Benign prostatic hyperplasia — better known as BPH or an enlarged prostate — is one of the most common conditions affecting men as they age. By the time a man reaches his sixties, there’s a greater than 50% chance he has some degree of prostate enlargement. By his eighties, that number climbs above 90%.
Yet despite how common it is, many men suffer in silence for years before seeking help. They assume slow urinary flow or frequent nighttime trips to the bathroom are simply part of getting older. They are not. BPH is a treatable medical condition, and ignoring it can lead to serious complications including urinary tract infections, bladder damage, and in severe cases, kidney problems.
What Causes BPH?
The prostate gland surrounds the urethra — the tube that carries urine out of the bladder. As the prostate grows, it squeezes the urethra and restricts urine flow. The exact cause of this growth isn’t fully understood, but hormonal changes as men age — particularly shifts in the balance between testosterone and estrogen — appear to play a central role.
Recognizing the Symptoms
BPH symptoms fall into two categories: obstructive and irritative. Obstructive symptoms include a weak or interrupted urine stream, straining to urinate, a feeling that the bladder hasn’t emptied completely, and dribbling at the end of urination. Irritative symptoms include frequent urination (especially at night, a condition called nocturia), sudden urgent need to urinate, and difficulty starting urination.
Not all men experience all symptoms, and the severity of symptoms doesn’t always correlate with the size of the prostate. Some men with significantly enlarged prostates have mild symptoms; others with only moderately enlarged glands suffer considerably.
Diagnosis
Diagnosing BPH involves a thorough history, a digital rectal exam (DRE) to feel the prostate, a PSA blood test to help rule out prostate cancer, and often an ultrasound to measure prostate volume and check for residual urine in the bladder. A urine flow rate test (uroflowmetry) measures how fast and how much urine is released.
Modern Treatment Options
Treatment depends on the severity of your symptoms and their impact on quality of life. For mild symptoms, watchful waiting with lifestyle changes — reducing fluid intake before bed, avoiding caffeine and alcohol, and double voiding — may be sufficient. For moderate to severe symptoms, alpha-blockers relax the muscles around the prostate and bladder neck, improving flow quickly. 5-alpha reductase inhibitors shrink the prostate over time. For men who prefer not to take daily pills, minimally invasive procedures offer excellent results. The Rezum procedure — a 15-minute in-office water vapor therapy — has become one of the most popular options. It requires no hospitalization, preserves sexual function, and provides lasting relief for most patients.
When to See a Urologist
Don’t wait until symptoms are severe. If you’re making more than two trips to the bathroom at night, if your stream is noticeably weak, or if you feel you can never fully empty your bladder — it’s time for an evaluation. Early treatment leads to better outcomes and prevents complications.
