White discharge from the urethra often indicates pus, which is a common sign of an infection such as urethritis. Urethritis is inflammation of the urethra, typically caused by bacterial infections including sexually transmitted infections (STIs) like chlamydia or gonorrhea, though non-infectious causes are also possible.
Because urethral discharge can point to several different conditions—some of which require prompt treatment to prevent complications—it's important to identify the underlying cause quickly. Taking a free, instant, online symptom check can help you better understand your symptoms, narrow down potential causes, and guide you toward the right next steps for care.
