Why Does Bacterial Vaginosis (BV) Keep Coming Back?
If you've had bacterial vaginosis (BV) once, you're certainly not alone.
If you've had it several times...
You're probably asking a different question.
"Why does it keep coming back?"
For many women, the cycle becomes painfully familiar.
Treatment.
Relief.
A few weeks or months later...
The symptoms return.
After a while, it's easy to feel frustrated, embarrassed or even begin to wonder whether you'll ever be free of it.
The good news is this:
You're not imagining it.
Recurrent BV is recognised as a common problem.
The more difficult question is understanding why.
What Is BV?
Bacterial vaginosis occurs when the natural balance of bacteria in the vagina changes.
Normally, healthy bacteria (particularly lactobacilli) help maintain an acidic environment that protects against harmful bacteria.
When that balance is disrupted, other bacteria can multiply.
This can lead to symptoms such as:
A fishy vaginal odour
Thin grey or white discharge
Changes after sex
Sometimes mild irritation
Some women have no symptoms at all.
Why Does It Keep Coming Back?
Unfortunately, there isn't one simple answer.
Researchers believe several factors may contribute.
The Normal Bacteria Haven't Fully Recovered
Treatment removes the overgrowth of bacteria.
But it doesn't always restore the healthy bacteria that normally protect the vagina.
Without those protective bacteria, BV may return.
Individual Differences
Some women appear to be more prone to recurrent BV than others.
Researchers are still trying to understand exactly why.
Hormones, immune responses and the vaginal microbiome may all play a role.
Sexual Activity
BV is not considered a sexually transmitted infection.
However, sexual activity may influence the balance of vaginal bacteria in some people.
Researchers continue to study this relationship.
Smoking
Studies suggest that smoking may increase the risk of recurrent BV.
The reasons are not yet fully understood.
Other Factors
Researchers continue to investigate whether factors such as douching, certain hygiene products, hormonal changes and the vaginal microbiome influence recurrence.
The picture is complex.
Could Recurrent BV Mean Something Else?
Most of the time, recurrent BV is simply...
Recurrent BV.
It does not automatically mean there is another underlying condition.
However...
Persistent or repeatedly recurring symptoms deserve thoughtful review.
Sometimes healthcare professionals may decide that further assessment is appropriate.
This doesn't mean they expect to find something serious.
It means understanding why symptoms continue is an important part of good care.
My Story
For many years, I experienced recurrent BV.
Treatment helped.
But it kept returning.
At the time, I accepted it as one of those unfortunate things.
Looking back, I often wonder whether those recurring infections should have prompted a broader conversation.
Years later, I discovered that I had bilateral hydrosalpinx caused by endometriosis.
Can I say the BV caused it?
No.
Can I say recurrent BV always means endometriosis?
Absolutely not.
But I do wonder whether persistent symptoms—of any kind—deserve curiosity rather than simply repetition.
That question is one of the reasons I created this website.
When Should You Go Back?
If your BV keeps returning, don't feel embarrassed about going back to your healthcare professional.
Returning doesn't mean you've failed treatment.
It means the problem hasn't completely resolved.
You may wish to discuss:
whether the diagnosis is definitely BV,
whether longer treatment might be appropriate,
whether another condition could be contributing,
whether any further assessment is recommended.
Questions Worth Asking
If you've had recurrent BV, you might find these questions helpful:
Is this definitely bacterial vaginosis?
Why do you think it keeps coming back?
Are there any other possible explanations for my symptoms?
Would any further investigations be appropriate?
At what point should recurrent BV be reviewed differently?
Notice something?
None of those questions assume there's another diagnosis.
They simply encourage understanding.
Medical Words Made Simple
BV (Bacterial Vaginosis)
A common condition caused by an imbalance in the natural bacteria living in the vagina.
Microbiome
The community of bacteria and other tiny organisms that normally live in and on our bodies.
Many of these bacteria are helpful and play an important role in keeping us healthy.
I Wish Someone Had Explained...
For years, I thought recurrent BV was simply something I had to put up with.
I wish someone had explained that while recurrence is common, persistent symptoms are still worth talking about.
Not because they always mean something serious.
But because repeated symptoms deserve thoughtful conversations, just like any other recurring health problem.
Key Takeaways
Recurrent BV is common.
There isn't one single reason why it returns.
Most women with recurrent BV do not have another underlying condition.
Persistent or recurring symptoms deserve review.
Understanding why symptoms continue can help guide future care.
Hope
Living with recurrent BV can be exhausting.
It can affect confidence, relationships and day-to-day life.
If you're feeling frustrated, you're not alone.
The important thing to remember is this:
Recurring symptoms aren't something you simply have to ignore.
They deserve understanding.
And you deserve to feel heard.
A Gentle Reminder
Your body whispers before it screams.
Not every whisper means something serious.
But persistent symptoms deserve thoughtful conversations, informed questions and healthcare professionals who are willing to listen.
If something doesn't feel right, don't be afraid to ask again.
