Why does my vaginal discharge smell like urine?

Your body naturally produces vaginal discharge to help clean and protect your vagina. Sometimes, this discharge might have a smell that reminds you of urine.

One common reason is that urine can mix with the vaginal secretions, e.g. from some residual urine after urination. This can happen during wiping or even during everyday movements.

Another possibility is that an imbalance in the natural bacteria, such as in bacterial vaginosis, is changing the chemicals in your vaginal discharge. In this condition, the healthy bacteria (lactobacilli) decrease and other bacteria take over, which can create chemical substances that give off an odor similar to urine.

While a slight urine-like smell can sometimes be normal, especially if it's related to a little urine contamination, any strong, unusual smell that persists or comes with other symptoms like irritation, itching, or burning should be evaluated. You can start by using a free symptom checker to better understand your symptoms, and then follow up with a healthcare provider if needed to maintain good vaginal health.
