Frequent nighttime urination, or nocturia, is one of the earliest signs of an enlarged prostate — a condition known as benign prostatic hyperplasia (BPH). It's common in men over 40 and, in most cases, treatable.

This page explains why it happens and what treatment options are available, including UroLift and Rezum, two minimally invasive procedures offered at Gangnam St. Mary's Urology Clinic in Seoul.

1. Why Nocturia Happens

An enlarged prostate can press against the urethra, preventing the bladder from fully emptying. This means the bladder fills again sooner — often noticed as needing to urinate multiple times at night.

Common accompanying symptoms include:

Not all nocturia is caused by BPH. Fluid intake, medications, and other bladder conditions can also be factors, which is why a proper evaluation matters.

2. From Medication to Procedure

BPH is usually treated with medication first. When symptoms no longer respond well, or side effects such as dizziness or reduced sexual function become difficult to manage, minimally invasive procedures are typically considered next.
