December 17, 20245 min read

Introduction

An enlarged prostate is a common condition that affects many men, especially as they get older. But why does it happen? What causes an enlarged prostate, what symptoms should you watch for, and why does it interfere with urination? If you’re wondering, you’re not alone.

In this blog, we’ll answer 10 essential questions about why an enlarged prostate occurs and what you can do about it. You’ll find clear, easy-to-understand explanations, trusted links for further learning, and actionable steps. If you’re concerned about symptoms, it’s important to talk to a specialist for the right advice and treatment.


1. Why does an enlarged prostate occur?

The prostate is a small, walnut-sized gland that sits below the bladder and surrounds the urethra. As men age, it’s normal for the prostate to grow larger. This condition is called Benign Prostatic Hyperplasia (BPH), and it’s not cancerous.

The exact cause of BPH isn’t fully understood, but hormonal changes, particularly changes in testosterone and dihydrotestosterone (DHT), are believed to play a role.

2. Why does an enlarged prostate cause urinary obstruction?

When the prostate enlarges, it presses against the urethra (the tube that carries urine out of the body). This pressure can make it difficult for urine to flow normally, leading to:

  • Weak or slow urine flow

  • Trouble starting or stopping urination

  • Frequent need to urinate, especially at night

The obstruction happens because the growing prostate squeezes the urethra, creating a narrow pathway for urine to pass through.

3. What are the most common symptoms of an enlarged prostate?

An enlarged prostate causes symptoms that can affect your daily life. The most common symptoms include:

  • Frequent urination, especially at night

  • Weak urine flow

  • Difficulty starting and stopping urination

  • A feeling that your bladder isn’t empty

  • Urinary urgency (a sudden strong need to urinate)

These symptoms worsen over time if left untreated. It’s essential to consult a urologist to assess your condition and explore treatment options.


4. Why does the prostate gland grow as men age?

The prostate grows throughout a man’s life, but significant growth usually happens after age 40. This growth is linked to changes in testosterone levels. As men age, testosterone levels drop, but levels of DHT (a by-product of testosterone) remain higher. DHT causes the prostate cells to grow, leading to an enlarged prostate.

It’s a natural part of aging, but not all men experience severe symptoms.

5. How does an enlarged prostate interfere with urination?

The prostate surrounds the urethra, so when it grows larger, it can squeeze or partially block this tube. This makes it harder for urine to pass through, leading to problems like:

  • Slow or weak urine stream

  • Straining to urinate

  • Dribbling at the end of urination

  • Urinary retention (inability to fully empty the bladder)

Over time, untreated BPH can cause bladder damage.


6. What lifestyle factors can worsen an enlarged prostate?

Certain habits and lifestyle choices can make BPH symptoms worse. These include:

  • Drinking too much fluid, especially before bedtime

  • Consuming caffeine and alcohol

  • Sitting for long periods

  • Certain medications, like decongestants, that tighten the urethra

Small changes, such as reducing caffeine intake and staying active, can improve symptoms. Talk to your doctor about a plan tailored to you.


7. Why is surgery sometimes needed for an enlarged prostate?

Surgery for an enlarged prostate is only recommended when symptoms are severe and do not improve with medication or lifestyle changes. This may include:

  • Severe urinary obstruction

  • Bladder stones

  • Repeated urinary tract infections (UTIs)

Procedures like TURP (Transurethral Resection of the Prostate) or laser therapy can remove part of the prostate and relieve symptoms.

8. Can an enlarged prostate be prevented?

While you can’t completely prevent prostate growth, you can reduce your risk of severe symptoms by:

  • Maintaining a healthy weight

  • Exercising regularly

  • Eating a balanced diet rich in vegetables, whole grains, and healthy fats

  • Reducing stress

These steps support overall prostate health and can help slow the progression of BPH.


9. Why is an MRI sometimes used to check for prostate issues?

An MRI (Magnetic Resonance Imaging) is sometimes used to get a detailed look at the prostate. It helps doctors assess the size of the prostate and rule out other conditions like prostate cancer.

While BPH is not cancer, an MRI can help specialists make a clear diagnosis and plan the right treatment.

10. When should you see a prostate specialist?

If you have any symptoms of an enlarged prostate, it’s important to see a specialist. A prostate specialist, also known as a urologist, can:

  • Diagnose your condition through tests like PSA levels, ultrasound, or an MRI

  • Provide the right treatment options, from medications to surgery

  • Monitor your symptoms over time

Ignoring symptoms can lead to complications, so don’t delay getting help.
