How do I find out if I have chlamydia?

You need to be examined by a doctor. Chlamydia can be diagnosed by a swab taken from place which may be infected, or by a urine sample. Your sexual partner must also be tested for the disease.

What is the treatment?

Chlamydia can be effectively treated with antibiotics. It is important to take all the prescribed tablets; otherwise infection may not be properly cured. Sexual partners who could have been infected should be treated at the same time. If not, you may be infected again.

Sexual intercourse should be avoided until you and your partner(s) have finished all the medication and been treated.

To ensure the infection has been cured, you have to return to your doctor or clinic for a follow-up.

How can I help myself?

Chlamydia can be a serious disease that can affect your fertility. It must be thoroughly treated. Do not treat yourself; it may harm you and your sexual partner.

If you have any suspicions, you should seek medical advice.

Health Alert

In men, complications caused by chlamydia are uncommon. But if untreated, it may lead to painful inflammation of the testicles, which can cause infertility.
