Did You Know? Vaginal discharge is a substance composed of a mixture of liquid, cells and bacteria to serve to protect and lubricate the vagina. It is produced constantly by the cells of the vagina and cervix and exits the body through the vaginal opening. Any change in the balance of normal bacteria in the vagina can affect the smell, colour, or texture of the discharge. A few of the things that can upset that balance include: antibiotic use, sexually transmitted infections, diabetes and cervical cancer. Find out more in our blog post.
