About This Disease

Chlamydia is a common sexually transmitted infection (STI) caused by the bacterium Chlamydia trachomatis. It's one of the most frequently reported bacterial STIs worldwide. Many people with chlamydia experience no symptoms, which makes regular screening important for sexually active individuals.

Possible Causes

  • Unprotected vaginal, anal, or oral sex with an infected partner
  • Mother-to-child transmission during childbirth
  • Sharing sex toys that haven't been washed or covered with a new condom

Symptoms

Many people with chlamydia experience no symptoms. When symptoms do occur, they may include:

In Women:

  • Abnormal vaginal discharge
  • Burning sensation when urinating
  • Pain during intercourse
  • Lower abdominal pain
  • Bleeding between periods

In Men:

  • Discharge from the penis
  • Burning sensation when urinating
  • Pain and swelling in one or both testicles
  • Rectal pain, discharge, or bleeding (if infected through anal sex)

Prevention

Medical Prevention

  • Consistent and correct use of condoms
  • Regular STI testing for sexually active individuals
  • Mutual monogamy with an uninfected partner
  • Pre-exposure prophylaxis (PrEP) for high-risk individuals

Natural Prevention

  • Limiting number of sexual partners
  • Open communication with partners about STI status
  • Maintaining a healthy immune system
  • Proper hygiene before and after sexual activity

Treatment Options

Chlamydia is curable with proper antibiotic treatment. It's important to complete the full course of antibiotics even if symptoms disappear.

Medical Treatment

  • Azithromycin (single dose)
  • Doxycycline (twice daily for 7 days)
  • Alternative antibiotics for pregnant women
  • Follow-up testing 3 months after treatment

Supportive Care

  • Abstaining from sex until treatment is complete
  • Notifying all recent sexual partners
  • Drinking plenty of fluids
  • Probiotics to restore healthy bacteria

Potential Complications

If left untreated, chlamydia can lead to:

  • Pelvic inflammatory disease (PID) in women
  • Ectopic pregnancy
  • Chronic pelvic pain
  • Infertility in both men and women
  • Increased risk of HIV transmission
  • Reactive arthritis
