Benign prostatic hyperplasia (BPH), or an enlarged prostate, is a common condition in aging men where the prostate gland grows larger than usual. Symptoms may include frequent urination, urgency, weak urine stream, and difficulty starting or stopping urination. While not cancerous, BPH can cause bothersome urinary symptoms and affect quality of life. Diagnosis involves a physical exam, including a digital rectal exam, and possibly imaging tests. Treatment options range from watchful waiting to medications or procedures to relieve symptoms and improve urinary flow. Lifestyle changes, such as limiting caffeine and alcohol, may also help manage symptoms.
