Does the prostate get smaller with age? Separating myth from reality

According to the Urology Care Foundation, benign prostatic hyperplasia (BPH) affects up to 80% of men by age 85, a condition where the prostate grows larger, not smaller. This directly contradicts the common misconception regarding the question: does the prostate get smaller with age?

Quick Summary

The prostate typically does not get smaller with age; instead, it often grows larger due to benign prostatic hyperplasia (BPH), a non-cancerous condition affecting most older men and causing urinary symptoms.

Key Points

• Prostate Enlargement is Common: The prostate typically grows, not shrinks, with age, in a process known as benign prostatic hyperplasia (BPH).

• Hormonal Changes are a Factor: Age-related hormonal shifts, particularly involving dihydrotestosterone (DHT), are believed to cause the prostate to enlarge.

• Urinary Symptoms are a Key Sign: An enlarged prostate can cause urinary issues like weak flow, frequent urination, and difficulty starting urination by compressing the urethra.

• BPH is Not Cancer: It is important to distinguish BPH, a non-cancerous condition, from prostate cancer, although both are more common in older men [1.2.3, 1.3.3, 1.4.2, 1.5.2, 1.7.3, 1.9.3, 1.4.5, 9.10].

• Many Treatment Options Exist: Management for BPH ranges from simple lifestyle changes and medication to minimally invasive procedures and surgery [1.2.3, 1.3.3, 1.4.2, 1.5.2, 1.7.3, 1.9.3, 1.4.5, 9.10].

• Early Consultation is Best: If you experience persistent urinary symptoms, consulting a healthcare provider is crucial for proper diagnosis and treatment [1.2.3, 1.3.3, 1.4.2, 1.5.2, 1.7.3, 1.9.3, 9.10].

What is Benign Prostatic Hyperplasia (BPH)?

Benign Prostatic Hyperplasia (BPH) is a common, non-cancerous enlargement of the prostate gland prevalent in many aging men. This growth can compress the urethra, leading to various urinary problems. BPH is considered a normal part of aging and is distinct from prostate cancer.

Why the Prostate Tends to Grow with Age

The exact causes of BPH are not fully understood, but hormonal changes in aging men are strongly implicated. The hormone dihydrotestosterone (DHT) plays a significant role in stimulating prostate cell growth. Changes in testosterone and estrogen levels over time may also contribute. This cellular increase leads to prostate enlargement.

Common Symptoms of an Enlarged Prostate

Pressure from an enlarged prostate on the urethra can cause lower urinary tract symptoms (LUTS). These symptoms can include a weak or slow urinary stream, difficulty starting urination, interrupted urine flow, frequent urination (especially at night), incomplete bladder emptying, sudden urges to urinate, and dribbling after urination.

Comparing Normal vs. Enlarged Prostate

Feature	Normal Prostate	Enlarged Prostate (BPH)
Size	Small (walnut-sized)	Larger (can be lemon-sized or more)
Growth	Two growth phases	Third, continuous growth phase in middle age
Urethra	Not compressed	Compressed and narrowed
Urinary Flow	Normal, strong	Weak, hesitant, or interrupted
Bladder	Empties completely	May not empty completely
Symptoms	No significant urinary issues	Can cause bothersome symptoms

Lifestyle Modifications for Managing BPH Symptoms

Simple lifestyle changes can help manage mild to moderate BPH symptoms [1.2.3, 1.3.3, 1.4.2, 1.5.2, 1.7.3, 1.9.3, 7.8]. These include timed voiding, double voiding, reducing fluid intake before bed, limiting caffeine and alcohol, staying active, and avoiding certain medications that can worsen symptoms [7.8].

When to Seek Medical Help

Persistent or worsening urinary symptoms warrant evaluation by a healthcare provider, such as a urologist, to rule out other conditions and determine appropriate treatment [1.2.3, 1.3.3, 1.4.2, 1.5.2, 1.7.3, 1.9.3, 9.10].

Medical and Surgical Treatments for BPH

Medical interventions may be necessary for more severe symptoms [1.2.3, 1.3.3, 1.4.2, 1.5.2, 1.7.3, 1.9.3, 9.10]. Options include medications like alpha-blockers and 5-alpha reductase inhibitors, or combination therapy. Surgical procedures such as TURP, UroLift, Rezum therapy, and laser therapy are also available to remove excess tissue or open the urethra [1.4.5, 9.10].

Conclusion

The prostate typically grows larger with age, rather than smaller, a common condition called BPH. Understanding this helps in managing its effects. Consult a healthcare professional if experiencing urinary symptoms.

Frequently Asked Questions

Does benign prostatic hyperplasia (BPH) increase the risk of prostate cancer?

No, BPH is not a risk factor for prostate cancer. Both are common in aging men and can cause similar symptoms, but they are separate conditions requiring different management [1.2.3, 1.3.3, 1.4.2, 1.5.2, 1.7.3, 1.9.3, 1.4.5, 9.10].

Is an enlarged prostate a sign of aging?

Yes, an enlarged prostate is very common as men get older, with risk increasing after age 50. It's considered a normal part of the aging process for many men.

Can diet affect prostate size?

While diet doesn't directly cause BPH, a healthy diet rich in fruits/vegetables and low in red meat/saturated fat may support overall prostate health and manage symptoms. Some studies link obesity to higher BPH risk [1.2.3, 1.3.3, 1.4.2, 1.5.2, 1.7.3, 1.9.3, 7.8].

Can lifestyle changes reverse prostate enlargement?

Lifestyle changes cannot reverse prostate enlargement, but they can be effective in managing and reducing the severity of associated urinary symptoms, such as limiting caffeine, alcohol, and managing fluid intake [1.2.3, 1.3.3, 1.4.2, 1.5.2, 1.7.3, 1.9.3, 7.8].

What is the primary cause of prostate growth with age?

The primary cause is believed to be hormonal changes, specifically the continued effect of dihydrotestosterone (DHT) within the prostate as men age.

When should a man see a doctor about prostate symptoms?

Consult a doctor if you have persistent or bothersome urinary symptoms like a weak stream, frequent urination, or difficulty urinating. Early evaluation helps rule out serious conditions and explore treatment [1.2.3, 1.3.3, 1.4.2, 1.5.2, 1.7.3, 1.9.3, 9.10].

Is it possible for the prostate to shrink?

Yes, certain medications (like 5-alpha reductase inhibitors such as finasteride or dutasteride) are designed to shrink the prostate for BPH treatment. Some surgical procedures also remove tissue to reduce size.
