Enlarged Prostate (BPH): Symptoms, Causes, Diagnosis and Treatment Options
An enlarged prostate, known medically as benign prostatic hyperplasia (BPH), is a common non-cancerous condition in which the prostate gland grows larger with age. As the gland enlarges, it can press on the tube that carries urine out of the body and lead to urinary symptoms such as a weak stream, difficulty starting, or a frequent need to urinate.
This page explains what BPH is, the symptoms it can cause, why the prostate enlarges, how the condition is diagnosed, and the main categories of treatment and management. It also describes situations in which urinary symptoms should be evaluated promptly by a healthcare professional. The goal is general education, not diagnosis or treatment advice.
Quick Overview
- What it is: A non-cancerous enlargement of the prostate gland that becomes more common with age.
- Common symptoms: Weak or interrupted urine stream, trouble starting, straining, dribbling, incomplete emptying, and more frequent or urgent urination, including at night.
- Not the same as cancer: BPH is distinct from prostate cancer, though both can occur and both become more common with age.
- Diagnosis: Based on medical history, a symptom review, a physical exam that may include a digital rectal exam, a urine test, and sometimes blood tests or additional studies.
- Management: Options range from watchful waiting to medication and, in some cases, minimally invasive or surgical procedures.
- Seek care promptly if: You cannot urinate at all, see blood in your urine, or have fever with urinary symptoms.
What Is an Enlarged Prostate?
The prostate is a small gland that sits below the bladder and surrounds the upper part of the urethra, the tube that carries urine and semen out of the body. It is part of the male reproductive system and helps produce fluid that nourishes and transports sperm.
Benign prostatic hyperplasia is an increase in the number of cells in the prostate, which makes the gland larger. Because the urethra passes through the prostate, an enlarged gland can narrow or compress this channel and change how the bladder empties. The word "benign" means the growth is not cancer and does not spread to other parts of the body.
How BPH differs from prostate cancer
BPH and prostate cancer are separate conditions. BPH is an overgrowth of normal prostate tissue and is not cancer. Prostate cancer is the growth of abnormal cells that can spread. A person can have BPH, prostate cancer, both, or neither. Urinary symptoms alone cannot tell these conditions apart, which is why evaluation by a healthcare professional is important. Having BPH has not been shown to cause prostate cancer.
Common Symptoms
Symptoms of an enlarged prostate are often grouped by whether they relate to storing urine or to passing it. Many men with an enlarged prostate have mild or no symptoms, and symptoms do not always get worse in a predictable way over time.
Urinating (voiding) symptoms
- A weak or slow urine stream
- Difficulty starting urination
- Straining to urinate
- A stream that starts and stops
- Dribbling at the end of urination
- A feeling that the bladder is not completely empty
Storage symptoms
- Needing to urinate more often than usual
- A sudden or urgent need to urinate
- Waking up one or more times at night to urinate (nocturia)
Less commonly, BPH can contribute to urinary tract infections, bladder stones, the inability to fully empty the bladder, or a sudden inability to urinate. Blood in the urine can occur but should always be evaluated, because it has other possible causes.
Why the Prostate Enlarges
The exact cause of BPH is not fully understood. It is closely linked to aging and to the hormonal changes that occur in the body over time. The prostate goes through a first period of growth in early puberty and a second, slower phase of growth that begins around age 25 and continues for much of adult life.
Factors associated with BPH
- Age. BPH is uncommon before age 40 and becomes progressively more common in later decades.
- Hormonal changes. Shifts in the balance of hormones, including testosterone and dihydrotestosterone, are thought to play a role in prostate growth.
- Family history. Having a close relative with BPH may increase the likelihood of developing it.
- Other health conditions. Obesity, type 2 diabetes, and heart and circulation problems have been associated with BPH in research studies.
These are associations rather than proven direct causes. Functioning testicles appear to be necessary for BPH to develop, which is part of why the condition is tied to lifelong hormonal activity.
How BPH Is Diagnosed
There is no single test for BPH. A healthcare professional generally reaches the diagnosis by combining a medical history, a review of urinary symptoms, and an examination, while ruling out other conditions that can cause similar symptoms.
Steps a clinician may use
- Symptom questionnaire. A standardized set of questions is often used to measure how severe and bothersome symptoms are and to track changes over time.
- Medical history. Questions about fluid intake, caffeine and alcohol, medications, and other medical conditions.
- Physical exam. This may include a digital rectal exam, in which a clinician feels the back of the prostate to estimate its size and check its surface.
- Urine tests. A urinalysis can look for infection, blood, or other signs that point to another cause.
- Blood tests. A prostate-specific antigen (PSA) test may be discussed. PSA can be elevated in BPH as well as in other prostate conditions, so results are interpreted in context.
- Additional studies. Depending on the situation, a clinician may measure urine flow, check how much urine remains after voiding, use ultrasound imaging, or perform cystoscopy to look inside the urethra and bladder.
The purpose of this workup is both to confirm that symptoms are consistent with BPH and to identify other possible explanations, such as infection, bladder problems, or prostate cancer.
Treatment and Management
Treatment for an enlarged prostate depends on how much the symptoms affect daily life, whether complications are present, and a person's overall health and preferences. Options generally fall into the categories below, and decisions are made together with a healthcare professional.
Watchful waiting and lifestyle measures
When symptoms are mild and not bothersome, a clinician may recommend regular monitoring rather than active treatment. Some people are also advised to adjust the timing of fluids, limit caffeine and alcohol, avoid medications that can worsen symptoms when possible, and take time to empty the bladder fully. These measures do not shrink the prostate.
Medications
Several classes of prescription medication are used for BPH. Some relax the muscle in the prostate and bladder neck to ease urine flow, and others act on hormones to gradually reduce prostate size over months. Combinations are sometimes used. Each option has possible side effects that a prescriber will review. This page does not recommend any specific medication.
Procedures and surgery
When symptoms are more severe, do not respond to medication, or cause complications, a range of minimally invasive and surgical procedures can remove or reduce the prostate tissue that is blocking urine flow. These vary in how they are performed, recovery time, and potential effects. A urologist can explain which approaches are appropriate for a given situation.
When to Seek Medical Care
Talk with a healthcare professional if urinary symptoms are bothering you, are getting worse, or are affecting your sleep or daily activities, even if they seem minor. An evaluation can identify the cause and rule out other conditions.
Seek prompt or emergency care if you have:
- A complete inability to urinate
- Painful, frequent, or urgent urination with fever, chills, or body aches
- Blood in the urine
- Lower abdominal or urinary tract pain
- Urine that is cloudy or has a strong odor along with other symptoms
A sudden and complete inability to pass urine, known as acute urinary retention, is a medical emergency. For any medical emergency, contact your local emergency services.
Frequently Asked Questions
Is an enlarged prostate the same as prostate cancer?
No. Benign prostatic hyperplasia is a non-cancerous increase in prostate size. It is a different condition from prostate cancer, although both can occur in the same person and both become more common with age. Only a healthcare professional can determine the cause of prostate or urinary symptoms.
Does an enlarged prostate always need treatment?
Not always. When symptoms are mild and not bothersome, a healthcare professional may recommend monitoring over time rather than starting medication or a procedure. Treatment decisions depend on how much symptoms affect daily life and whether complications are present.
Can lifestyle changes help with BPH symptoms?
Some people find that adjusting fluid timing, limiting caffeine and alcohol, and fully emptying the bladder can reduce the impact of urinary symptoms. These steps do not shrink the prostate, and they are not a substitute for medical evaluation. Discuss any changes with a healthcare professional.
When are urinary symptoms an emergency?
A sudden and complete inability to urinate, along with pain and a full bladder, is called acute urinary retention and needs urgent medical attention. Blood in the urine, fever with urinary symptoms, or severe pain also warrant prompt care.
Does Men's Prostate Check provide medical advice or diagnosis?
