What prostate symptoms should men over 50 watch for?

Dr Ravikumar Banavase Ramesh says frequent nighttime urination, weak urine flow and difficulty urinating after 50 may signal prostate problems. Blood in the urine or semen and pelvic pain warrant medical attention, while an inability to urinate is a medical emergency. He advises men to discuss their symptoms, family history and prostate screening with a urologist.
