Why Am I Peeing So Often at Night? Common Causes Explained

Frequent nighttime urination isn't just frustrating; it could also be a sign of an underlying health issue, including prostate problems.

What Is Nocturia?

Nocturia is the medical term for waking during the night one or more times to urinate. While it’s normal to get up once occasionally, getting up two or more times every night may indicate a problem with your bladder, prostate, or overall health.

Common Causes of Frequent Nighttime Urination

1. Enlarged Prostate (BPH)

The most common cause of nocturia in men over 50 is benign prostatic hyperplasia (BPH)—an age-related enlargement of the prostate gland. As the prostate grows, it presses against the urethra and bladder, causing:

Frequent urination
Weak or slow stream
Incomplete bladder emptying
Sudden urges to go—especially at night
