What prostate condition might cause excessive urinary frequency in older men?

Benign prostatic hyperplasia (BPH) is a common condition in older men characterized by the enlargement of the prostate gland. This enlargement can lead to urinary symptoms due to the pressure it exerts on the urethra, which narrows the passage and makes it difficult for urine to flow freely. One of the main consequences of this narrowing is the increased frequency of urination, as the bladder becomes more sensitive and tends to fill more quickly, leading to the urge to urinate even when the bladder isn't full.

As men age, hormonal changes also play a role in prostate enlargement, contributing to the prevalence of BPH. The condition is typically non-cancerous, but it can greatly impact quality of life due to frequent trips to the bathroom, especially at night, which can affect sleep.

Other conditions like prostatitis, prostate cancer, and urinary tract infections can also cause urinary frequency, but they are associated with different symptoms and etiologies. Prostatitis may present with pain and inflammation, prostate cancer may not show symptoms until later stages, and urinary tract infections typically come with additional symptoms like pain and burning during urination. BPH is specifically notable for its significant impact on urinary frequency due to the mechanical obstruction caused by prostate enlargement.
