Why bacteria levels change is not known, but the normal lactobacilli can be replaced by other, infection-causing bacteria.
Gardnerella is the bacteria most often associated with bacterial vaginosis. It is the lack of lactobacilli and overgrowth of these other bacteria that cause the symptoms of infection.
With bacterial vaginosis, a woman may see a thick or whitish discharge or one that is slippery and clear. It is not likely to itch or burn. A fishy odour may be noticeable, especially during intercourse.”
What is abnormal vaginal odour?
All vaginas naturally produce scents. The smells that your vagina emits communicate information about your lifestyle, activities and overall health. For instance, vaginal odour often varies throughout your menstrual cycle. Vaginal discharge often smells most pronounced midcycle. Your vagina may give off a stronger odour after intercourse or a workout.
Many vaginal odors signal short-term shifts in your pH level and aren’t cause for concern. For example:
- A vaginal odor that smells slightly sour or tangy may be a sign that the pH level in your vaginal flora is slightly more acidic than is typical. This smell is associated with the good bacteria in your vagina, lactobacilli. Some people describe the odor as yeasty, similar to sourdough bread.
- A slightly sweet or bittersweet smell, like molasses or gingerbread, may also be a sign that your pH levels have changed.
- Your vaginal discharge may smell slightly metallic — like copper pennies — when you’re menstruating. This is because period blood contains iron.
- A vagina that smells like ammonia may be a sign that there’s urine residue on your genitals (vulva) or that you’re dehydrated.
- A skunk-like scent or a smell similar to body odour may be a sign that you’re stressed and your sweat glands are working overtime.
Temporary vaginal odour is common and often resolves on its own. Odours may be related to hormonal changes or even diet. For example, foods with a strong odour, like garlic or fish, can cause odour changes in your vagina.
However, an unpleasant odour that doesn’t go away may be a sign of an underlying condition that requires medical attention.
