Chlamydia is a sexually transmitted infection (STI) caused by the bacterium Chlamydia trachomatis. Many people who have chlamydia may not experience any symptoms, so the only way to confirm if you have chlamydia is through testing.
If symptoms do occur, they can vary depending on the affected area of the body, but may include:
- Pain or discomfort during sex or urination
- Discharge from the penis, vagina or rectum
- Pain or discharge from the eyes (if the infection has spread to the eyes)
- Abnormal vaginal bleeding (between periods or after sex)
It is important to get tested for chlamydia if you are sexually active, especially if you have multiple partners or engage in unprotected sex. Testing usually involves a urine sample or swab from the affected area. Treatment for chlamydia typically involves antibiotics, and it is important to complete the full course of treatment even if symptoms disappear. Untreated chlamydia can lead to serious health problems such as pelvic inflammatory disease and infertility.
