Grey vaginal discharge can be a sign that the normal balance of bacteria in your vagina has changed, often due to an infection like bacterial vaginosis.
Normally, the vagina makes clear or white discharge to keep itself clean. When the discharge turns grey, it can mean that the mix of tiny germs in your body has changed. This change is sometimes seen in bacterial vaginosis, a common infection where the good bacteria, called lactobacilli, drop in number and other bacteria take over. This imbalance makes the discharge look grey and may come with a mild smell or irritation. In some cases, grey discharge might also be linked to other infections or inflammation that affect the vaginal area. It is important to keep track of any other symptoms you might have, like itching, burning, or changes in odor. If you notice these changes, it is a good idea to talk to a healthcare provider. They can order simple tests to find out exactly what is happening and decide on the best treatment. Keeping an eye on your body's changes helps you stay healthy and comfortable.
