What are the early warning signs of benign prostatic hyperplasia?

What are the early warning signs and symptoms of benign prostatic hyperplasia (BPH) that men should watch for, and when should these changes prompt a medical evaluation?

Benign Prostatic Hyperplasia (BPH) is a gradual, non-cancerous enlargement of the prostate gland that often develops in older men, and its early warning signs usually involve changes in urination. Common symptoms include frequent urination, especially at night (nocturia), a weak or slow urine stream, difficulty starting urination, and a feeling that the bladder is not completely empty after passing urine. Some men may also notice urgency, where they feel a sudden need to urinate, or dribbling at the end of urination. As the condition progresses, these symptoms can become more noticeable and start affecting sleep and daily comfort. Medical evaluation is generally recommended when urinary changes become persistent, worsen over time, interfere with daily activities or sleep, or are accompanied by more concerning signs such as pain, blood in the urine, or sudden inability to urinate.
