Quick Answer

Bacterial vaginosis (BV) and yeast infections are two of the most common causes of vaginal symptoms, but they are not the same condition.

Because both can cause irritation, discharge, and discomfort, many women assume they have a yeast infection when the problem is actually BV—or vice versa.

The good news is that there are often clues that can help distinguish between the two.

Understanding the differences can help you get the right treatment sooner and avoid using medications that may not work for your condition.

Common Signs of BV:

• Thin discharge
• Gray or white discharge
• Fishy odor
• Symptoms often worsen after sex
• Mild irritation or no irritation

Common Signs of a Yeast Infection:

• Thick white discharge
• Cottage cheese-like appearance
• Intense itching
• Redness and irritation
• Burning sensation

Seek Medical Attention If You Experience:

• Severe pain
• Fever
• Pelvic pain
• Recurrent infections
• Symptoms during pregnancy
• Symptoms that continue worsening

Many women experience vaginal symptoms at some point in their lives.

When itching, discharge, odor, or irritation develops, it’s common to assume the cause is a yeast infection.

However, bacterial vaginosis is actually more common than many people realize.

Because the treatments for BV and yeast infections are different, recognizing the signs of each condition can help you choose the appropriate next steps.

What Is Bacterial Vaginosis (BV)?

Bacterial vaginosis occurs when the natural balance of bacteria in the vagina becomes disrupted.

The vagina normally contains a mix of healthy bacteria.

When certain bacteria begin to overgrow, BV can develop.

BV is not technically considered a sexually transmitted infection, but sexual activity can increase the risk.

Other factors that may contribute include:

• New sexual partners
• Multiple sexual partners
• Douching
• Changes in vaginal pH
• Smoking

BV is one of the most common causes of vaginal discharge among women of reproductive age.

What Is a Yeast Infection?

A yeast infection occurs when a fungus called Candida grows excessively.

Small amounts of Candida normally live in the body without causing problems.

However, when conditions allow the yeast to multiply, symptoms can develop.

Common factors that increase the risk of yeast infections include:

• Recent antibiotic use
• Pregnancy
• Diabetes
• Hormonal changes
• Weakened immune system
• Warm, moist environments

Yeast infections are extremely common and affect millions of women every year.

The Biggest Difference: Odor

One of the easiest ways to distinguish BV from a yeast infection is odor.

BV frequently causes a noticeable fishy smell.

Many women report that the odor becomes stronger after sexual intercourse.

A yeast infection typically does not cause a strong odor.

While some women may notice a mild smell, a fishy odor is much more suggestive of BV.

Although odor alone cannot provide a diagnosis, it is often an important clue.

The Biggest Difference: Discharge

The appearance of vaginal discharge can also provide useful information.

BV commonly causes:

• Thin discharge
• Gray discharge
• White discharge
• Watery consistency

Yeast infections more commonly cause:

• Thick white discharge
• Clumpy discharge
• Cottage cheese-like appearance

Not every woman experiences textbook symptoms, but discharge patterns often help distinguish between the two conditions.

The Biggest Difference: Itching and Irritation

Itching tends to be much more severe with yeast infections.

Women with yeast infections often describe:

• Intense itching
• Burning
• Redness
• Swelling
• Irritation around the vaginal opening

BV may cause mild irritation, but some women experience very little itching at all.

When severe itching is the primary symptom, a yeast infection is often more likely.

Why Self-Diagnosis Can Be Difficult

Although symptoms can provide clues, it isn’t always possible to accurately diagnose yourself.

Several other conditions may cause symptoms similar to BV or yeast infections, including:

• Sexually transmitted infections (STIs)
• Allergic reactions
• Vaginal irritation
• Hormonal changes
• Other vaginal infections

This is one reason recurring symptoms should not be ignored.

Repeatedly treating the wrong condition may delay appropriate care.

Summer Can Increase the Risk of Both Conditions

Many women notice more vaginal symptoms during summer months.

Warm weather, sweating, wet swimsuits, and prolonged moisture can create an environment that may increase the likelihood of irritation and infection.

Common summer triggers include:

• Staying in wet swimsuits
• Tight workout clothing
• Increased sweating
• Travel
• Changes in hygiene routines

Understanding these risk factors may help reduce future episodes.

When Symptoms Keep Coming Back

Occasional infections are common.

However, recurrent symptoms may indicate an underlying issue.

Frequent episodes may be associated with:

• Diabetes
• Hormonal changes
• Sexual health factors
• Antibiotic use
• Other medical conditions

Women experiencing repeated symptoms should consider medical evaluation rather than repeatedly self-treating.

Symptoms That Should Not Be Ignored

Most BV and yeast infections are not medical emergencies.

However, some symptoms warrant prompt evaluation.

Seek Medical Evaluation If You Develop:

• Fever
• Pelvic pain
• Severe abdominal pain
• Symptoms during pregnancy
• Recurrent infections
• Bloody discharge
• Symptoms that continue worsening

These symptoms may indicate a more serious condition.

What Is Usually Normal

Common Symptoms of BV

• Thin discharge
• Fishy odor
• Mild irritation
• Gray or white discharge

Common Symptoms of a Yeast Infection

• Thick white discharge
• Itching
• Burning
• Redness
• Irritation

These symptoms often improve with appropriate treatment.

What Is More Concerning

Seek Medical Evaluation Promptly If You Develop:

• Fever
• Pelvic pain
• Severe pain
• Recurrent infections
• Symptoms during pregnancy
• Unexplained bleeding
• Symptoms that worsen despite treatment

These symptoms should not be ignored.

FAQ

Is BV a sexually transmitted infection?

No. BV is not considered a sexually transmitted infection, although sexual activity may increase the risk.

Can BV go away on its own?

Some cases may improve without treatment, but many require prescription medication to fully resolve.

What does yeast infection discharge look like?

Yeast infections often cause thick, white, clumpy discharge that may resemble cottage cheese.

Why does BV cause odor?

BV occurs when certain bacteria overgrow, producing compounds that create a fishy smell.

Can I have BV and a yeast infection at the same time?

Yes. It is possible to have both conditions simultaneously.

Bacterial vaginosis and yeast infections are common, but they are different conditions with different causes and treatments.

BV is often associated with a fishy odor and thin discharge, while yeast infections are more commonly linked to itching, irritation, and thick white discharge.
