What is a common symptom of benign prostatic hyperplasia (BPH)?

Benign prostatic hyperplasia (BPH) is a condition characterized by the enlargement of the prostate gland, which is commonly seen in older men. A primary symptom associated with BPH is urinary obstruction, which occurs due to the prostate pressing against the urethra as it expands. This pressure can lead to various urinary symptoms, including difficulty starting urination, a weak urinary stream, and frequent urination, especially at night (nocturia). These symptoms signify that the enlarged prostate is obstructing normal urine flow, making urinary obstruction the hallmark symptom of BPH.

In contrast, the other options do not typically relate to BPH. A rash may suggest an allergic reaction or another dermatological issue rather than a prostate condition. Weight loss could be attributed to numerous other health concerns, but it is not a common symptom of BPH. Severe abdominal pain is also not characteristic of BPH; instead, it is commonly associated with conditions involving acute abdominal or pelvic issues, which are separate from the typical urinary complications arising from BPH.
