What are signs and symptoms of benign prostatic hyperplasia (BPH)?

Benign prostatic hyperplasia (BPH) is a common condition in older men characterized by the enlargement of the prostate gland, which can lead to various urinary symptoms. The correct choice highlights the hallmark signs associated with this condition, such as difficulty urinating, a weak urine stream, and increased urinary frequency.

Difficulty urinating is primarily due to the enlarged prostate pressing against the urethra, obstructing the flow of urine. This obstruction may result in a weak urine stream, as the weakened flow is a direct consequence of the pressure exerted on the urethra. Additionally, increased urinary frequency occurs because the bladder may need to contract more often in response to the impaired outflow of urine.

In contrast, the other options describe symptoms that do not align with the presentation of BPH. Symptoms like pain during urination and fever typically suggest an infection or other acute conditions rather than the gradual onset associated with BPH. Similarly, loss of appetite and fatigue as well as frequent headaches and dizziness point towards systemic issues or other unrelated medical conditions rather than the specific urinary manifestations of benign prostatic hyperplasia.
