Urethral discharge is any substance that is released from the urethra, the tube that carries urine from the bladder to the outside of the body. It may be a sign of infection, and should be checked by a healthcare provider. The most common type of urethral discharge is mucus, which is produced by glands in the urethra. This may be a normal part of the body's natural defense against infection. Urethral discharge may also be a sign of a sexually transmitted infection, such as gonorrhea or chlamydia. It can also be caused by irritation from soaps, spermicides, or chemicals in the urine. Urethral discharge can range from clear and watery to cloudy and thick. It may also have a strong odor, or it may have no smell at all. It may be accompanied by other symptoms, such as pain or burning while urinating, or increased frequency of urination. If you have any of these symptoms, it is important to see a doctor right away. A doctor will be able to diagnose the cause of the urethral discharge and provide treatment. Treatment may include antibiotics, antiviral medications, or topical creams. It is important to follow all instructions given by the doctor to ensure that the infection is cleared up completely.
