Chlamydia often causes no symptoms- that means you can be infected but not show any obvious signs.

If symptoms occur in women, they may include:

• Vaginal discharge
• Pain or burning when passing urine
• Vaginal bleeding or spotting between periods. In particular, bleeding after sex
• Pain or discomfort in the lower abdomen, which can be made worse by having sex
• Anorectal symptoms (pain or discharge around the anus) 

If symptoms occur in men, they may include:

• Pain or burning when passing urine
• Discharge from the end of the penis
• Pain or discomfort at the end of the penis
• Anorectal symptoms (pain or discharge around the anus)

Complications of Chlamydia can include:

• Infertility
• Epididymo-orchitis (inflammation of the testes and epididymis)
• Cervicitis (inflammation of the cervix)
• Pelvic Inflammatory Disease (PID)
• Pregnancy-related complications, including Ectopic pregnancy, Premature rupture of the membranes, preterm delivery, and low-birthweight infants.
• Reactive arthritis: arthritis, sometimes with rash and gastrointestinal (gut-related) symptoms
• Conjunctivitis (inflammation of the eye(s) )
• Perihepatitis (inflammation around the liver)

If you think that you have been infected with Chlamydia, it is essential that you get treatment,  even if you have no symptoms. Serious complications may develop if it is left untreated, and you may pass it on to your sexual partner(s).

If you are sexually active it’s important to get checked for Chlamydia regularly, particularly if you have multiple partners.
