Many women experience a noticeable odor from their intimate area at some point, and while it can be unsettling, it’s not always a cause for concern. That distinct fishy smell that sometimes shows up may occur for no specific reason at all.
In many cases, simply showering and changing into clean underwear is enough to restore your body’s natural scent.
However, if the odor lingers despite regular hygiene or appears alongside other unusual symptoms, it might be a good idea to schedule a visit with your gynecologist. If the fishy smell comes with itching, discomfort, or other unexpected changes, it could indicate an underlying condition—bacterial vaginosis being one of the most common.
Bacterial vaginosis happens when there’s a disruption in the natural balance of bacteria in the vagina. Common signs include a thin, gray or white discharge, a strong fishy smell (often more noticeable after sex), and irritation or burning. It requires treatment with prescribed antibiotics.
Other possible causes of a fishy vaginal odor include poor hygiene, tight or non-breathable clothing, and trapped sweat—all of which can contribute to unpleasant smells.
Trichomoniasis, a sexually transmitted infection (STI) caused by a parasite, is another potential cause. Unlike home remedies, this condition must be treated with medication prescribed by a healthcare professional.
A surprisingly common issue is leaving a tampon in for too long. This can result in a strong, rotten smell that some people confuse with a fishy odor.
While in many cases the odor goes away naturally, if it persists longer than expected, it’s important to get checked for bacterial infections or other possible causes.
To help prevent these kinds of odors from developing, it’s best to practice good hygiene. Gently cleanse the external genital area with warm water and mild, unscented soap (avoid douching), wear breathable cotton underwear, use protection during sexual activity, and steer clear of scented feminine products.
Probiotics may also help support a healthy vaginal environment—just be sure to check with your doctor before adding them to your routine.
