Key facts

  • In a long-term trial, men on placebo still had a meaningful chance of BPH getting worse over several years1.
  • On average, urinary symptoms slowly got worse over several years2, though many men stayed stable; the risk of a sudden inability to urinate is higher with more severe symptoms, older age, or a larger prostate3.
  • In a long-term trial, 5-alpha reductase inhibitors reduced progression risk (including acute retention and invasive therapy); the alpha-blocker doxazosin reduced overall progression, and 5-ARIs can shrink the prostate somewhat1.
  • Watchful waiting is a recognized option for men with mild symptoms4.
  • Talk with your doctor before you decide. This information does not replace personal medical advice.

Does BPH go away on its own?

Usually not; BPH tends to be long-term rather than something that clears on its own. In a large, long-term trial, men who received a placebo (an inactive treatment used for comparison) still had a meaningful chance of the condition getting worse over several years1. Medicines called 5-alpha reductase inhibitors (5-ARIs) reduced that risk (including acute retention and invasive therapy) and can shrink the prostate somewhat. The alpha-blocker doxazosin reduced overall progression in the same trial but did not significantly reduce acute retention or invasive therapy1.

Questions to ask

  • Is my prostate likely to keep growing, or has it leveled off?
  • Would a medicine like a 5-alpha reductase inhibitor or an alpha-blocker fit my situation?
  • How would we know if a medicine is working for me?

Why this matters: Expecting BPH to resolve on its own can delay a conversation about medicines or watchful waiting that might help. For medicine options, see medication for BPH.

Does BPH get worse over time?

Community studies that followed men over time found that, on average, urinary symptoms slowly got worse over several years, though many men stayed stable2. The risk of a sudden inability to urinate (acute urinary retention) was higher in men with more severe symptoms, an enlarged prostate, or a slower urinary flow3.

Questions to ask

  • How severe are my symptoms now, and what would count as "worse" for me?
  • Based on my prostate size and flow, am I at higher or lower risk of retention?
  • What symptoms should prompt me to call before my next visit?

Why this matters: Knowing your own risk factors, age, symptom severity, and prostate size, can help you and your clinician decide how closely to watch things. A sudden inability to urinate, fever, or heavy bleeding needs urgent care, not a wait-and-see approach.

What does watchful waiting mean?

Watchful waiting is a recognized option for men with mild symptoms4. Watchful waiting, also called active surveillance5, generally means regular checkups instead of starting medicine or a procedure right away, along with habit changes such as limiting fluids before bed, cutting back on caffeine and alcohol, and avoiding medicines that can worsen symptoms5.

Questions to ask

  • Am I a reasonable candidate for watchful waiting, or do my symptoms already suggest treatment?
  • How often would we check in if I choose watchful waiting?
  • What would make you recommend moving to medicine or a procedure?

Why this matters: Watchful waiting is planned monitoring, not simply doing nothing. For medicine and procedure options if watchful waiting is not enough, see BPH treatment options and medication for BPH.

Common questions

Does BPH go away on its own?

Usually not; it tends to be long-term. In a long-term trial, men on placebo still had a meaningful chance of the condition getting worse over several years1. Five-alpha reductase inhibitors reduced that risk and can shrink the prostate somewhat; the alpha-blocker doxazosin reduced overall progression in the same trial1. Talk with your doctor before you decide.

Does BPH get worse over time?

It can. Community studies found that, on average, urinary symptoms slowly got worse over several years, though many men stayed stable2, and the risk of a sudden inability to urinate is higher with more severe symptoms, older age, or a larger prostate3. Talk with your doctor before you decide.

Can an enlarged prostate shrink?

Somewhat. In a long-term trial, medicines called 5-alpha reductase inhibitors reduced the risk of BPH getting worse and could shrink the prostate1. Talk with your doctor before you decide.

What is watchful waiting for BPH?

Watchful waiting, also called active surveillance5, means regular checkups and simple habit changes instead of starting medicine or a procedure right away. It is a recognized option for men with mild symptoms4. Talk with your doctor before you decide.

When does BPH need treatment?

Your clinician may suggest treatment when symptoms bother you enough or you face a higher risk of urinary retention3,4. If watchful waiting is not enough, medicines and office-based procedures are covered in the BPH treatment options and medication guides. Talk with your doctor before you decide.
