How to Eliminate Fishy Odor from BV Quickly and Regain Confidence
Let’s be real for a moment—there’s nothing more frustrating (and honestly, embarrassing) than noticing a fishy vaginal odor out of the blue. I’ve been there. You start googling things like “why do I smell like fish” or “how to get rid of BV smell fast” and end up feeling more overwhelmed than helped. That unmistakable scent, often the hallmark of bacterial vaginosis (BV), isn’t just a nuisance—it messes with your confidence, intimacy, and peace of mind. So if you’re looking for real, fast, and effective solutions on how to eliminate fishy odor from BV quickly, let’s dig into the root of it—and the fixes that actually work.
Understanding the Cause: What Triggers the Fishy Odor in BV?
The fishy odor associated with BV is caused by an imbalance in the natural bacteria in the vagina. Normally, the vagina maintains a healthy mix of bacteria, with Lactobacilli playing the lead role in keeping the pH low and warding off harmful invaders. But when this balance tips—say due to antibiotics, over-washing, or even stress—anaerobic bacteria take over, leading to that unmistakable smell.
Some of the most common triggers I’ve personally seen (and yes, experienced) include:
- Overuse of scented soaps or feminine washes
- Unprotected sex with new or multiple partners
- Hormonal fluctuations around your cycle
- Heavy sweating or wearing synthetic underwear for long hours
If you’re curious about specific habits that could be making things worse, this breakdown on hygiene habits and BV dives deeper.
Step One: Start With the Right Diagnosis
You’d be surprised how often people mistake BV for a yeast infection. I used to think any vaginal discomfort meant “yeast,” until a simple home test showed otherwise. BV doesn’t usually come with itching or cottage cheese-like discharge—instead, you’re looking at thin, grey-white discharge and a strong fishy odor. That’s your clue.
There are reliable at-home tests that detect changes in vaginal pH, but if you’re unsure, it’s always best to confirm with a professional. Misdiagnosis leads to mistreatment, which makes symptoms linger longer than necessary.
Medical Treatments That Act Fast
If you’re in a time crunch and need the odor gone ASAP, prescription medication is still the gold standard. Metronidazole or Clindamycin—usually in gel or oral form—can start improving symptoms within 24-48 hours.
I once had a wedding to attend in 3 days—yes, three—and I literally begged my doctor for a quick solution. She prescribed Metronidazole gel, and by day two, the odor was gone, and my confidence was back. You can learn more about these options here.
If you’re pregnant or have sensitivities, options like BV-safe treatments during pregnancy may be more appropriate. Always talk to your OB-GYN.
Fast-Acting Natural Remedies That Actually Work
If prescription meds aren’t your vibe, or you’re waiting for a doctor’s appointment, there are natural remedies that can help mask the odor and restore balance fast:
- Probiotic Supplements: I swear by these. Look for strains like Lactobacillus rhamnosus and reuteri. They help repopulate good bacteria.
- Yogurt: Not just for breakfast. Applying plain, unsweetened yogurt directly can cool inflammation and replenish flora. It’s weird, but it works.
- Apple Cider Vinegar Soaks: Add a cup to your bath for 15 minutes. It helps balance pH quickly. Just don’t douche with it, please.
We break down all these options in this complete BV natural remedy guide, with do’s and don’ts for each one.
What to Avoid When the Odor Hits
When you’re desperate to smell fresh again, the biggest temptation is to go overboard with cleaning. Trust me, I used to scrub like I was prepping for surgery. But over-washing, douching, or using antiseptic wipes only strip away the good bacteria and make things worse.
Avoid these common mistakes:
- Douching or using hydrogen peroxide (nope, it’s not safe)
- Using scented tampons or pads
- Wearing non-breathable underwear or tight leggings all day
- Skipping meals or going low-carb (your microbiome needs good fuel)
There’s a great breakdown on why douching is a myth and how to keep your pH in check without going nuclear on your body.
Use Diet as a Weapon Against the Smell
Okay, this one surprised me. After dealing with recurring BV for months, a nutritionist friend suggested cutting back on sugar and adding fermented foods like kimchi and kefir to my diet. Within two weeks, the odor was gone—and stayed gone.
Foods that help:
- Greek yogurt (plain, full-fat)
- Leafy greens, especially spinach and kale
- Fermented stuff—miso, kimchi, sauerkraut
- Garlic (it’s antimicrobial—just be sure your partner doesn’t mind)

Upgrade Your Underwear Game for Long-Term Odor Control
I used to roll my eyes at “change your underwear fabric” tips—until I swapped out my synthetic favorites for good old breathable cotton. It’s not just a comfort thing. Cotton lets your skin breathe and helps reduce moisture buildup that fuels bacterial overgrowth.
If you’ve been dealing with recurring odor or stubborn BV symptoms, small fabric choices make a big difference. Skip the shapewear, thongs, and tight leggings if you’re prone to flare-ups. Want to nerd out on the science? This underwear guide breaks it all down.
Address Sexual Triggers Without Shame
Here’s something we don’t talk about enough: sex can absolutely throw off your vaginal balance. I didn’t realize that unprotected sex—even with a monogamous partner—was one of my biggest BV triggers. Semen is alkaline, and after sex, your pH spikes. Boom. Odor.
You don’t have to abstain (please don’t), but you can:
- Use condoms regularly
- Gently rinse with plain water (no soap!) after sex
- Avoid lube with harsh ingredients—opt for aloe- or water-based options

Handle Recurrent BV Like a Pro
Recurring BV is the ultimate buzzkill. You think it’s gone, and then bam—it’s back. If the fishy smell keeps creeping in despite treatment, you’re not alone. Nearly 50% of women deal with recurrence within a year, according to research on ncbi.nlm.nih.gov.
What’s worked for me (and thousands of others):
- Regular use of probiotics (both oral and vaginal)
- Avoiding sugar and alcohol during your cycle
- Tracking patterns with a simple journal or app

How to Smell Fresh—Even When Treating BV
When I had BV, even after starting treatment, I was obsessed with staying fresh. What helped me feel less self-conscious during the healing phase:
- Changing underwear midday (especially during hot days or after workouts)
- Using unscented, pH-balanced feminine wipes—very gently
- Letting everything breathe at night—yes, sleep commando
The fishy odor often fades within a couple days of treatment, but lifestyle support keeps things comfortable while your body restores its natural balance.
Know When to Ask for Help
I get it—it’s uncomfortable to bring up vaginal odor at the doctor’s office. But sometimes it’s necessary. If you’ve tried everything, followed all the advice, and the smell persists, it might not be BV. Or you might have a co-infection.
Red flags that warrant medical attention:
- Strong, persistent odor after a full course of treatment
- Burning, itching, or unusual sores
- Recurrent BV more than 3 times in a year
Also worth noting: BV vs. yeast infection symptoms can overlap, so don’t try to diagnose yourself blindly every time.
Protect Your pH Beyond the Infection
Once the smell is gone and treatment is complete, you want to keep it that way. Here’s what I’ve done to maintain that sweet balance:
- Weekly probiotic suppositories: quick, easy, and effective
- Switching to non-toxic period products: tampons and pads with no dyes or fragrances
- Drinking more water: basic but often overlooked
Also—be picky about what goes near your lady parts. Everything from laundry detergent to body wash matters. A gentle, fragrance-free routine has been key for me.
