Chlamydia is a sexually transmitted infection caused by the bacterium chlamydia trachomatis. It is the most common sexually transmitted infection in the UK, often causes no symptoms, and can be passed on to others without you realising. This can be by vaginal, anal or oral sex. However, symptoms and complications may develop if it is left untreated, sometimes months or even years afterwards. These include persistent pelvic pain and infertility.


If you are at risk of picking up any sexually transmitted infections, then it is highly advisable to be tested and treated without delay. Early treatment reduces the risk of complications in the future.

If the test is positive, then you may need further testing to see if you have picked up any other infections. At JA Medical, our doctor or nurse will provide you with impartial and confidential advice based on your sexual history and symptoms, and recommend the most appropriate screening / testing.


Wearing a condom during sex helps to prevent chlamydia and other sexually transmitted infections. The risk of infection increases with the number of changes of sexual partner.


Treatment for chlamydia involves using antibiotics.
