Chlamydia is one of the most common sexually transmitted infections (STIs) worldwide, caused by the bacterium Chlamydia trachomatis. Despite being easily treatable, it often goes undiagnosed because it rarely shows symptoms in the early stages. Left untreated, Chlamydia infection can lead to serious reproductive and urinary health complications in both men and women. Understanding what Chlamydia is, how it spreads, and the available Chlamydia treatments can help prevent long-term health problems.

What Is Chlamydia?

Chlamydia is a bacterial infection transmitted primarily through sexual contact, vaginal, anal, or oral with an infected person. It affects both men and women and can infect various areas of the body, including the genitals, rectum, throat, and eyes.

In women, untreated Chlamydia can cause pelvic inflammatory disease (PID), leading to infertility or chronic pelvic pain. In men, it can cause inflammation in the testicles or prostate, potentially leading to reproductive issues.

Because Chlamydia is related to multiple reproductive health problems, early diagnosis and treatment are crucial to preventing complications.

Chlamydia Is Caused By – Understanding the Infection

Chlamydia is caused by the bacterium Chlamydia trachomatis, a microscopic organism that thrives inside human cells. It spreads through:

  • Unprotected Sexual Contact – Vaginal, anal, or oral sex with an infected partner.
  • Transmission During Childbirth – Infected mothers can pass the bacteria to their babies, causing eye infections or pneumonia in newborns.
  • Sharing of Contaminated Sex Toys – Bacteria can survive briefly on objects, leading to indirect transmission.

It’s important to note that Chlamydia disease does not spread through casual contact such as hugging, kissing, or sharing utensils.

Chlamydia Symptoms

Chlamydia is often referred to as a “silent infection” because most people show no noticeable symptoms, especially in the early stages. When symptoms do appear, they may vary between men and women.

Chlamydia Symptoms in Women

  • Abnormal vaginal discharge (yellowish or with a strong odour)
  • Pain or burning during urination
  • Pain during sexual intercourse
  • Lower abdominal or pelvic pain
  • Bleeding between periods or after sex

Chlamydia Symptoms in Men

  • White, cloudy, or watery discharge from the penis
  • Burning or pain during urination
  • Pain and swelling in one or both testicles (though less common)

Other Possible Symptoms

  • Rectal Chlamydia Infection: Discharge, pain, or bleeding from the rectum.
  • Throat Infection: Sore throat after oral sex with an infected partner.
  • Eye Infection: Redness, itching, and discharge when bacteria enter the eye.

If left untreated, Chlamydia infection can spread to other parts of the body, leading to more severe complications.

Complications of Untreated Chlamydia

Ignoring or delaying Chlamydia treatment can result in long-term health problems:

  • Pelvic Inflammatory Disease (PID) – In women, untreated infection can damage the uterus and fallopian tubes, causing infertility.
  • Epididymitis – In men, it can lead to painful swelling near the testicles.
  • Reactive Arthritis – A form of arthritis that affects the joints, eyes, and urethra.
  • Increased Risk of HIV Transmission – Chlamydia can make individuals more susceptible to contracting HIV.

At SPARSH Hospitals, our specialists emphasise regular screening and prompt treatment to prevent such complications.

Chlamydia Diagnosis

Diagnosing Chlamydia is simple, quick, and highly accurate. Common diagnostic methods include:

  • Urine Test: Detects the presence of the bacteria.
  • Swab Test: A sample is taken from the cervix (in women) or urethra (in men).
  • Rectal or Throat Swab: For those who have had anal or oral sex.

Results are usually available within a few days, enabling early initiation of Chlamydia medication.

Chlamydia Treatment

Fortunately, Chlamydia is curable with the right antibiotics prescribed by a healthcare professional. Early diagnosis ensures a faster recovery and reduces the risk of complications.

Common Chlamydia Medications

  • Azithromycin – Usually given as a single, large dose.
  • Doxycycline – Taken twice daily for 7 days.

Your doctor may also recommend abstaining from sexual activity during and after treatment until the infection clears completely. It’s important that sexual partners are also treated to prevent reinfection.

Follow-up testing after 3 months is often recommended to ensure that the infection has been fully cured.

Chlamydia Prevention

Prevention is the most effective way to reduce the spread of Chlamydia infection. Here are several key strategies:

Practice Safe Sex

Use condoms consistently and correctly during vaginal, anal, and oral sex. This significantly reduces the risk of infection.

Regular Screening

Individuals who are sexually active, especially those under 25 or with multiple partners, should get tested for Chlamydia regularly.

Avoid Sharing Sex Toys

If sharing, ensure that toys are washed thoroughly and covered with a new condom each time.

Limit Sexual Partners

Reducing the number of partners helps lower the chance of exposure to STIs.

Open Communication

Discuss STI testing and protection methods with partners before engaging in sexual activity.

Get Treated Promptly

If diagnosed, start treatment immediately and ensure all partners are informed and treated as well.

At SPARSH Hospitals, our urologists and gynaecologists provide confidential testing, compassionate counselling, and expert guidance for STI prevention and treatment.

Chlamydia and Other Related Conditions

Chlamydia infection can be associated with or mimic symptoms of other reproductive health conditions:

  • Bartholin’s Gland Cyst: A blockage of the glands near the vaginal opening, sometimes triggered by infections like Chlamydia.
  • Vaginismus: Involuntary tightening of vaginal muscles often caused by pain or trauma linked to infections.

If you experience discomfort or unusual symptoms, consult a specialist at SPARSH to rule out such conditions.
