Chlamydia: Symptoms & Signs

Medically Reviewed on 9/10/2019

Chlamydia is a common sexually transmitted disease (STD). It affects both men and women and, in most cases, does not cause any symptoms. When it does produce symptoms and signs, these may not appear for weeks after your infection. Symptoms in women include burning with urination and an abnormal vaginal discharge. Abdominal or pelvic pain is sometimes present. Blood in the urine, urinary urgency (feeling an urgent need to urinate), and increased urinary frequency can occur if the urethra is infected. In men, symptoms, when they occur, can include a discharge from the penis and a burning sensation when urinating. Pain in the testicles sometimes occurs. In both men and women, infection of the rectum can cause rectal pain, bleeding, and discharge from the rectum.

Causes of chlamydia

Chlamydia is caused by an infection with Chlamydia trachomatis bacteria. The bacteria can be present in the cervix, urethra, vagina, and/or rectum of an infected person. The bacteria can also live in the throat. Any kind of sexual contact (vaginal, anal, or oral) can spread the infection.
