Chlamydia

Professionally updated: February 24, 2024

Chlamydia is a sexually transmitted infection (STI) caused by the bacterium Chlamydia trachomatis. It is a common infection that often shows no symptoms, meaning many people are unaware that they are infected. Fortunately, Chlamydia is easy to diagnose and treat with antibiotics.

Symptoms of chlamydia

It is essential to understand that chlamydia often progresses without visible symptoms. This can contribute to the unknowing spread of the infection, which emphasizes the importance of regular health checks and testing.

Symptoms in women

Women with chlamydia often experience mild or no symptoms. However, when symptoms are present, they can include:

  • Pain when urinating: A burning or stinging sensation.
  • Abdominal pain: The pain can be constant or only occur during sex.
  • Abnormal vaginal discharge: Changes in color, odor, or consistency of the discharge.
  • Irregular periods or bleeding between periods.

If the infection spreads, women may also experience fever and lower back pain.

Symptoms in men

Men can also have chlamydia without showing symptoms. But symptoms can include:

  • Penile discharge: Often clear, white or yellow discharge.
  • Pain when urinating: A burning or stinging sensation.
  • Testicular pain and swelling: Especially in one testicle.

Asymptomatic course

As chlamydia can often progress without clear symptoms (asymptomatic), regular screening is essential, especially for those with multiple sexual partners or those who don't use protection during intercourse. Asymptomatic chlamydia can still lead to serious health complications, such as infertility, if left untreated.

If you recognize any of these symptoms or want to get tested as a preventative measure, it's important to contact a healthcare provider or book an appointment for a chlamydia test. Our experienced doctors are ready to advise and guide you through the process, from testing to treatment and prevention.

Diagnosis of chlamydia

Getting an accurate diagnosis is essential for successful treatment and preventing the further spread of chlamydia. Below you'll find details on how chlamydia is diagnosed and why it's important to get tested regularly.

Diagnostic methods

There are two main methods for diagnosing chlamydia:

Urine test

This method requires a simple urine sample. The patient should provide a sample of their first morning urine, as this has the highest concentration of bacteria.

Cotton swab

Here, samples are taken from the areas that could potentially be infected. For women, this often involves a sample from the cervix, while men will have a sample taken from the urethra. If you have had anal sex, the doctor may also take a sample from the rectum.
The test is quick and painless, and you will often get the results within a few days.

The importance of regular testing

Although chlamydia can be effectively treated with antibiotics, prevention and early detection are key to avoiding long-term health complications. This is especially true if:

  • You have a new sexual partner.
  • You have had unprotected sex with a partner whose sexual health you don't know.
  • You or your partner have had sex with other partners without protection.
  • You are showing symptoms that could be related to chlamydia.

Regular screening is a responsible practice that protects both your own health and the health of your sexual partners. If you're sexually active, it's recommended that you get tested for chlamydia and other sexually transmitted infections regularly, especially if you don't use condoms consistently or have multiple partners.

Chlamydia treatment

Being diagnosed with chlamydia can be worrying, but it's important to know that with timely and proper treatment, the infection can be completely cured with no long-term effects. Below you will find a step-by-step guide to treatment and important considerations during the process.

Step-by-step guide to treatment

Diagnosis confirmed

Once your chlamydia diagnosis is confirmed, your doctor will prescribe appropriate antibiotics to treat the infection.

Receiving antibiotics

You will typically receive a single dose of antibiotics, often as tablets. Follow your doctor's instructions carefully regarding dosage and use.

Period without sexual activity:

It is crucial that you abstain from sex, including vaginal, anal and oral sex, until the infection is cured, which typically takes about a week after starting treatment.

Follow-up testing

Your doctor may recommend a follow-up test to make sure the infection is completely cleared.

Inform Sexual Partners

It is of the utmost importance that all your current and previous sexual partners (within the last two months) are informed about your diagnosis so that they can also be tested and treated if necessary. This will help prevent further spread of the infection and possible complications with them.

Considerations and precautions during treatment

  • Follow your doctor's instructions carefully and take the full prescribed amount of antibiotics, even if you feel better sooner.
  • Avoid alcohol during treatment as it can interact with the medication and reduce its effectiveness.
  • Do not resume sexual activity until both you and your partner are fully treated and the infection is cured.

If you have any questions or concerns during your treatment, it's important to consult your doctor, who will be able to guide you through the process and provide advice and support. Being open and honest with healthcare professionals is essential to ensure you receive the best possible care and advice during your treatment.

Prevention of Chlamydia

Safe Sex

Practicing safe sex is the most effective method of preventing chlamydia:

  • Use of condoms and dental dams: Condoms, both male and female, and dental dams should be used consistently and correctly during all forms of sexual activity (vaginal, anal and oral sex) to reduce the risk of transmission.
  • Lubrication: Use water-based or silicone-based lubricant during sex to avoid breakage or damage to the condom.

Regular STI Testing

  • Frequent check-ups and tests: Get regular check-ups and tests for Chlamydia and other STIs, especially if you have multiple sexual partners or are in a new sexual relationship.
  • Follow-up after unprotected sex: If you have had unprotected sex, it is important to follow up quickly by getting an STI test.

Open and Honest Communication

  • Dialogue with partners: By talking openly with your sexual partners about sexual health, testing and STI status, you can make informed decisions about protection and prevention together.
  • Inform partners of a positive test: If you test positive for chlamydia or another STI, inform your current and former partners so they can get tested and treated if necessary.

Vaccination and Education

While there is no vaccine for chlamydia, it is important to consider vaccination against the STIs for which there are vaccines, such as HPV and hepatitis B. Furthermore, education and awareness about sexual health and STIs is essential for effective prevention.

By taking these steps, you can actively contribute to your own sexual health and well-being, as well as protect your current and future partners from the risk of chlamydia and other sexually transmitted infections.

    Frequently asked questions about ECG

    Can I get chlamydia without having sexual intercourse?

    Chlamydia is primarily spread through sexual contact, which includes vaginal, anal and oral sex. It is unlikely to be contracted through other means as the bacteria does not survive long outside the human body.

    How do I know if I have chlamydia if I don't always have symptoms?

    Since chlamydia often progresses without symptoms (asymptomatic), regular testing is essential, especially if you have multiple sexual partners or practice unprotected sex. If you experience symptoms such as abnormal discharge, pain during urination or intercourse, you should seek medical attention and get tested as soon as possible.

    Can chlamydia be treated and cured?

    Yes, chlamydia can be effectively treated and cured with antibiotics. However, it is important to take the full prescribed dose of medication, even if symptoms disappear before the course of medication is completed. Both partners should be treated at the same time to prevent reciprocal infection.

    Can I get chlamydia more than once?

    Yes, previous infection with chlamydia does not confer immunity and you can therefore become infected again if you are exposed to the bacteria. This highlights the importance of continuing to practice safe sex even after successful treatment for chlamydia.
