Understanding the difference between a yeast infection and bacterial vaginosis
Changes in the vaginal area can sometimes be noticeable or unfamiliar. This may include sensations such as itching, changes in discharge, or a different odor. Because some of these signs can appear in different situations, it can be unclear what the underlying cause might be.
Two commonly discussed conditions are yeast infections and bacterial vaginosis (BV). While they can share certain characteristics, they are caused by different processes in the vaginal environment.
Yeast infections
A yeast infection, also known as vulvovaginal candidiasis, occurs when there is an overgrowth of Candida, a type of fungus that is naturally present in the vaginal area.
In medical literature, factors such as antibiotic use, hormonal changes, stress, or changes in immune function are often mentioned in relation to yeast overgrowth.
Yeast infections are commonly described as being associated with:
-
noticeable itching or irritation
-
redness or swelling of the vaginal area
-
thicker, white vaginal discharge
Odor is typically described as absent or mild.
Bacterial vaginosis (BV)
Bacterial vaginosis is described as a change in the composition of bacteria in the vaginal environment. It is often associated with a decrease in Lactobacillus bacteria and an increase in other bacterial species, such as Gardnerella vaginalis.
In research and clinical descriptions, BV is often mentioned in connection with:
-
a thinner, grayish vaginal discharge
-
a distinct or stronger odor
Itching is usually described as less prominent than with yeast infections, though experiences can vary.
Key differences often described in literature
| Feature | Yeast infection | Bacterial vaginosis |
|---|---|---|
| Discharge | Thick, white | Thin, grayish |
| Odor | None or mild | More noticeable |
| Itching | Commonly reported | Less commonly reported |
| Cause | Overgrowth of yeast | Change in bacterial balance |
A note on individual experience
While medical literature describes general patterns, individual experiences can differ. If symptoms are persistent, unclear, or concerning, consulting a healthcare professional is recommended.
