Yellow vaginal discharge can be a sign that there is an infection or a change in the natural balance of bacteria in your vagina.
Your body naturally produces discharge to help keep your vagina clean. Normally, it is clear or white, but when it turns yellow, it may mean that your body is fighting off an infection. One common reason for yellow discharge is when germs, like those that cause trichomoniasis or bacterial vaginosis, overpower the good germs and upset the normal balance. This overgrowth can change the color of your discharge to yellow. Sometimes, inflammation or irritation in the vaginal area can also cause it to have a yellow tint. The yellow color means that the healthy bacteria that normally keep the vagina safe have been disturbed, allowing other germs to grow. If you notice a yellow color, especially if it comes with itching, burning, or a strong smell, it is important to see a healthcare provider. They can help determine if an infection is present and decide what treatment you might need. Paying attention to any changes in your discharge helps you make sure your body stays healthy.
