What causes chlamydia?

  • Chlamydia is an infection that is spread through sexual contact.
  • If a person is infected, they can pass it on to their sexual partner/s easily through; Vaginal, anal and oral sex (higher risk), Sharing sex toys, Mutual masturbation, Fingering (lower risk)
  • Chlamydia can still be passed on even when the infected partner hasn’t ejaculated.

Symptoms

In adults
  • Often people will have chlamydia without any obvious symptoms, so can pass it on to their sexual partner without realising.
  • If they do, they may experience; Abnormal vaginal discharge – it may be discoloured and have a different smell or a different texture than usual, Vaginal bleeding –which may occur more after sex, White coloured discharge from the penis or rectum, Pain at the penis opening – it may be red or darker in colour, Painful and/or swollen testicles, Pain in the lower abdomen, Pain when peeing
  • People can also get the chlamydial infection in their throat, but it’s quite rare and often doesn’t present with any symptoms.
In babies
  • Sometimes, a baby can catch chlamydia from their mother during birth. This can result in ear and eye infections or pneumonia which is treatable with antibiotics.

Treatments

For adults
  • Chlamydia is easily treated with antibiotics tablets.
  • As with any antibiotics, it’s very important to take the full course, even if you start to feel better partway through.
  • Some antibiotics can reduce the effectiveness of the contraceptive pill, so an alternative contraceptive method such as condoms may need to be used. Discuss this with your doctor.
  • During treatment, a person can still be infectious. So they should either refrain from sexual activity or use a condom for 1 week from the start of their treatment.
  • A follow-up test is recommended 3 months after treatment to make sure the patient hasn’t been re-infected.
  • All sexual contacts in the last 3 months should be notified that they may have been exposed to Chlamydia and be advised to get tested.
Medications
  • Chlamydia can be treated with a 7-day course of doxycycline, or a one-off dose of azithromycin – these are both types of antibiotics.
Proactive protection
  • Condoms are one of the best protection against sexually transmitted infections (STIs) like chlamydia. You can use them during vaginal, anal or oral sex to create a barrier.
  • A dam is another type of barrier protection that can be used to cover the female genitals during oral sex, or when rubbing genitals together. It’s essentially a light sheet of latex or soft plastic.
  • It’s best to avoid sharing sex toys, but if you’re going to, be sure to clean them between each new person.

Should I see a doctor?

  • If you have any symptoms, see a doctor, nurse or sexual health clinic to get tested.
  • Because chlamydia may not have symptoms, you should get regular STI checks at least once a year if you are sexually active This is particularly true if; You have a new sexual partner, You’ve had sexual contact with someone that has had other sexual partners recently
  • Those having sex with multiple partners should have more regular STI tests (every 3 months).
Which specialist should I visit?
