Vaginal itching and irritation can stem from either Bacterial Vaginosis (BV) or a yeast infection, but these conditions are distinctly different. BV is caused by an imbalance of vaginal bacteria leading to a thin, fishy-smelling discharge, while yeast infections result from an overgrowth of Candida fungus, often causing thick, odorless discharge and intense itching.
In this article, you’ll find out:
- The specific symptoms of each condition
- Key risk factors and causes
- Effective treatments and prevention methods
Understanding these differences ensures the right approach to treatment and relief.
What Is Bacterial Vaginosis (BV)?
Bacterial Vaginosis (BV) arises from an imbalance in the natural bacterial community within the vagina. Normally, bacteria like Lactobacillus maintain a healthy vaginal environment by producing lactic acid, which keeps the pH in check. However, when there’s an overgrowth of harmful bacteria such as Gardnerella vaginalis and Atopobium vaginae, it disrupts this balance, leading to BV.
Major Causes of BV
Various factors can cause this bacterial imbalance:
- Sexual Activity: Engaging in sexual activities with new or multiple partners increases the likelihood of introducing different bacterial strains to the vaginal flora.
- Douching: This practice disrupts the natural environment of the vagina, washing away both harmful and beneficial bacteria.
- Use of Intrauterine Devices (IUDs): Some studies suggest that IUDs can alter the vaginal flora, making it conducive for bacterial overgrowth.
Contributing Factors
Several elements can contribute to the development of BV:
- Hormonal Changes: Fluctuations in hormone levels during menstruation, pregnancy, or menopause can affect the vaginal microbiome.
- Antibiotics: Using antibiotics for other infections can inadvertently kill beneficial bacteria, creating an imbalance.
- Diet and Lifestyle: Diets high in sugar or poor overall health can indirectly create an environment where harmful bacteria thrive.

A yeast infection, medically referred to as Candidiasis, is an overgrowth of the Candida fungus. Typically, Candida albicans is the most common culprit. While Candida exists naturally in the vagina, an imbalance can lead to symptoms like itching, swelling, and discharge.
Key Contributing Factors
Several factors can lead to a yeast infection:
- Antibiotics Use: Antibiotics can kill not only the harmful bacteria they’re targeting but also the beneficial bacteria in the vagina, making room for yeast to grow.
- Hormonal Changes: Just like with BV, hormonal fluctuations can make the vaginal environment more susceptible to yeast overgrowth.
- Uncontrolled Diabetes: High blood sugar levels can fuel yeast growth.
- Weakened Immune System: Health conditions or medications that weaken immune function can make it easier for yeast to overgrow.
Risk Factors for Yeast Infections
Different circumstances make you more likely to develop a yeast infection:
- High Estrogen Levels: Women using high-estrogen contraceptives or undergoing hormone therapy are more prone to yeast infections.
- Wearing Tight Clothing: Non-breathable fabrics can trap moisture, providing a perfect environment for yeast to grow.
- Lifestyle and Diet: Diets high in refined sugars and carbohydrates can encourage yeast growth.
Symptoms of BV vs. Yeast Infection
Understanding the symptoms of BV and yeast infections can help you determine which condition you might be experiencing.
Symptoms of BV
BV’s symptoms are often more subtle compared to yeast infections:
- Discharge: A thin, watery, grayish-white discharge is common.
- Odor: The discharge typically has a fishy odor, most noticeable after intercourse.
- Itching and Irritation: Mild in some cases, though often less pronounced.
Symptoms of Yeast Infections
Yeast infections usually present more severe symptoms:
- Discharge: The discharge is thick, white, and resembles cottage cheese.
- Odor: Usually odorless or mildly yeast-like.
- Itching and Irritation: Intense itching and a burning sensation in the vaginal area.
- Swelling and Redness: The vulva may appear swollen and red.
Comparing Symptom Severity
While both conditions cause discomfort:
- BV Symptoms: Less likely to cause severe itching or redness but more likely to have a distinct fishy smell.
- Yeast Infection Symptoms: More likely to cause severe itching, burning, and redness but usually odorless.
Causes and Risk Factors
Both BV and yeast infections have overlapping and distinct causes and risk factors.
Causes of BV
BV mainly results from an imbalance in the vaginal bacterial community. Factors that may trigger this condition include:
- Sexual Activity Patterns: Multiple or new sexual partners can introduce unfamiliar bacteria.
- Vaginal Hygiene Practices: Practices like douching can disturb the natural bacterial balance.
Risk Factors for BV
Risk factors for BV include:
- Smoking: Smoking can negatively impact vaginal health.
- Unbalanced Diet: Poor nutrition can indirectly affect bacterial balance.
Causes of Yeast Infections
Yeast infections are primarily caused by the overgrowth of Candida fungi. This overgrowth can result from:
- Antibiotics: Antibiotics can disrupt the bacterial balance, making it easier for yeast to proliferate.
- Immune System Issues: Conditions that weaken the immune system can make one more susceptible to yeast overgrowth.
Risk Factors for Yeast Infections
Factors that increase the risk of yeast infections include:
- Hormonal Changes: Pregnancy, contraceptive use, and hormone therapy.
- Diet: High sugar intake can promote yeast growth.
Shared Risk Factors
Some risk factors are common to both BV and yeast infections:
- Hormonal Fluctuations: Both conditions can be triggered by changes in hormone levels.
- Antibiotic Use: Antibiotics can disrupt the balance of both bacteria and yeast.
- Health and Hygiene: Poor health and inadequate hygiene practices affect both conditions.
Diagnosis: How to Tell If It’s BV or a Yeast Infection
Proper diagnosis is crucial for effective treatment. You can differentiate between BV and yeast infections through specific diagnostic procedures.
Medical Examinations for BV
For diagnosing BV, your healthcare provider will typically:
- Pelvic Exam: Your provider will examine your vagina for signs of infection.
- Discharge Test: A sample of vaginal discharge will be collected and examined under a microscope.
- pH Test: The vaginal pH will be measured; a pH higher than 4.5 often indicates BV.
Lab Tests for Yeast Infections
To diagnose yeast infections, healthcare providers generally conduct:
- Pelvic Exam: This helps identify physical symptoms like swelling or discharge.
- Microscopic Analysis: A small sample of the discharge is examined under a microscope to detect yeast cells.
Diagnostic Tools
In general, diagnostic tools include:
- Vaginal Swab: Both conditions often require a swab of the vaginal area to collect a sample for further analysis.
- Visual Inspection: Providers will look for physical signs like the type and consistency of the discharge, swelling, and redness.
