It's natural for the prostate to grow with age. However, when it affects how you urinate, MU Health Care offers expert care and treatment options for an enlarged prostate, also known as benign prostatic hyperplasia (BPH).
BPH is characterized by an enlarged prostate putting too much pressure on the urethra. That pressure can slow or block urine flow and change how often or easily you go to the bathroom.
BPH affects approximately 50% of men ages 51-60. This percentage increases with age, affecting as many as 80% of men in their 70s and 80s.
BPH isn’t cancer and doesn’t raise your risk for prostate cancer, but it can get worse over time and negatively affect the bladder and urethra.
At MU Health Care, our board-certified urologists tailor your care to fit your needs. We’ll walk you through treatment options so you can choose what works best for your health goals.
Benign Prostatic Hyperplasia Symptoms
BPH affects everyone differently. It’s common for men to have no symptoms — or symptoms that seem mild enough to ignore. However, issues like urinary tract infections or bladder muscle damage can still develop over time. The most common symptoms of BPH include:
- Frequent urination: Needing to go more than eight times during the day.
- Nocturia: Waking up at night to urinate.
- Weak stream: Trouble starting, or a stream that feels slow or weak.
- Urgency or leakage: Sudden urges or difficulty holding it in.
- Discomfort: Straining or discomfort while urinating.
- Incomplete emptying: Feeling like the bladder doesn’t fully empty.
- Urinary retention: In severe cases, you may not be able to urinate at all.
Not all male urinary symptoms are due to BPH. Other conditions, such as diabetes, neurologic conditions, medication side effects, bladder conditions and more, can cause similar symptoms. This is why a comprehensive evaluation is necessary.
When to Seek Care for Benign Prostatic Hyperplasia
Even if symptoms seem minor, BPH can lead to complications like bladder damage or infections if left untreated.
Don’t ignore urinary changes or assume they’re just part of getting older. Talk to your doctor if you’re noticing symptoms.
Importantly, if you suddenly can’t urinate or can barely go, seek medical help right away.
Causes of Benign Prostatic Hyperplasia
BPH is a complex condition with multiple contributing factors. While the exact cause isn’t well understood, several factors may increase your risk:
- Aging: BPH becomes more common as men get older, though not all men develop it.
- Hormonal changes: Shifts in testosterone and DHT levels may play a role in prostate growth.
- Family history: Having a close relative with BPH may raise your chances of developing it.
- Lifestyle factors: Obesity, inactivity and poor diet can increase your risk.
- Related conditions: Diabetes, metabolic syndrome and long-term prostate inflammation may contribute to BPH.
How We Diagnose Benign Prostatic Hyperplasia
Prostate size is measured by volume in milliliters (mL). In general, a prostate larger than 30 mL (about the size of a ping pong ball) is considered enlarged. Prostates can enlarge all the way up to 500mL in size (about the size of a softball).
At MU Health Care, we start by reviewing your medical history, discussing your goals and performing a physical exam. Since urinary symptoms can have more than one cause, we’ll check for other possible conditions, too.
We may use several tools to diagnose BPH and personalize treatment options to your individual anatomy, history and goals, including:
- Blood and urine tests to check for infections or rule out other causes.
- Symptom questionnaires that evaluate how much your symptoms affect your daily life.
- Prostate-specific antigen (PSA) test to screen for prostate-related issues.
- Urine flow rate test to measure how quickly and fully you empty your bladder.
- Imaging tests like ultrasound, CT or MRI assess the size of your prostate.
- Cystoscopy, using a small camera to look inside your bladder and urethra for blockages or other problems.
