Enlarged Prostate (BPH): Symptoms, Red Flags and Treatment Options Compared

By ValueReviewHub Editorial · Sources checked September 28, 2026 · How we review

Benign prostatic hyperplasia (BPH), an enlarged prostate that is not cancerous, is one of the most common reasons men start having urinary trouble as they age. According to the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), BPH affects 5% to 6% of men aged 40 to 64 and 29% to 33% of men aged 65 and older. This guide explains the symptoms, the red flags that need urgent care, and how the treatment options compare with the prostate supplements sold online.

What is BPH?

The prostate is a small gland below the bladder that surrounds the urethra, the tube that carries urine out of the body. As it enlarges with age, it can press on the urethra and affect the bladder, causing urinary symptoms. BPH is not cancer. But prostate cancer and other conditions can cause similar symptoms, which is why urinary changes should be checked by a clinician rather than self-treated.

Common symptoms

Trouble starting to urinate, or a feeling that the bladder isn’t empty
A weak or interrupted stream, or dribbling at the end
Waking at night to urinate (nocturia)
Urgent or frequent urination
Pain during urination

Get medical care right away (NIDDK) if you cannot urinate at all, have painful, frequent and urgent urination with fever and chills, see blood in your urine, or have severe pain in your lower abdomen or urinary tract.

How BPH is evaluated

A clinician will usually ask about symptoms, often using a standard questionnaire, and may examine the prostate, test your urine and discuss blood tests such as PSA. Depending on the findings, you may be offered tests of urine flow or bladder emptying, or a referral to a urologist.

Treatment options compared

Approach	What it involves	Evidence
Watchful waiting and lifestyle changes	Less fluid before bed, less caffeine and alcohol, timed bathroom visits, reviewing medicines that affect urination	Often enough for mild symptoms
Prescription medicines	Drugs that relax prostate muscle or shrink the gland, used alone or together	Proven in clinical trials; your doctor weighs side effects
Minimally invasive procedures and surgery	Various procedures to relieve blockage	For moderate to severe symptoms or complications
Saw palmetto and other supplements	Herbal products marketed for “prostate support”	NCCIH: saw palmetto is “probably not helpful” for BPH symptoms. Details

A word on prostate supplements

Online prostate formulas often promise to “shrink” the prostate or end night-time urination. Large NIH-funded trials of saw palmetto, the most popular ingredient, found no improvement in BPH symptoms, even at triple doses. Before buying any prostate supplement, have your symptoms assessed. Delaying care can let complications such as urinary retention develop, and can delay the diagnosis of other conditions.

Practical tips that can help

Spread fluids through the day and cut back in the 2 hours before bed.
Limit caffeine and alcohol, which can increase urgency.
Ask your pharmacist whether any of your medicines, such as some decongestants or antihistamines, may worsen urinary symptoms.
Stay active and manage weight. General health affects urinary symptoms.

FAQ

Does BPH turn into prostate cancer?

BPH is a non-cancerous condition. Because symptoms can overlap with other conditions, including prostate cancer, discuss any urinary changes with a clinician.

Can supplements shrink an enlarged prostate?

There is no good evidence that over-the-counter supplements shrink the prostate. Saw palmetto did not improve symptoms in large trials.
