Chlamydia: Testing and Treatment in English near Seongsu Station

 Quick answer: Chlamydia is one of the most common bacterial sexually transmitted infections. Most women have no symptoms, but untreated infection can lead to pelvic inflammatory disease and fertility problems. It is diagnosed with a swab or urine PCR test and cured with antibiotics. At Eunice Women's Clinic near Seongsu Station, a female OB-GYN offers confidential testing and treatment in English.

What is chlamydia?

Chlamydia is a sexually transmitted infection (STI) caused by the bacterium Chlamydia trachomatis. It is passed on through vaginal, anal, or oral sex, and it can infect the cervix, urethra, rectum, and throat. It is most common in people under 25 and in people with new or multiple partners, but anyone who is sexually active can get it.

What are the symptoms of chlamydia?

Most women with chlamydia have no symptoms, which is why regular testing is important. When symptoms occur, they may include:

  • Increased or changed vaginal discharge
  • Bleeding after sex or between periods
  • Burning when urinating
  • Pain during sex
  • Lower abdominal or pelvic pain

What causes chlamydia and who is at risk?

Chlamydia spreads through sexual contact with someone who has the infection, even if they have no symptoms. Risk is higher with a new partner, more than one partner, a partner who has other partners, not using condoms, or a past STI. It is not spread by toilet seats, swimming pools, or sharing towels.

When should I see a doctor?

Get tested if you have symptoms, if a partner has been diagnosed with an STI, after sex without a condom with a new partner, or before stopping condoms in a new relationship. Many guidelines recommend yearly chlamydia testing for sexually active women under 25 and for older women with risk factors. Testing is also important before an IUD insertion or in pregnancy. Seek prompt care if you have fever or pelvic pain.

Why is treatment important?

Untreated chlamydia can move up into the uterus and fallopian tubes and cause pelvic inflammatory disease(PID). PID can lead to long-term pelvic pain, ectopic pregnancy, and difficulty getting pregnant. In pregnancy, chlamydia can be passed to the baby during birth. Early testing and treatment greatly lower these risks.

How is chlamydia diagnosed at the clinic?

Chlamydia is diagnosed with a nucleic acid amplification test (NAAT), commonly called a PCR test, which is highly accurate. The sample can be a swab from the cervix or vagina, taken during a short exam, or in some cases a urine sample. In Korea, STI PCR panels often test for several organisms at once, such as chlamydia, gonorrhea, trichomonas, and mycoplasma and ureaplasma. The doctor may also recommend blood tests for HIV and syphilis. See STD testing for details.

How is chlamydia treated?

Chlamydia is treated with prescription antibiotic tablets. Important points:

  • Take all of the medicine exactly as prescribed.
  • Avoid sex until you and your partners have completed treatment and the waiting period the doctor advises (commonly about 7 days).
  • Recent sexual partners should be tested and treated, even without symptoms.
  • A repeat test about three months after treatment is recommended, because reinfection is common.
  • In pregnancy, a test of cure is also recommended; the doctor will choose a medicine that is safe in pregnancy.

Individual results vary.

How can I prevent chlamydia?

  • Use condoms or dental dams correctly every time.
  • Get tested with each new partner, and ask partners to test too.
  • Have regular STI checks if you are under 25 or have new or multiple partners.

Frequently asked questions

How long after sex can chlamydia be detected?

PCR tests can usually detect chlamydia about one to two weeks after exposure. If you test earlier than this, the doctor may suggest repeating the test later to be sure.

Can chlamydia go away on its own?

Chlamydia can sometimes clear without treatment, but it often lasts for months and can cause damage without symptoms. Because it is easily treated with antibiotics, testing and treatment are strongly recommended.

Can I have chlamydia and not know it?

Yes. Most women with chlamydia have no symptoms. This is why testing is recommended after new partners and for sexually active women under 25, even when you feel well.

Does chlamydia affect fertility?

Untreated chlamydia can cause pelvic inflammatory disease, which can scar the fallopian tubes and make pregnancy harder. Prompt treatment lowers this risk. If you had chlamydia in the past, you can mention it at a fertility consultation.

Can I get chlamydia again after treatment?

Yes. Treatment does not give immunity. Reinfection is common, especially if a partner was not treated, so a repeat test is recommended about three months later.

Is the test covered by insurance in Korea?

When testing is medically indicated, some STI tests may be covered by Korea's National Health Insurance, while screening without symptoms may not be. Coverage rules can change, so ask the clinic when you book.
