Benign prostatic hyperplasia (BPH) is a condition caused by an enlarged prostate gland. It is not cancerous, nor does it increase the risk of prostate cancer. However, it does affect millions of men as they age, and it can result in bothersome lower urinary tract symptoms (LUTS).
A urologic oncologist with ÐßÐßÊÓÆµ explains what causes BPH and how to treat BPH.
BPH becomes increasingly common as men age:
While nearly 80% of men will develop BPH, only about 30% experience symptoms significant enough to need medical intervention.
What is the main cause of BPH? Age is the most significant risk factor for BPH. While the exact mechanism behind BPH is not fully understood, it has been linked to hormonal changes that occur as men age.
Other contributing factors may include:
The prostate sits under the bladder and surrounds the urethra. The prostate’s primary function is to produce the fluid that sperm travels through, also known as semen. The prostate can get bigger as men age, and it can obstruct the flow of urine, resulting in lower urinary tract symptoms.
It’s important to note that not all prostates are created equal, and a patient’s prostate size doesn’t always correlate with symptom severity. Some men with large prostates have no issues urinating, while some with smaller prostates do.
This variability means that symptoms can range from mild to severe, regardless of prostate size. So, it’s important to discuss any urinary changes with a doctor, even if you don’t think your prostate is enlarged.
BPH can cause various urinary symptoms, including:
These symptoms often develop gradually. Most men don’t notice day-to-day changes, but many do recognize differences when asked to compare their current urinary symptoms to their voiding habits in their 20s, our expert says.
It is important to communicate openly with your doctor about any urinary symptoms you are experiencing.
Consider these questions about your urinary health, and compare your answers to your experience when you were in your 20s:
One way to initiate the conversation with your doctor is to say: “Hey, I feel like there has been a change in my urinary stream.â€
Tools for diagnosing BPH typically include:
A bladder ultrasound checks the post-void residual (PVR), which is the amount of urine remaining in the bladder after urination.
It is important to differentiate BPH from other conditions with similar symptoms, because these conditions are treated differently.
According to our expert, one great mimicker of BPH that is often misdiagnosed is an overactive bladder. If the patient can empty their bladder completely as confirmed by a PVR but still complains of urgency and frequency, then it is more likely that they have an overactive bladder.
Doctors might also test a patient’s prostate-specific antigen (PSA) level to rule out prostate cancer.
Several significant advancements have been made in treatments for BPH in recent years, and there are many different ways of treating BPH.
Medications for BPH
Surgery for BPH
If medications fail, various surgical options are available. Modern surgical techniques have significantly improved patient outcomes, compared to early treatment options for BPH. Following surgery, most patients are able to go home the same day, with lower risks of complications like incontinence or erectile dysfunction.
Most patients who undergo prostate surgery for noncancerous purposes do not experience those effects, our expert adds.
No specific diets or supplements are proven to prevent or treat BPH. Overall health maintenance is advised instead.
If you’re experiencing urinary changes, discuss them with your doctor. BPH is manageable, and early intervention can improve your quality of life. BPH is common as men age, but remember:
Remember, your doctor is there to help you. Don’t be embarrassed to discuss these topics — they’re important for your health. By providing detailed information to your primary care physician or urologist, you help them make a more accurate diagnosis and recommend the most appropriate treatment or referral.
