Every woman’s body has a natural scent, and it’s perfectly normal for it to change slightly throughout the month. But when that smell turns noticeably fishy, it often raises alarm bells. While it doesn’t always signal something serious, it’s worth paying attention. Understanding the possible causes can help you decide whether it’s a quick fix or something that needs a doctor’s care.
Why Vaginal Odor Happens
Let’s get one thing straight—your vagina is self-cleaning. It naturally maintains a delicate balance of bacteria and pH to keep things healthy. But sometimes that balance gets thrown off, and odor shows up as a result. A fishy smell doesn’t necessarily mean poor hygiene—it usually points to an underlying condition, trapped moisture, or simply everyday changes in your body.
Bacterial Vaginosis: The Most Common Culprit
The number one cause of a persistent fishy vaginal odor is bacterial vaginosis (BV). This happens when the “good” bacteria in your vagina are outnumbered by the “bad” bacteria. Symptoms include:
- A thin, grayish or white discharge
- A strong fishy odor, often stronger after sex
- Irritation or a mild burning sensation
BV is common and treatable, but it does require antibiotics prescribed by a healthcare provider. Ignoring it can increase the risk of other infections, so it’s best not to wait it out.
Trichomoniasis: An STI You Shouldn’t Ignore
Another possible cause is trichomoniasis, a sexually transmitted infection caused by a tiny parasite. Unlike BV, this condition won’t go away with better hygiene or home remedies—you’ll need medication. Common signs include yellow-green discharge, discomfort during sex, and that same fishy odor. If you’re sexually active and notice these symptoms, it’s important to get tested.

The Role of Hygiene and Lifestyle
Sometimes, the cause is much simpler. Wearing tight, non-breathable clothing or synthetic underwear can trap sweat and bacteria, creating unpleasant smells. Similarly, skipping showers after workouts or sitting in damp clothing for too long can lead to odor. Just like your armpits, the vaginal area can hold onto sweat and bacteria if it isn’t given room to breathe.
When a Forgotten Tampon Is the Problem
Believe it or not, one surprisingly common reason for a strong, foul odor is leaving a tampon in for too long. The smell can be so intense that people mistake it for a fishy odor. If this happens, remove the tampon immediately and see your doctor if the odor lingers or if you develop other symptoms like fever or unusual discharge.
How to Reduce and Prevent Vaginal Odor
The good news? In many cases, small lifestyle changes can help prevent odors from developing. Here are some simple but effective steps:
- Wash the external genital area with warm water and mild, unscented soap
- Avoid douching, which disrupts the natural bacterial balance
- Choose breathable cotton underwear and change it daily
- Use protection during sex to lower the risk of infections
- Skip heavily scented feminine products, which can irritate sensitive skin
Some women also find that probiotics, whether in food or supplements, support vaginal health by encouraging good bacteria. However, always check with your doctor before starting anything new.
When to See a Doctor
If the odor goes away after a shower or change of clothes, you probably don’t need to worry. But if it lingers, comes with itching, burning, unusual discharge, or pain, it’s time to book an appointment. Persistent fishy odor is often a sign of BV, trichomoniasis, or another condition that needs professional treatment.

Conclusion
A fishy odor “down there” isn’t something to ignore, but it’s not a reason to panic either. Sometimes it’s just a temporary imbalance or a hygiene slip, but other times it’s your body’s way of flagging an infection. By paying attention to the signs—whether it’s BV, trichomoniasis, or even a forgotten tampon—you can take action early and avoid complications. Remember: your body is always talking to you. The key is knowing when to listen and when to seek help.
