Complications from untreated infectious cervicitis depend on the pathogen. Untreated microbial cervicitis can spread throughout the genital tract, infecting the lining of the uterus (endometritis) and the Fallopian tubes (salpingitis). Such generalized infections can result chronic pelvic pain, or infertility. Spread to the pelvic organs can cause pelvic inflammatory disease (PID) resulting in adhesion formation and tubal blockage. If cervicitis due to an STI is present during pregnancy, the infant may be infected at the time of delivery, resulting in a newborn eye infection that can eventually lead to blindness. Although less common, the infant may develop pneumonia caused by a chlamydial infection present in the cervix at the time of delivery
