An enlarged prostate known medically as Benign Prostatic Hyperplasia (BPH)—is one of the most common conditions affecting men as they age. While it is not cancer, it can cause uncomfortable urinary symptoms and impact everyday life. Understand, what causes enlarged prostate, who is at risk, and how it is treated is key to protecting long-term prostate health.

What is an Enlarged Prostate?
The prostate is a small gland located below the bladder. As men get older, this gland naturally grows. When it becomes too large, it can press against the urethra and bladder, leading to difficulty passing urine and other symptoms. This non-cancerous growth of the prostate is called Benign Prostatic Hyperplasia (BPH).

What causes Enlarged Prostate?
The exact cause is not fully understood, but several key factors are known to contribute. Below are the main reasons what causes enlarged prostate becomes more likely:
- Ageing:
Age is the biggest factor. BPH is rare before the age of 40, but becomes increasingly common after 50. The hormonal changes especially in testosterone and dihydrotestosterone (DHT) stimulate prostate cell growth over time.
- Hormonal Imbalance:
The balance between male hormones (testosterone, DHT) and oestrogen shifts as men age. Increased DHT levels can cause the prostate gland to grow.
- Family History
If a close male relative (father or brother) has BPH, the chances of developing an enlarged prostate are significantly higher.
- Lifestyle and Health Conditions
Certain lifestyle factors increase risk, including lack of exercise,poor diet, excessive alcohol intake, smoking. Medical conditions such as diabetes, heart disease, obesity, and high blood pressure also play a vital role.
- Ethnicity
Studies show that African and Caribbean men may be at higher risk of developing prostate enlargement at a younger age.
- Inflammation or Prostatitis
Long-term inflammation may contribute to prostate enlargement in some men.
What are the common symptoms of an Enlarged Prostate?
Because the prostate surrounds the urethra, enlargement affects the flow of urine. The typical symptoms of an enlarged prostate include:
- Frequent urination, especially at night
- Weak urine flow
- Difficulty starting or stopping urination
- Feeling the bladder is not completely empty
- Sudden or urgent need to urinate
- Dribbling after finishing
These symptoms can affect sleep, work, and overall quality of life.

Is an enlarged prostate the same as Prostate Cancer?
No, BPH is not cancer and does not increase the risk of prostate cancer. However, the symptoms can be similar, so medical assessment is important if changes occur.
How is an enlarged prostate diagnosed?
A doctor may perform:
- Medical history & symptom review
- Prostate-specific antigen (PSA) blood test
- Digital rectal examination (DRE)
- Urine tests
- Bladder scan or ultrasound
This helps to confirm whether symptoms are caused by BPH or another condition.
What are the treatment options for an enlarged prostate?
The treatment options for an enlarged prostate depends on symptom severity.
- Lifestyle changes such as reducing caffeine and alcohol, limiting evening fluids, regular exercise, bladder training techniques
- Medications such as alpha-blockers (help relax prostate muscles), 5-alpha-reductase inhibitors (shrink prostate size), combination therapy
- Surgery (for severe cases) like traditional or laser surgery may be recommended when symptoms significantly affect daily life or bladder function.
How to reduce your risk of Prostate Enlargement?
Although ageing is unavoidable, you can support prostate health by:
- Maintaining a healthy weight
- Eating a balanced diet (rich in vegetables, low in processed foods)
- Staying physically active
- Managing blood pressure & blood sugar
- Avoiding smoking
- Regular prostate check-ups, especially after 50
Conclusion
In conclusion, understanding what causes an enlarged prostate empowers men to recognise symptoms early and seek appropriate care. While ageing and hormonal changes are the main factors, lifestyle and health conditions also play a significant role. With timely diagnosis and modern treatments, most men can manage symptoms effectively and maintain a good quality of life.
If you experience urinary changes or discomfort, speak to a healthcare professional for a proper assessment.
FAQs
1. What are three causes of an enlarged prostate?
Three common causes of an enlarged prostate include ageing, hormonal changes, and family history. As men get older, hormone levels shift—especially testosterone and DHT—which can stimulate prostate growth. Genetics also play a role, meaning men with a father or brother who had BPH are more likely to develop it themselves. Lifestyle factors such as obesity, diabetes, and lack of exercise can also contribute.
2. Can an enlarged prostate go back to normal?
An enlarged prostate does not usually shrink back to its original size naturally. However, symptoms can improve significantly with the right treatment. Medications, lifestyle changes, and minimally invasive procedures can reduce the size of the prostate or relax the muscles around it, helping many men feel much better even if the gland itself does not return to its previous size.
3. How can I reduce my prostate enlargement?
Prostate enlargement can be managed through healthy habits and medical treatment. Regular exercise, a balanced diet, maintaining a healthy weight, and limiting caffeine and alcohol can help reduce symptoms. Managing long-term conditions such as high blood pressure or diabetes also supports prostate health. If lifestyle changes are not enough, medications or modern prostate procedures can offer effective relief.
4. What are the 5 warning signs of an enlarged prostate?
The five key warning signs of an enlarged prostate are frequent urination (especially at night), a weak or slow urine flow, difficulty starting to urinate, a feeling that the bladder is not fully empty, and a sudden or urgent need to urinate. If any of these symptoms appear, it is important to seek medical advice for proper assessment and treatment.
5. Is an enlarged prostate the same as prostate cancer?
No, an enlarged prostate known as BPH is not the same as prostate cancer and does not increase the risk of developing cancer. Because some symptoms overlap, such as difficulty urinating or changes in flow, it is important to have any new urinary symptoms checked by a healthcare professional to rule out more serious conditions.
