My prostate weighs 51 grams. Residual urine after voiding was reported as 28% of the amount that was in my bladder before urinating. I also have to urinate about three times during the night. What holistic treatment can help?
Quick Answer
A prostate volume of about 51 g is enlarged, but it is not five times normal. A typical adult prostate is roughly 20–30 mL in volume, so 51 g represents a meaningful enlargement but not an unusually massive gland.
Your nighttime urination may be related to BPH, but nocturia can also be caused by overactive bladder, excessive nighttime urine production, sleep apnea, diabetes, medicines, leg swelling or other medical conditions.
The “28% residual” also needs clarification. Post-void residual urine is best interpreted as an actual volume in milliliters (mL). A percentage alone cannot tell us whether the residual is clinically important.
A sensible holistic plan combines lifestyle measures with proper medical assessment and, when needed, evidence-based medication. Herbs and foods should not be expected to reliably shrink a 51 g prostate.
Hello John,
Your results are consistent with possible benign prostatic enlargement, but prostate size by itself does not tell us how severe the obstruction is or which treatment you need.
Is a 51-Gram Prostate Very Large?
It is enlarged, but the old statement that a 51 g prostate is “around five times normal” was incorrect.
A normal adult prostate is commonly around 20–30 mL. In clinical practice, prostate volume above about 30 mL is generally considered enlarged.
A 51 g or approximately 51 mL prostate therefore represents a moderate degree of enlargement. More importantly, it places you above the prostate-volume thresholds used in major BPH guidelines when deciding whether medicines that actually reduce prostate size may be appropriate.
What Does “28% Residual Urine” Mean?
This result is difficult to interpret without the actual volume in milliliters.
For example:
- 28% of a 100 mL pre-void bladder volume is only 28 mL;
- 28% of a 300 mL pre-void volume is 84 mL; and
- 28% of a 500 mL pre-void volume is 140 mL.
Those are very different situations.
Current urological guidelines recommend measuring post-void residual (PVR) as an actual volume, usually with a bladder scan or ultrasound immediately after urination.
A high PVR can occur because the prostate is obstructing the bladder outlet, but it can also occur because the bladder muscle is not contracting strongly enough.
So I would ask your urologist for the actual post-void residual in mL rather than relying only on a percentage.
Does Waking Three Times at Night Mean the Prostate Is the Cause?
Not necessarily.
Waking three times to urinate is significant nocturia, but nocturia is often multifactorial.
Possible contributors include:
- BPH and bladder outlet obstruction;
- overactive bladder;
- producing too much urine during the night;
- large evening fluid intake;
- caffeine or alcohol;
- diuretic medicines;
- diabetes;
- obstructive sleep apnea;
- leg swelling that redistributes fluid when you lie down;
- heart or kidney disease; and
- sleep disorders in which you wake for another reason and then decide to urinate.
This is why a 3-day bladder diary is particularly useful. Record the time and amount of drinks and each urination, including the urine produced overnight.
What Would a Realistic “Holistic” BPH Plan Look Like?
I use the word holistic to mean that we address the whole clinical picture—not that we replace proven treatment with supplements.
A reasonable plan includes four parts:
- confirm what is causing the symptoms;
- use lifestyle measures that have a realistic chance of helping;
- use medication when the expected benefit outweighs the risks; and
- reserve procedures or surgery for men who need them.
1. Lifestyle Measures That Can Help
Move More Fluid Intake Earlier in the Day
If nighttime urination is a major problem, try to take most of your fluids earlier in the day and reduce unnecessarily large drinks during the 2 to 4 hours before bedtime.
Do not deliberately dehydrate yourself.
Review Caffeine and Alcohol
Caffeine can worsen urinary urgency and frequency in some men. Alcohol can increase urine production and disrupt sleep.
If either clearly worsens your symptoms, reduce the amount—especially later in the day.
Review Medication Timing
If you take a diuretic or “water tablet,” ask the prescribing clinician whether the timing is contributing to nighttime urination. Do not change prescription medicines yourself.
Manage Constipation
Constipation can worsen lower urinary tract symptoms by increasing pelvic pressure and interfering with normal bladder emptying.
Stay Physically Active
Regular physical activity supports cardiovascular and metabolic health and may also be associated with lower urinary symptom burden. It should be part of a healthy lifestyle even though exercise does not directly shrink the prostate.
Look for Sleep Apnea
If you snore loudly, stop breathing during sleep, wake choking or feel very sleepy during the day, tell your doctor. Sleep apnea is an important and commonly overlooked contributor to nocturia.
2. Medication May Be Particularly Relevant With a 51 g Prostate
This is where the prostate-size information becomes clinically useful.
Alpha Blockers
Medicines such as tamsulosin and other alpha blockers relax smooth muscle around the prostate and bladder neck. They can improve urine flow and symptoms relatively quickly, but they do not substantially shrink the prostate.
5-Alpha-Reductase Inhibitors
Finasteride and dutasteride can reduce prostate volume over time.
The European Association of Urology recommends 5-alpha-reductase inhibitors for men with moderate-to-severe lower urinary tract symptoms who have an increased risk of progression, for example a prostate volume greater than 40 mL.
Studies show these medicines can reduce prostate volume by approximately 18–28% over time and reduce the long-term risk of acute urinary retention and BPH-related surgery.
Combination Therapy
For men with bothersome symptoms and a larger prostate who are at increased risk of progression, an alpha blocker plus a 5-alpha-reductase inhibitor may sometimes provide both faster symptom relief and better long-term protection against progression than either strategy alone.
These decisions should be made with a clinician after reviewing symptom severity, flow rate, residual urine, blood pressure, sexual priorities and other medical conditions.
You can read more in our BPH medication guide.
3. Does a 51 g Prostate Mean You Need Surgery?
No.
Prostate size alone is not an indication for surgery.
Surgery is generally considered when symptoms remain significantly bothersome despite conservative or medical treatment, or when complications develop.
Important indications can include:
- recurrent or persistent urinary retention;
- recurrent urinary tract infections related to obstruction;
- bladder stones;
- recurrent visible bleeding attributed to BPH despite appropriate treatment;
- upper urinary tract dilation or kidney impairment due to obstruction;
- overflow incontinence from significant retention; or
- bothersome symptoms that remain inadequately controlled with other treatment.
If a procedure is needed, the choice depends on prostate anatomy, volume, median-lobe configuration, medical conditions, sexual-function priorities and local expertise.
Options now extend well beyond traditional TURP and include several minimally invasive and laser/enucleation techniques. See our BPH procedures and surgery guide.
Surgery Does Not Guarantee That Every Symptom Will Disappear
The old page promised that after surgery “all of the nasty symptoms will be gone.” That is too absolute.
When symptoms are truly caused by prostate obstruction, surgery can produce major improvements in urinary flow and symptom scores. But nocturia may persist if part of the problem comes from overactive bladder, nocturnal polyuria, sleep apnea, diabetes or another condition unrelated to the prostate.
This is another reason to establish the cause of the nighttime urination before choosing an invasive procedure.
Do Kegel Exercises Shrink the Prostate or Treat BPH?
No.
Pelvic floor exercises are useful for some forms of urinary incontinence, particularly after prostate surgery, but they do not reduce prostate volume or remove bladder outlet obstruction.
If your main problem is nocturia rather than urinary leakage, Kegel exercises would not be my primary BPH treatment.
Can Herbs Reduce a 51 g Prostate?
I would not promise this.
Pumpkin Seeds
Some pumpkin-seed preparations have shown modest improvement in lower urinary tract symptoms in clinical studies. However, they have not been shown to reliably shrink an enlarged prostate or prevent BPH progression.
See our page on pumpkin seeds and BPH.
Pygeum
There is limited older evidence suggesting short-term improvement in some urinary symptoms. The studies have generally been small and short and have used different preparations.
Pygeum has not been shown to provide the same proven prostate-size reduction and progression prevention as a 5-alpha-reductase inhibitor.
Saw Palmetto
High-quality reviews have found that saw palmetto used alone provides little or no meaningful benefit for BPH symptoms compared with placebo.
For a broader discussion, see our evidence-based guide to natural remedies for enlarged prostate.
What About Oysters?
Oysters are rich in zinc and can be part of a nutritious diet, but there is no established evidence that eating oysters treats BPH or shrinks an enlarged prostate.
Zinc is an essential nutrient, but more is not necessarily better. Routine high-dose zinc supplementation should not be used as a prostate treatment because excessive long-term intake can cause adverse effects, including copper deficiency.
Does BPH Turn Into Prostate Cancer?
No.
This is one of the most important corrections to the old answer.
BPH is a benign condition and does not increase a man’s risk of developing prostate cancer. BPH and prostate cancer can occur in the same man because both become more common with age, but one does not transform into the other.
Do You Need a PSA Test Every Three Months?
No—not simply because you have BPH.
PSA testing should be used according to the reason for testing: prostate-cancer screening, evaluation of a concerning clinical finding, follow-up of an abnormal PSA, or monitoring known prostate cancer.
Men considering PSA screening should discuss the benefits and harms with their clinician and choose an interval based on age, baseline PSA, family history, ancestry, genetic risk and previous results.
Testing every three months is not a standard schedule for uncomplicated BPH.
If you start finasteride or dutasteride, remember that these medicines can reduce PSA by approximately 50% after several months, so your doctor must take that effect into account when interpreting future results.
What I Would Ask Your Urologist Next
- What is my actual post-void residual in milliliters?
- What is my urinary flow rate?
- How severe are my symptoms on the International Prostate Symptom Score (IPSS)?
- Is the nocturia caused by prostate obstruction or by excessive nighttime urine production?
- Would a three-day bladder diary help?
- Given my approximately 51 g prostate, am I a candidate for a 5-alpha-reductase inhibitor?
- Would an alpha blocker or combination therapy make sense?
- Do I currently have any indication for a procedure, or is medical treatment more appropriate?
When to Seek Prompt Medical Care
- cannot urinate at all;
- develop fever or chills with urinary symptoms;
- have visible blood in your urine;
- develop severe bladder, flank or abdominal pain;
- develop rapidly worsening urinary retention; or
- are found to have kidney impairment or swelling of the kidneys related to obstruction.
A 51 g prostate is enlarged enough that I would take the finding seriously, but it does not automatically mean you need surgery. I would first clarify the actual post-void residual in milliliters, assess your urine flow and symptom score, and use a three-day bladder diary to understand why you are waking three times each night.
For a prostate of this size, it is reasonable to discuss medication that can reduce the risk of BPH progression—particularly a 5-alpha-reductase inhibitor if your overall findings support it. Lifestyle measures can help nocturia and symptom burden, but herbs, pumpkin seeds, oysters and Kegel exercises should not be presented as treatments that reliably shrink the prostate.
You also do not need PSA testing every three months simply because you have BPH, and BPH does not turn into prostate cancer.
