If left untreated, vaginitis can become a more severe problem depending on the type you may have.
Those with trichomoniasis or bacterial vaginosis are more likely to get an STI due to the inflammation the disorders cause. Vaginosis is also often associated as a cause of pelvic inflammatory disease (PID), a serious infection that can cause infertility and chronic pain. For those who are pregnant, both trich and vaginosis are associated with premature deliveries and low birth-weight infants.
