What is Chlamydia?

Chlamydia is one of the most common sexually transmitted infections (STI's) in the UK. Chlamydia is most commonly seen in people under the age of 25 and in people who do not use condoms.

How do I know I’ve got it?

70% women have no symptoms (7 of 10 women) 50% men have no symptoms
The simple answer is to get tested.

Some symptoms that may suggest you have Chlamydia are:


  • Pain passing urine
  • Change in your discharge
  • Bleeding between periods
  • Bleeding after sex
  • Pain during sex


  • Pain passing urine
  • Discharge from your penis
  • Pain in your testicles
  • Rectal pain and discharge

How do you get it?

  • Through unprotected sexual intercourse (having sex with no condom)
  • Sharing sex toys
  • It can also be spread by your fingers from your genitals to your eyes
  • An infected mother can pass it to her baby’s eyes and lungs at birth

Where can I get tested?

  • Your GP
  • Sexual Health Clinics

What is the treatment?

  • Antibiotics will get rid of the infection.
  • Avoid having sex until 1 week after you and your partner(s) have been treated.
  • It is recommended that you get a test at 3-12 months after you had the infection to ensure you have not been re-infected.

Sexual partners

It is essential that your sexual partner(s) are treated. You can discuss this with the health adviser who can help you tell/talk to your partner to get tested and treated.

What if I don’t get treated?

Chlamydia could lead to other more serious problems such as pelvic inflammatory disease (PID) when the infection gets into the womb and fallopian tubes. This could lead to problems such as infertility and ectopic pregnancy. This is uncommon.
In men infection can spread to the testicles this is uncommon.
If your infection is untreated you may pass it onto other sexual partners.
How do I make sure I don’t get Chlamydia again?
The best way to prevent all sexually transmitted infections is to practice safer sex. This means using a condom for vaginal, oral or anal sex.
