🧔 Prostate Health

Waking repeatedly at night to pass urine is one of the most common urinary concerns raised by men, and it has a medical name — nocturia. It does not automatically indicate anything serious, but it is a symptom worth understanding rather than dismissing as 'just ageing'.

The prostate is a small gland, roughly the size of a walnut, that sits just below the bladder. The tube that carries urine out of the body — the urethra — passes directly through the middle of the prostate. From about the mid-forties onwards it is very common for the gland to grow gradually. This is called benign prostatic hyperplasia, or BPH. Because the urethra runs through the middle, even a modest increase in size can gently narrow the passage. This may explain a weaker stream, hesitancy at the start of urination and incomplete bladder emptying — all of which can lead to the bladder filling again more quickly overnight.

Nocturia can also reflect changes in the bladder itself, fluid balance, sleep patterns, medications, caffeine and alcohol intake, or medical conditions such as diabetes. Because more than one factor is often involved, healthcare professionals typically look at the whole picture rather than focusing on any single explanation.

Occasionally, urinary changes are the first sign of something that benefits from earlier assessment — a urinary infection, a bladder problem or, less commonly, prostate cancer. Straightforward tests and examinations exist to help distinguish between these possibilities, and most men who raise these symptoms are ultimately reassured.

In men over about 50, the most common explanation for the pattern described above is benign prostatic hyperplasia — the gradual, age-related enlargement of the prostate. It is not cancer and does not turn into cancer, but it can genuinely affect quality of life, sleep and confidence.

Another possible cause is prostatitis — inflammation of the prostate, sometimes triggered by a low-grade infection. This can produce urinary symptoms, pelvic discomfort and, importantly for later laboratory interpretation, a temporarily raised PSA. Prostatitis is generally treatable, but it can be mistaken for a more serious condition if not recognised.

Bladder-driven causes are also common. With age, the bladder muscle can become more sensitive, producing urgent signals before the bladder is truly full — often described as an 'overactive bladder'. Diabetes, poorly controlled blood sugar and sleep disorders such as sleep apnoea may also contribute to night-time urination. Fluid balance can play a role too: if fluid gathers in the legs during the day and is reabsorbed on lying down, the kidneys process it overnight.

Prostate cancer does exist and is never ignored, but early prostate cancer usually causes no symptoms at all. When urinary symptoms are the presenting concern, the balance of probability strongly favours a benign explanation. Factors that may prompt closer investigation include a family history of prostate or related cancers (particularly in a father or brother), Black African or Caribbean heritage, older age, or a PSA that is rising over time. Early detection in higher-risk groups can genuinely change outcomes, which is why these factors are given weight.

Laboratory tests are often the part of a prostate assessment that patients understand the least — and worry about the most. Understanding what each test measures, and what it does not, can make later conversations with a healthcare professional far more productive.

The cornerstone investigation is a blood test for PSA — Prostate-Specific Antigen. PSA is a protein produced almost exclusively by prostate cells, measured in nanograms per millilitre. Some PSA in the blood is entirely normal. What matters is whether the level fits the person's age and clinical picture, and whether it changes over time. A single number is a snapshot; a trend is a story. If a PSA is mildly raised, healthcare professionals often simply repeat it — ideally after avoiding ejaculation, vigorous cycling and any urinary infection for a short period beforehand, all of which can transiently raise the number.

Alongside PSA, a full blood count and kidney function tests are commonly requested, and the urine is usually dipped. The full blood count gives a broad picture of general health. Kidney function matters because when urine is not flowing well, the kidneys can be affected over time. The urine dip screens for infection and blood — either of which changes how other results are interpreted.

If PSA is genuinely raised or the clinical picture warrants it, the next step is typically a multi-parametric MRI of the prostate. This is a non-invasive scan performed in the radiology department, allowing a specialist radiologist to look at the whole gland in detail. The MRI is scored, and only if there is a suspicious area is a targeted biopsy usually considered — where small tissue samples are taken and examined by a specialist pathologist in the laboratory. This 'MRI-first' pathway has significantly reduced the number of men undergoing unnecessary biopsies.

A digital rectal examination — a brief physical assessment of the size, shape and firmness of the gland — may also be offered. It is always performed by a trained clinician and interpreted alongside laboratory results.

A wide range of approaches may be considered, and the right starting point depends on how much symptoms are affecting daily life. Many men do not need medication at all. Others benefit from a simple tablet. A smaller number go on to procedures. Where cancer is confirmed, a modern spectrum of options can be tailored to the specific disease.

For benign enlargement or overactive bladder symptoms, lifestyle is usually considered first. Reducing caffeine and alcohol — particularly in the evening — can make a meaningful difference to night-time waking. Moving fluid intake earlier in the day (rather than restricting fluid), maintaining a healthy weight, treating constipation and staying physically active all support bladder and prostate health. Stopping smoking supports vascular and pelvic health more broadly.

Where lifestyle changes are not sufficient, well-established medications are available. Alpha-blockers relax the muscle at the neck of the bladder and improve flow. 5-alpha reductase inhibitors gradually shrink the prostate over months and are often useful for larger glands. Both are prescribed by a GP or urologist, are generally well tolerated, and have possible side effects worth discussing before starting. For overactive bladder, different medications that calm the bladder muscle may be considered. Where medication is insufficient, day-case procedures can safely reduce the prostate tissue that is obstructing flow.

For confirmed prostate cancer, modern management is highly individualised. Many low-risk cancers are safely managed with active surveillance — regular monitoring rather than immediate treatment. Others may be treated with surgery, radiotherapy or hormonal therapy, or a combination. Decisions are typically made by a multi-disciplinary team, and rarely need to be rushed.

Most prostate and urinary problems develop gradually and are not emergencies. However, certain symptoms usually warrant prompt medical assessment rather than a routine appointment. The following is general educational guidance — anyone concerned about their own symptoms should contact their healthcare professional or, in an emergency, local emergency services.

Preparing a few notes before an appointment can make a significant difference. Clinical appointments are often short, and a well-organised conversation helps get more from the same time. Writing down key questions in advance is welcomed by most healthcare professionals.
