    Chlamydia - What Happens

    Chlamydia does not cause long-term problems if it is treated before any complications develop. Left untreated, chlamydia can lead to many complications, especially for women. If a woman has chlamydia when she gives birth, her newborn can be infected.

    Having a chlamydia infection that was cured does not protect you from a future infection. A new exposure to chlamydia will reinfect you, even if you were treated and cured.

    Having chlamydia increases your risk of becoming infected with human immunodeficiency virus (HIV) if you are exposed to the virus.1

    Untreated chlamydia can cause a variety of complications.

    Complications in women

    Complications in pregnant women

    Complications in newborns

    Complications in men

    Other complications of untreated chlamydia in all people

    • Conjunctivitis, spread by touching the infected area and then touching the hand to the eye
    • Inflammation of the mucous membrane of the rectum (proctitis), if the chlamydia is from anal sex
    • Varied symptoms, such as joint and eye inflammation, caused by bacterial infection (Reiter's syndrome, or reactive arthritis)
    • Lymphogranuloma venereum, or LGV. This is caused by a type of chlamydia that is usually rare in the United States, but it is becoming more common in men who have sex with men. It causes open sores in the genital area, headache, fever, fatigue, and swelling of the lymph nodes in the groin. It also causes proctitis in people who get chlamydia through anal sex.
