What Could Cause My Vaginal Discharge to Smell Like Vinegar?

Your vagina has its own natural acid called lactic acid that helps keep it clean and healthy. Sometimes, this can give your discharge a mild vinegar-like odor, and that is normal for many people. However, if you notice that the vinegar smell is strong or has suddenly changed, it could mean that the balance of bacteria in your vagina is a bit off. One common cause of this imbalance is bacterial vaginosis, where the healthy bacteria (called lactobacilli) decrease and other bacteria proliferate, releasing chemicals that might smell like vinegar. Other factors, like using certain soaps, hygiene products, or even changes in your diet, can also affect the natural acidity and odor. If you do not have any other symptoms like itching, burning, or irritation, the odor by itself may not be a concern. But if you notice additional changes or discomfort, it is a good idea to check in with a healthcare provider. They can run tests and help figure out if any treatment is needed to restore a healthy balance.
