:

• Practice proper hygiene: Wash the external genital area daily with warm water. Mild, unscented soap can be used, but avoid douching or using strong chemicals inside the vagina.

• Wear breathable fabrics: Opt for cotton underwear and avoid tight-fitting clothes that can trap moisture.

• Change underwear regularly, especially after exercise or sweating.

• Use protection during sex: This helps reduce the risk of STIs.

• Avoid scented feminine products: Sprays, wipes, and perfumed soaps can irritate the vaginal area and disrupt its natural pH.

• Stay hydrated and eat a balanced diet: What you eat and drink can affect your body’s natural odors too.

In Summary

A fishy odor from your intimate area isn’t necessarily cause for alarm. In many cases, it’s temporary and can be managed with good hygiene and proper self-care. However, if it persists or comes with other symptoms, don’t hesitate to seek medical advice. Your gynecologist can help determine the cause and recommend the best course of treatment.

Taking care of your intimate health not only improves comfort and confidence, but also helps prevent more serious health issues in the future.
