The most common causes of unpleasant vaginal odor are: Bacterial vaginosis (BV): An infection that's caused by an imbalance in your vagina's flora. BV is responsible for the fishy smell most commonly associated with unpleasant vaginal odors. The fishy smell may be especially strong after sex.
Temporary vaginal odor is common and often goes away on its own. Vaginal odor is considered normal if you don't have other symptoms. But if the odor is persistent and you're experiencing burning, itching, discharge, or irritation, it's a good idea to see your doctor for a vaginal exam.
Bacterial vaginosis is an overgrowth of bacteria typically present in the vagina. It's a common vaginal condition that can cause vaginal odor. Trichomoniasis, a sexually transmitted infection, also can lead to vaginal odor. A yeast infection usually doesn't cause vaginal odor.
However, when the vagina has a strong, unpleasant smell that continues for days, it may be a sign of a health problem. Common causes of abnormal vaginal odors include: Bacterial vaginosis, an infection caused by bacterial overgrowth. Trichomoniasis, a sexually transmitted infection caused by a parasite.
Many women become concerned that other people can detect the odor around their vulva and vagina. In reality, women are most sensitive to their own odor, and it's very unlikely that others who don't have intimate contact with them can smell it.
Trimethylaminuria (TMAU) is an uncommon condition that causes an unpleasant, fishy smell. It's also called "fish odour syndrome". Sometimes it's caused by faulty genes that a person inherits from their parents, but this isn't always the case. There's currently no cure, but there are things that can help.
Try bathing or showering every day with a mild soap and warm water, and wear cotton underwear. If your discharge continues to have an odor, you may have bacterial vaginosis (BV). BV is a vaginal infection but it's not considered to be a sexually transmitted infection (STI).
So, how often do you need to do it? Stick to cleaning once a day. If you wash any less, you might not be getting rid of the buildup of sweat and secretions; if you do it any more than once a day, you could be disrupting the delicate balance of your vaginal area.
In fact, the best way to stay clean is to take daily showers or baths using warm water and soap, making sure to wash in between the folds or creases of your skin and pubic hair, and completely drying the area before putting on clean, breathable underwear.
BV is a result of an imbalance of “good” and “harmful” bacteria in a vagina. Douching, not using condoms, and having new or multiple sex partners can upset the normal balance of vaginal bacteria, increasing your risk for getting BV.
Symptoms of bacterial vaginosis
This discharge will usually be white or grey, thin or watery and have a strong, unpleasant fishy smell. This can be more noticeable during and after sex, and during periods.
Groin sweat contains fatty acids and proteins which feed bacteria. As the bacteria break down the nutrients in groin sweat, foul-smelling acids are left behind.
The vagina usually has only a mild odor or sometimes no odor at all. A "fishy" smell or other strong vaginal odor might mean there's a problem. Conditions that cause a strong vaginal odor might also cause other vaginal symptoms such as itching, burning, irritation or discharge.
Excess vaginal discharge can occur due to arousal, ovulation, or infections. Normal vaginal discharge contains a mixture of cervical mucus, vaginal fluid, dead cells, and bacteria. Females may experience heavy vaginal discharge from arousal or during ovulation.
Clear and stretchy — This is “fertile” mucous and means you're ovulating. Clear and watery — This occurs at different times of your cycle and can be particularly heavy after exercising. Yellow or green — May indicate an infection, especially if it's thick or clumpy like cottage cheese or has a foul odor.
Infections might be the cause. You may have bacterial vaginosis, a yeast infection, or an STI. Menopause-related hormonal changes, diabetes, or skin conditions are other possible causes. Or irritation from and allergic reactions to detergents and other products could be at work.
