Final answer:
The treatment options for a 55-year-old male with irritative and obstructive urinary symptoms caused by benign prostatic hyperplasia (BPH) include medication for mild to moderate symptoms and surgery for severe enlargement.
Step-by-step explanation:
For a 55-year-old male presenting with irritative and obstructive urinary symptoms, the likely cause is benign prostatic hyperplasia (BPH). BPH is the abnormal growth of the prostate gland, which constricts the urethra, leading to urinary symptoms. Treatment options for BPH include medication for mild to moderate symptoms, and surgery to remove a portion of the prostate tissue for severe enlargement. It's important for the individual to consult with a healthcare provider to determine the most appropriate treatment plan.
