Why do I pee so much at night? (men)

Last updated September 3, 2026.

First suspect over 50: the prostate - BPH, the most common prostate problem in men over 50 per NIDDK, squeezes the urethra and blocks full emptying, producing the classic cluster: night trips, weak stream, hesitancy, dribbling. Benign, very treatable - evening fluid and caffeine cuts first, then medications and procedures. But not always the prostate: diabetes, sleep apnea (the heart releases a diuretic hormone when breathing stops at night), and heart and kidney issues do it too - which is why the check matters. Urgent: blood, pain, fever, or a stream that stops.
