Frequent urination in men
Urinary frequency can occur with prostate enlargement, but it is not proof of BPH and should not be used to self-diagnose.
How the prostate can be involved
NIDDK lists urinary frequency among possible BPH symptoms. As the prostate enlarges, it can narrow the urethra and make bladder emptying more difficult.
Why symptoms need context
Urinary symptoms can have multiple causes. Persistent, new, painful or worsening symptoms are a reason to speak with a healthcare professional rather than relying on a supplement label.
What to do next
Track how often you urinate, whether you have urgency or pain, and whether the stream is weak or interrupted. Bring those details to a clinician. For related reading, see nighttime urination and weak urine flow.
