Benign prostatic hyperplasia can lead to difficulty in what bodily function?

Benign prostatic hyperplasia (BPH) is a common condition in older men where the prostate gland enlarges, leading to various urinary symptoms. The correct choice, urination, is associated with BPH because as the prostate enlarges, it can compress the urethra, the tube through which urine passes. This compression can result in difficulties such as a weak urine stream, increased frequency of urination, urgency, and even inability to fully empty the bladder.

The other options—breathing, digestion, and circulation—are not directly affected by BPH, as the condition specifically relates to the urinary tract and prostate gland's influence on bladder function. Thus, the primary issue arising from benign prostatic hyperplasia is indeed difficulty in urination.
