The bladder, and the things nobody asks about

Urinary symptoms are among the most common things people do not mention to a clinician, and the average delay before seeking help for incontinence is measured in years.

What is normal

Passing urine roughly four to eight times in a day, with a comfortable interval between.

Getting up at night once at most in younger adults, with once or twice becoming more common with age.

Being able to defer for a reasonable period after first feeling the urge.

A steady stream with complete emptying.

Deviations from this are common and are not something to accept indefinitely.

The main patterns

Stress incontinence: leaking on coughing, sneezing, laughing, lifting or exercise.

The mechanism is inadequate support or sphincter function, and first-line treatment is supervised pelvic floor muscle training, which is effective in a majority.

Urge incontinence and overactive bladder: sudden compelling urgency, frequency and sometimes leaking before reaching the toilet.

First-line treatment is bladder training — gradually extending the interval — alongside fluid and caffeine adjustment, with medications and other options where that is insufficient.

Mixed, which is very common.

Overflow, from incomplete emptying, which needs assessment because it has causes including obstruction and neurological conditions.

Bladder training, which works

The counterintuitive part.

Going to the toilet "just in case", repeatedly, teaches the bladder to signal at ever smaller volumes, which reduces functional capacity and increases urgency.

Bladder training reverses this by deferring deliberately, starting with a few minutes and building up, using distraction and pelvic floor contractions to suppress the urge.

It takes weeks and has good evidence.

Restricting fluid, which people do instinctively, makes urine more concentrated and more irritating and makes symptoms worse.

Urinary tract infection

Common, particularly in women, and increasingly complicated by antibiotic resistance.

Typical symptoms are burning, frequency, urgency and lower abdominal discomfort.

In older adults presentation is frequently atypical, and confusion attributed to infection is a source of considerable overdiagnosis — asymptomatic bacteria in the urine are common in older people and current guidance advises against treating them, since treatment does not help and drives resistance.

Features requiring urgent attention: fever, flank pain, vomiting, or feeling systemically unwell, which suggest kidney involvement.

Blood in the urine always requires assessment, even if it settles and even if there is an obvious explanation.

For recurrent infection, options include vaginal oestrogen in postmenopausal women, which has good evidence, methenamine, which is being used increasingly as an antibiotic-sparing option, behavioural measures and in some cases prophylaxis.

Cranberry products have a modest and much-debated evidence base and are not a treatment for an established infection.

Men and the prostate

Where lower urinary tract symptoms are frequently attributed automatically.

Benign prostatic enlargement causes hesitancy, weak stream, incomplete emptying, dribbling and nocturia, and has effective medical and surgical treatments.

Not all male urinary symptoms are prostatic, and overactive bladder occurs in men too.

Any blood in the urine, sudden inability to pass urine, or unexplained weight loss and bone pain requires prompt assessment.

Prostate cancer screening is a genuinely nuanced decision involving overdiagnosis, and is worth discussing properly rather than being either demanded or dismissed.

What irritates the bladder

Individually variable and worth testing rather than assuming.

Caffeine, which has the most consistent evidence.

Alcohol.

Artificial sweeteners in some people.

Carbonated drinks.

Very acidic foods and drinks.

Testing by removing one at a time for a fortnight is more informative than removing everything at once.

What to do

Keep a bladder diary for three days — times, volumes, fluid intake, urgency and leakage — which is the single most useful thing to bring to an appointment and which frequently reveals the pattern on its own.

Do pelvic floor training properly, ideally with instruction, as discussed elsewhere on this site.

Drink adequately rather than restricting.

Treat constipation, which affects bladder function directly.

Stop going just in case.

And raise it, since the treatments are effective and the main reason they are not used is that nobody mentions the problem.

General information only, not medical advice. Consult a qualified clinician about urinary symptoms, and seek urgent assessment for blood in the urine or fever with flank pain.
