Benign Prostatic Hyperplasia
What is Benign Prostatic Hyperplasia?
Benign prostatic hyperplasia is a noncancerous enlargement of the prostate gland. The prostate is a small, walnut-shaped gland that sits below the bladder and surrounds the urethra, the tube that carries urine out of the body. As men age, the prostate naturally grows larger.
When the prostate gets too large, it can squeeze the urethra and make it harder to urinate. This happens gradually over time. BPH is one of the most common health issues in men over 50. About half of men in their 60s have some BPH symptoms, and that number rises to 90% by age 85.
BPH is not cancer and does not increase your risk of prostate cancer. However, it can affect your quality of life if left untreated. The good news is that many treatment options exist, from lifestyle changes to medications and procedures.
Symptoms
- Frequent urination, especially at night
- Difficulty starting urination or weak urine stream
- Stopping and starting while urinating
- Feeling like your bladder is not completely empty
- Urgent need to urinate that is hard to control
- Dribbling at the end of urination
- Straining to urinate
- Inability to urinate in severe cases
Some men with BPH have mild symptoms that do not bother them much. Others find symptoms significantly affect their daily lives and sleep. Symptom severity does not always match prostate size. A man with a very large prostate might have few symptoms, while another with a slightly enlarged prostate could have major issues.

Causes and risk factors
BPH is caused by hormonal changes that occur with aging. As men get older, the balance of hormones in the body shifts. Levels of testosterone decrease while other hormones like estrogen remain stable. This hormonal change may trigger prostate cells to grow. The exact reason why some men develop BPH and others do not is still not fully understood.
Risk factors include aging, family history of BPH, diabetes, heart disease, and obesity. Men who are physically inactive or have excess belly fat are at higher risk. Certain ethnic backgrounds also show higher rates. Asian men tend to have lower rates of BPH than white or Black men.
How it's diagnosed
Doctors diagnose BPH through a physical exam, medical history, and testing. A digital rectal exam lets your doctor feel the size and shape of your prostate. You may also complete a questionnaire about your symptoms and how they affect your life.
Blood tests can help rule out other conditions. A PSA test measures prostate-specific antigen, a protein made by the prostate. Elevated PSA can indicate BPH, but it can also signal prostate cancer or inflammation. Other tests might include a urine test, ultrasound, or urine flow study. Talk to your doctor about which tests are right for you based on your symptoms and risk factors.
Treatment options
- Watchful waiting for mild symptoms that do not interfere with daily life
- Limit fluids before bedtime and reduce caffeine and alcohol intake
- Practice double voiding by urinating, waiting a moment, then trying again
- Alpha-blockers like tamsulosin or doxazosin to relax prostate muscles
- 5-alpha reductase inhibitors like finasteride to shrink the prostate
- Combination therapy using both types of medications
- Minimally invasive procedures to remove or reduce prostate tissue
- Surgery for severe cases that do not respond to other treatments
- Saw palmetto and other herbal supplements, though evidence is mixed
Frequently asked questions
BPH is a noncancerous enlargement of the prostate gland that happens naturally with aging. Prostate cancer involves malignant cells that can spread to other parts of the body. Having BPH does not increase your risk of developing prostate cancer. Both conditions can cause elevated PSA levels, which is why additional testing is often needed to determine the cause.
BPH typically begins in men over age 40, but symptoms usually appear after age 50. By age 60, about half of men have some degree of BPH. By age 85, about 90% of men have symptoms. The prostate continues to grow throughout a man's life, but not all men develop bothersome symptoms.
Yes, lifestyle changes can help manage mild to moderate BPH symptoms. Try limiting fluids before bedtime, reducing caffeine and alcohol, and urinating on a schedule rather than waiting for urgency. Exercise and maintaining a healthy weight may also help. Some men find that avoiding decongestants and antihistamines reduces symptoms because these medications can tighten bladder muscles.
PSA is a protein produced by the prostate gland that can be measured with a blood test. An elevated PSA level can indicate BPH because a larger prostate produces more PSA. PSA alone cannot diagnose BPH because elevated levels can also indicate prostate cancer, infection, or inflammation. Your doctor will use PSA results along with other tests and symptoms to make a diagnosis.
BPH symptoms typically progress slowly over many years. Some men notice gradual worsening while others remain stable for long periods. A small percentage experience sudden worsening of symptoms. Regular checkups help your doctor monitor any changes and adjust treatment as needed.
If left untreated, severe BPH can lead to kidney damage in some cases. When urine cannot drain properly from the bladder, it can back up into the kidneys and cause pressure. This is rare but serious. Symptoms like complete inability to urinate, blood in urine, or bladder stones require immediate medical attention.
No, not all men with an enlarged prostate need treatment. If symptoms are mild and not affecting your quality of life, watchful waiting may be appropriate. Your doctor will monitor your condition with regular checkups. Treatment becomes necessary when symptoms interfere with daily activities, sleep, or overall wellbeing.
Alpha-blockers typically provide symptom relief within a few days to weeks. These medications relax the muscles around the prostate and bladder neck. 5-alpha reductase inhibitors take longer, usually 3 to 6 months, because they work by shrinking the prostate. Some men take both types of medications for better results.
BPH procedures are generally safe, but complications can occur. Possible risks include bleeding, infection, difficulty urinating temporarily, and retrograde ejaculation where semen enters the bladder instead of exiting the penis. Most men experience significant symptom improvement after surgery. Discuss specific risks and benefits with your doctor based on your individual situation.
Some research suggests diet may play a role in BPH symptoms. Diets high in fruits, vegetables, and healthy fats may be protective. Limiting red meat and high-fat dairy products might help. Maintaining a healthy weight through diet and exercise is beneficial. While no specific diet cures BPH, healthy eating supports overall prostate health.
